The Autumn Wyvern Shoot

Each autumn, for just two weeks, the forests and mountains of Taynedale fall silent. Everybody knows what is coming: as the leaves begin to turn brown the cloud giants who rule the valley release their wyverns for their annual shoot. Nobody sane leaves sight of their bastle house until the leaves are beginning to fall and the hunt is over.

All year, the wyverns are fattened up on goats' meat and adolescent humans - one from each village. They are housed in special adamantine cages in each of the giants' estates, so small that they are unable to fly - this keeps their wing muscles artificially weakened. The combination of obesity and enfeeblement means that, when they are finally released, they can only manage short stuttering flights and must spend most of their time rushing about in the undergrowth until startled by the hunters.

The hunters themselves go out a week after the wyverns are released. Armed with huge composite bows, they stride out into the woods in search of their prey, accompanied by packs of tamed dire wolves who rove through the trees aiming to flush out quarry. The goal is to kill the flapping wyverns with single arrows through the heart or neck, although this takes exceptional shooting; more frequently the reptiles are brought down like pincushions by volleys of arrows and then savaged by the dire wolves when they crash to earth. Their bodies are hauled back to the giants' castles by teams of human servants with teams of oxen, and feasted on throughout the winter; sometimes the spoils are shared out among the local human serfs in special yuletide feasts.

Anybody travelling through Taynedale during the first half of the month of November may encounter wyverns, hunting parties, or both. Replace half of all entries on the random encounter table for those hexes with "wyvern" (75% of replaced entries) and "hunting party" (25% of replaced entries).

Wyvern: HD 7+7, AC 4, #ATT 2 (bite 2d6, stinger 1d6*), Move 60/Fly 120 (E). 
*Stinger is deadly poisonous on a failed save vs death
*Can only fly for 120 yards and must then rest for 6 turns

Hunting Parties consist of 2d6 cloud giants (HD 16+2, AC 4, #ATT 1 (short sword 3d4+11, composite bow 4d6+11), Move 180). Of these, 1 in 4 will be unarmed wolf handlers accompanied by 1d6 dire wolves each (HD 4+4, AC 6, #ATT 1 (bite 1d6+2), Move 180).  

There is a 1 in 3 chance each hunting party is accompanied by 1d3 teams of oxen with 1d4 human handlers. These are unarmed and 0-level.

Hunting parties generally have no interest per se in hunting humans, adventurers or otherwise, but their dire wolves are not so discerning.

Detective Work on Forgotten RPG Fanzines [Part I]

Somebody has, perhaps unlawfully, uploaded scans of the complete back catalogue of legendary 1990s role playing magazine arcane to t'internet. I've been enjoying reminiscing and being struck by how many things I remember in some of the editions; it's funny how vividly memories can come back to you even 20 years after the fact.

One feature that I had forgotten about was a regular update on RPG fanzines: basically, fanzine creators would send their wares into the magazine and the editor would provide details on how to get them. Out of curiosity, this evening when I got home from work I started googling some of them. I quickly found myself descending into a rabbit hole. There is something unbearably nostalgic in reading about these artifacts of an ancient era - the time of geocities, letters, international postal reply coupons, photocopies, staplers, the post. You can't help but feel an overwhelming sense of affection for that distant and optimistic decade, and a huge warm fuzzy glow for all of these dedicated amateurs slaving away over labours of love for (presumably) scant reward.

Here is what I have found regarding the 'zines mentioned in Issue #2:

Sumo's Karaoke Club: Described as a "well-written" 'zine respected for its direct attitude (the publisher "isn't afraid to print what he sees as the truth"). It seems to have been primarily focused on board games. It cost £2.95 per edition. I have managed to track down an index and some further information to this site (http://pages.pacificcoast.net/~greg/); apparently it ceased trading in 1998 but has a still-living descendant, Counter.

For Whom the Die Rolls: A play-by-mail 'zine which ran its own games (including Rail Baron and Railway Rivals) and had articles on how to run PBM games. It is listed as costing 30p plus P&P. Staggeringly, it still apparently existed through to 2014 (2014!!) and had 215 issues in its run. Its website and a back catalogue are all available here: http://www.fwtwr.com/fwtdr/

The Ides of March: Another play-by-mail 'zine specialising in Diplomacy. It is described as being "held together by one cock-eyed staple in the top left corner" and having a "lively" letters column. It cost £1. I have had difficulty finding information on it, although it is listed as number 64 diplomacy-archive.com's list of Greatest UK Diplomacy Zines of All Time (yes, really); in the same website's 1995 Zine Poll it came in at number 7 (although the publisher is castigated for his "insistence of winding up his subscribers through his own brand of moral Conservatism" - the snail-mail version of shitposting?). 

Vigilante: A free (yes - all you needed to do was send an SAE with international reply coupons to the Irish publisher) RPG 'zine specializing in WoD games. It is described as "pushing hard to achieve professional status" with "surprisingly good layout". I can find out absolutely nothing about it on the internet, and it seems to have disappeared without trace. 

Flagship: This seems like it was a big fish in the PBM pond - it even had separate editions for the UK, USA and Europe and its own Wikipedia entry. "Slick, clean, and extremely useful for anyone who is remotely interested in PBM games". It was £3 and staggeringly (again) it lasted for absolutely ages - 1983-2010. Its website states that it widened its coverage to board games and RPGs in later years.

Life's Rich Pageant: Another PBM specialist - a "grassroots fanzine that simply bubbles with enthusiasm". Information on this one is thin on the ground, although I found mention of it in another Diplomacy zine, Spring Offensive. (Why do I begin to get the impression you could write an entire PhD thesis on the world of Diplomacy 'zines?)

PBM Zine: An "amateurish" looking affair with well-written advice but "annoying" layout. It cost £1.50 and looks like it was very yellow. It has such an un-Google-able title I just couldn't find anything on it online. I expect there must be something on it somewhere.

One Man's Rubbish: Described as being expensive because it is £1 (£1!) for 24 pages, this is another PBM-focused affair which also published reviews of RPGs and card games. It "does not have any content of sufficient interest to make it worth buying regularly" (ooh, the burn). Oddly, there is an entire scan of one volume available online - you can read it here: http://www.whiningkentpigs.com/DW/oldzines/rubbish2.pdf. It is an amazing thing - articles on the Proper Care of Floppy Disks nestling alongside rules for Armchair Cricket and a History of Motorsport. It already had fifty readers by its second issue and what looks like a lively correspondence with its readership; to think that we used to actually communicate with each other with letters and do so voluminously. How the world has changed in 20 years.

Games Games Games or G3: Originally titled Small Furry Creatures Press, this 'zine seemingly had ambitions of getting into retailers and had a good reputation "as an oracle of advice and reviews for gamers". It was £1.95. There is a Wikipedia stub entry for the publisher; I also dug out this page, which says the 'zine went quiet in 2001 after its anniversary issue - which staggeringly (again, again), was #150.

Games Gazette: A "genuinely amateur magazine" stuffed with reviews of all kinds of games. It seems to have been old even in arcane's day (it had recently celebrated its 15th - 15th! - anniversary) and, staggeringly (again, again, again) still exists in the form of this website (which definitely has the same owner, a man called Chris Baylis).

There is way more - way, way fucking more - of this to follow.

Gigaku Demons [Work in Progress]

These evil spirits manifest themselves as pitch black, semi-corporeal figures who move with an unusual dance-like grace and wear face masks which are distinctly corporeal - one might say hypercorporeal - in the vividness of their colours and the way those colours seem to burn themselves into the retina like lights. Through the eye holes stare very human-looking eyes.

If the mask is ever removed the spirit is banished; this can be done by making a successful grappling attack with both hands and then winning a straight STR check against STR 16. The spirit is instantly extinguished from this world, never to return.

If a human being wears one of the masks then they gain the ability to invoke the relevant magical abilities of the spirit owner, but the mask cannot be then removed - doing so results in the wearer's instant death. The wearer's speech, vision and hearing are restricted and he is at a permanent -4 penalty to initiative rolls, DEX checks, reaction dice, and any dice roll requiring clear sight, speech or hearing.

Some of the gigaku demons also carry additional corporeal paraphernalia with magical or non-magical effects. Their use does not have the same drawbacks as wearing the masks.

The gigaku demons are as follows:

Governor of the Way: A male figure wearing a mask with a tall black head dress and long silk sheets flowing down the back like a cape. He can open and close portals at will, and force up to 15 HD of enemies to dance uncontrollably in a procession in any direction for 400 yards, 3 times per day. Victims are allowed saving throws if this would force them off cliffs or into water or other clearly life-threatening scenarios. He also carries a war fan which can be used to send messages over long distances; the user whispers his message and then flips the fan around back-to-front, and this sends the message to the desired target as long as he or she is in eye-shot.

HD 7, AB +8, AC 16, #ATT 2 (War fan 1d4+2, Tetsubo 1d6+2), Move 120 

Lion with Tamers: One of these figures wears a big, bright red lion mask with staring eyes and a grinning snarl. From the back of the mask flows a vivid blue cape which swirls behind the Lion as he dances and capers. His two companions wear brown head masks with ruddy red cheeks and carry poles with hoops on the ends; they attempt to capture the Lion but never succeed. The Lion can bestow curses three times per day, and the Tamers can remove them and all other maledictions, likewise three times per day. The Tamers' weapons protect them from any attack by a wild beast, making them impervious to harm from teeth and claws; they function as lassos. 

If encountered, both Lion and Tamers will plead for aid in defeating the other. Each will immediately betray the PCs as soon as they make a choice, attacking from behind when combat is joined.

Lion: HD 4, AB +5, AC 14, #ATT 2 (Bagh nakh 1d4+1 x 2), Move 120
Tamers: HD 2+2, AB +3, AC 14, #ATT 1 (Lassoo), Move 120

Duke of Wu: A mask portraying a stylized vision of a Chinese nobleman, with a black cap, placid features, and a supercilious beatific smile. The shade-like figure wearing it walks serenely back and forth with folded arms, taking small graceful steps and gazing about itself with an arrogant air. 

The Duke of Wu can cast charm person once a day, hold person three times a day, confusion three times a day, suggestion three times a day, and feeblemind three times a day.

HD 7, AB +3, AC 14, #ATT 1 (Cane, 1d4), Move 120

Wrestler and Strongman: Two figures who are always seen together, guarding the Duke of Wu. Their semi-corporeal forms are big and somehow hulking; the first wears a top-knotted mask with jowls, the second a brutish bald visage. The Duke of Wu may amuse himself by offering gold, magic items and so on to anyone who can beat either of his guards in a grappling bout; beforehand the challenger must also put forward a valuable item as a "stake". The Duke of Wu's stakes are:

1 - A random magic item
2 - A random 'special' treasure
3 - A random gem stone
4 - A random item of jewelry

The Wrestler and Strongman both have STR 18.

HD 5, AB +6, AC 15, #ATT 1 (Sumo rush 1d6+2), Move 120

Old Widower and Old Widower's Child: the former is a bent, warped shade wearing a narrow-faced head mask from which are draped long, frail-looking wisps of grey hair and moustaches. The latter is thin, as though an adolescent; his mask is smooth, red-cheeked, and has a bowl-like shock of shortish black hair. 

These spirits claim their wife/mother was stolen from them by the Duke of Wu, who forced her to suicide when he tired of her. They will say that they seek help in gaining revenge, in return for the granting of a boon which they will bestow on the most powerful of their future helpers. But the "boon" in fact binds the recipient to the Old Widower and his Child in perpetual service; it is a geas which they cast on the recipient as he bows before them, binding him in perpetual servitude and causing him to die if his new master is destroyed. The Old Widower and Child will use their new servant to amass wealth, sending him out into the world to bring them gold and silver. This geas can only be undone by a powerful magician using a remove curse spell.

The Old Widower can also cast Command, Glyph of Warding, Sticks to Snakes, and Insect Plague three times a day.

Old Widower: HD 3, AB +2, AC 12, #ATT 1 (Stick 1d4), Move 90
Old Widower's Child: HD 2, AB +1, AC 12, #ATT 1 (Tanto 1d4) Move 120

Garuda: a lithe humanoid figure wearing a mask depicting the divine bird-man of legend - a sharp yellow hooked beak, like a scimitar, and a vast semi-circular head-dress of colourful foot-long feathers extending all around the top of the skull. In each hand it carries a Karambit of Sharpness. It acts like a predatory bird - rapacious, intelligent, perceptive, implacable.

The Garuda is only interested in hunting, stalking and killing.

HD 7+3, AB +9, AC 16, #ATT 2 (Karambit 1d6+2 x 2 [special]), Move 120

Chinese Maiden: a diminutive, sylph-like form maintaining her elegant movements despite her tiny crushed feet. Her mask's features are thin, expressionless, and cold; a long braid of hair hangs down from the back almost reaching to the ground.

The Chinese Maiden is pursued everywhere by the Drunken Persian King and his Followers (see below); she is almost never seen without them being within earshot. The Drunken Persian King longs for her hand in marriage; she will never give it, but will call on him for aid without compunction.

The Chinese Maiden undertakes to marry anybody who can bring her a blue rose. She can cast ESP, Audible Glamer, Phantasmal Force, Stinking Cloud, Confusion, Fear and Passwall, all once per day.

HD 3+3, AB +1, AC 12, #ATT 0, Move 120

Drunken Persian King with Followers: A corpulent figure with exaggerated movements demonstrating the strange agility intoxication can bring. His mask has a long beard of horse hair and a tall gaudy brass hat. He carries a gourd from which he occasionally takes a swig; it never runs out of its contents and instantly intoxicates anybody drinking from it (-4 to all dice rolls) for 12 hours. The Drunken Persian King is accompanied everywhere by 12 followers, all of whom wear crude masks with incompetently-carved features.

The Drunken Persian King is a suitor of the Chinese Maiden. He and his followers are always loitering near her so that if she looks their way they can demonstrate the King's virtues as a husband. This might involve showing he can knock his followers over, lift them above his head, leap over them, and so on. 

Drunken Persian King: HD 5, AB +6, AC 14, #ATT 1 (Sabre 1d8), Move 120
Followers: HD 2, AB +3, AC 14, #ATT 1 (Halberd 1d8), Move 120

Monk: A small stooped figure carrying a gnarled cane and a begging bowl. His mask is bald, and lined with deep exaggerated wrinkles cut into the wooden "flesh".

The Monk begs for money for sustenance, holding out his bowl. Nobody he asks for money can resist giving him all of the coinage which they have about their person. This they deposit in his apparently bottomless bowl. The money is transported to the Monk's grotto, where he retreats each evening; there is always 2d1000 gold pieces' worth of random coinage in this cave.

If the Monk is attacked or his bowl stolen, it is revealed to be empty.

The Monk's cane can be used to cast Teleport three times per day.

HD 2+1, AB +1, AC 12, ATT 1 (Cane 1d3), Moe 90

New Rule: The Coterie

Comments on the last entry raised the possibility of playing a PC sage-with-bodyguard double-act. The sage gets the glory; the bodyguard gets the XP. This keeps sages nicely wimpy (why bother with the frivolities of combat or the hocus pocus party tricks of spellcasting?) while providing an outlet for their XP gains and proper protection for dangerous expeditions. I like the idea.

I wonder if it could be expanded to general play. Every time your character garners enough XP to gain a level you can instead elect to find him a henchman who the XP goes to. Your first level fighter could go up to second level.... or, instead, get a first level thief as a glamorous assistant. The XP left over (because a thief level costs so much less than a fighter one) gets saved towards that nice new first level magic-user you've had your eye on.

The DM might want to restrict the number of henchmen, chiefly at higher levels - big XP rewards could theoretically allow a PC to employ a miniature army of first level thieves. But then again that's not all that different to what happens at name level anyway. There's also a natural break on numbers because XP rewards get diluted the more henchmen there are - if a PC has five henchmen, all getting shares, he garners less XP to spend on his growing throng.

Thinking Aloud: Sages in the Underdark/Wildlife Photographers on Mars

One of the reasons I don't begrudge paying the TV license fee is BBC wildlife documentaries. (Do foreigners know that if you have a TV in Britain you have to pay a tax of £150 or so which goes to fund shite like Dr Who? Well...you do.) Blimey but we, as a nation, make bloody good wildlife documentaries. I have serious reservations about the way things have gone in recent years - there is way too much slo-mo and musical grandstanding in the recent big budget hits like Planet Earth II and Africa - but we are still streets ahead of the competition, and the excellent Springwatch is a great counterbalance to the OTT Attenborough flagships.

Ever since I was doing my old Monstrous Manual thread on rpg.net (see links to the right of this page), I have always had it in mind to do a game about the "sages" who appear in almost every entry speculating about monster origins, habits and behaviour. A campaign in which the PCs are a band of scholars heading out into the wilderness or underworld in search not of treasure but of knowledge about its denizens. Making records ("Ah, so the death mold uses sverfneblin tears as an aphrodisiac!") and getting XP for it.

You could do something similar about wildlife photographers - on MARS! or other alien environment of your choice. (Another variation would be idle aristocrats exploring the Lovecraftian Dreamlands or similar, taking Daguerrotype photographs with incredibly long exposure times and trying to stay alive long enough to get good shots.) PCs going out with the aim of documenting rather than looting - at most collecting samples.

The problem I invariably stumble against is how to measure success in such a game. So let's muse aloud. Getting XP for documenting facts about monsters can be calculable on a rarity basis (50 XP for uncommon, 250 XP for rare, and so on) but from there things would get complicated. You could divide or multiply the number of XP based on the clarity or accuracy of the information. You could also do it with the significance of the facts learned (appearance alone being a low XP reward; information about abilities being higher, and so on). And you could increase the ratio for the obscurity of the fact - it is harder to learn some abilities than others. If photographs were being used, the XP reward could be clarified by quality of the shot.

The problem is that you would end up spending a lot of time, I think, caught up in calculating XP, and consulting lists of XP for different monsters and/or categories of fact (how much XP is it worth to learn about a vampire's restriction on entering a home uninvited?, etc.). This would be a lot of work for DM and players alike. Are there any alternatives? Answers on a postcode or - at a push - a comment.

Bounded Serendipity and the Virtues of Flicking

I've got a thing for popular reference books. I can control it, though. I never let it get out of hand - only three or four books a night, and never enough to get more than a little bit educated.

The ultimate reference resource is wikipedia, of course, and I love getting lost on that website clicking from link to link, but its ubiquity had made the good old-fashioned coffee table reference book seem outmoded. This is a great shame, because physical reference books allow something no website can emulate - the flick-through. You can go to a random page on wikipedia if you want. But what you can't do is flick through all its entries rapidly and stop when something catches your eye. You can have serendipity, in other words, but not bounded serendipity.

Bounded serendipity is the function of a physical flick-through-able book. You pick it up. You flick through. You see something that intrigues you. You stop to make use of it. You repeat the exercise. It isn't random but nor is it structured. It provides value through being semi-random while making use of your own eye as final arbiter.

Bounded serendipity is one of the main reasons why physical bestiaries are important. Flicking through a bestiary will not give you purely random monsters like a generator could, but it will result in certain entries leaping out at you as you flick - influenced not by a dice roll but by subconscious creative forces. You need a monster for stocking a hex lair and as you page through your Monster Manual the Peryton stands out to you as somehow appropriate. It does not stand out through fluke alone but due to a mixture of fluke and deep creative tides churning somewhere in the ocean behind your eyes. It's a heady mixture of luck and unconscious choice.

The bounded serendipity of the flick-through also works well with spell lists and treasure tables for similar reasons, although a special mention has to be made of books of maps - whether fantasy maps or the road atlas variety.

The Hyena Who Ate the Colour from the Sky

She comes in the day and turns it into endless grey: a hyena with infinite greed who can fit all the colour of the sky inside her belly and still have room to swallow a thousand men whole. She stands twelve feet tall and drools foamy saliva all around her as she walks, and her cackling cry echoes through the landscape for miles around her.

HD 10, AC 2, #ATT 3 DMG Special/1d6+3/1d6+3 Move 180 ML 7
*The hyena's bite attack does 1d6 damage as she hoists her victim off the ground; in the next round she swallows him or her whole. Victims can be cut from her belly if she is killed but they will die within 3 rounds of swallowing.
*The hyena can suck the colour out of the sky, turning it permanently grey and rendering the sun a mere plain white orb for a radius of one mile. She can do this once a day. In colourless zones the plants gradually die and nothing will grow. If she is killed the colours of the sky can be removed from her belly and used by an elven weaver to create material for a dozen robes or other garments worth 1,000 gp each.
*She trails saliva everywhere and can be tracked without requiring any sort of dice roll.
*She is accompanied everywhere by a dozen slave males (2 HD, AC 6, #ATT 1, DMG 1d6, Move 180, ML 7).

The Back of the Garuda: Or, Yet Another High Concept Campaign Setting

The last thing I need to do is come with another high concept campaign setting (I already have the dreams of a sleeping crocodile to finish off, and then the megadungeon inside a giant tree...), but what the heck, why not jot this down while it's fresh on my mind?

Have a read of the wikipedia entry for Garuda, the mythical gigantic bird-gods of Asian legend. Check out this paragraph:

Garudas are the great golden-winged Peng birds. They also have the ability to grow large or small, and to appear and disappear at will. Their wingspan is 330 yojanas (one yojana being 8 miles long). With one flap of its wings, a Peng bird dries up the waters of the sea so that it can gobble up all the exposed dragons. With another flap of its wings, it can level the mountains by moving them into the ocean.

A bird with a wingspan of 2640 miles. I can only speculate on how big that would make a feather, but think about what kind of societies might exist buried down beneath the plumage in what would presumably be near-darkness. Underdark creatures burrowing through the skin. Cities built into the hollow spaces within the feathers (living on the brink of potential apocalypse when a feather comes loose or the bird gets too vigorous with its preening). Blood farmed (mined?) for food or other purposes. Constant efforts to overcome radical shifts in the direction of gravity as the bird alternates between flying and perching upright. Legends of the great open space above, which can only be seen by climbing far, far upwards beyond anybody's wildest imagining...

Maybe I ought to stop reading wikipedia entries.

If You Go Down to the Woods Today...



Whether the jungles of South East Asia, the taiga of Siberia, or the ancient mixed woodlands of Europe, forests fascinate me. I like being in them and I like thinking about them: to be in a forest is to be completely surrounded in a gaia-like ecosystem, made all the more interesting because it obscures your vision and plays tricks with sound. This means that exploring a forest is a bit like exploring an overland dungeon - you never know what is around the next corner.

There is also some sort of primitive fear - the fear of a Savannah-dwelling early human/primate - of those dark, closed-off, cool spaces. To stand in an open space looking at a wood is like standing at the threshold of another, different world. A world where you don't belong. A wild place.

Bill Bryson described being in a forest nicely in A Walk in the Woods:

Woods are not like other spaces. To begin with, they are cubic. Their trees surround you, loom over you, press in from all sides. Woods choke off views and leave you muddled and without bearings. They make you feel small and confused and vulnerable, like a small child lost in a crowd of strange legs. Stand in a desert or prairie and you know you are in a big space. Stand in the woods and you only sense it. They are vast, featureless nowheres. And they are alive.

But there are difficulties running games in forests realistically, by which I mean, without just being yet another bunch of adventure locales except featuring treants, dryads and wood elves rather than derro and drow and whatnot. Taking advantage of, and emphasising, the uniqueness of the forest as an environment. I think there are chiefly three sets of problems.

1) First, as Bryson also puts it, when describing the experience of actually walking through a forest for day after day:

There is no point in hurrying because you are not actually going anywhere. However far or long you plod, you are always in the same place: in the woods. It’s where you were yesterday, where you will be tomorrow. The woods is one boundless singularity. Every bend in the path presents a prospect indistinguishable from every other, every glimpse into the trees the same tangled mass. For all you know, your route could describe a very large, pointless circle. In a way, it would hardly matter.  
At times, you become almost certain that you slabbed this hillside three days ago, crossed this stream yesterday, clambered over this fallen tree at least twice today already. But most of the time you don’t think. No point. Instead, you exist in a kind of mobile Zen mode, your brain like a balloon tethered with string, accompanying but not actually part of the body below. Walking for hours and miles becomes as automatic, as unremarkable, as breathing. At the end of the day you don’t think, “Hey, I did sixteen miles today,” any more than you think, “Hey, I took eight-thousand breaths today.” It’s just what you do.

Existing in a mobile Zen mode is nice, but not really what an RPG session is all about. In other words, exploring a forest is fun and interesting, but in reality also full of nothing-much-at-all in terms of excitement, danger, and adventure.

You can add excitement, danger and adventure with random encounters, of course, or hex locations, or even pre-planned encounters, for that matter, but at some stage it seems to me that if you're doing that too much you're not really being faithful to the nature of being in a forest as opposed to other sorts of environment. Emptiness and featurelessness is part of what journeying through a forest is.

2) When you are walking through a forest, you get surprised by things all the time. It's not an environment for humans (unless perhaps you are born into a tribe in the Amazon, and even Amazonian tribespeople manipulate their "forest" environment a lot). Your senses don't function well there: your main strength is sight, which is rendered defunct by the lack of visibility, and in comparison to just about any animal you could name, you have pathetically rudimentary senses of smell and hearing. The long and short of it is: whatever is round the corner knows you are there before you know about its existence. You are forever flushing grouse, being scared out of your skin by sudden bird alarm calls, and trying to identify the sources of mysterious movements in the undergrowth. You could be hunted and stalked with embarrassing ease by any serious predator.

This would make for good natural world as survival horror gaming (there is death lurking everywhere and it will get you) but not, I think, a long-term campaign.

3) Forests are in a sense featureless, but if at any given moment you stop while walking through one, you will be confronted by a radically different geography than you would have five minutes earlier. There are inclines, crevasses, streams, clearings, fallen trees, boulders, pools, a whole array of different features swallowed up by the trees and undergrowth and suddenly revealed to you as you pass by. More than in any other environment, the surroundings really matter - there is stuff everywhere.

So a realistic encounter in a forest has to take account of that. Want to fire an arrow? Deal with the fact that it's more difficult for your target not to be in cover. Want to creep up on an enemy? Deal with twigs and dried leaves everywhere. It's not so much that there's plenty of scenery to interact with, it's that you are overwhelmed by scenery; you have scenery up to the eyeballs, more scenery than you know what to do with.

This, among other things, makes forest adventuring - doing justice to what makes a forest a forest - one of the true last great frontiers of gaming.
