the depths

ZONE

stop rolling d4s when you get to the crater

	terrain	encounter
1	lake, the water tinted wrong. steaming banks swarmed thick by bloated flies	toads as big as dogs. d3+4 of them, with d3+4 legs each, twitching grumpily. their venom causes hallucinations of an earth destroyed and reborn. seizures at higher dose
2	pines. mostly toppled. caught like pick-up-sticks in each others arms	deer blasted into after-images. skittish. flickering blackwhite silhouettes leap away over the brush. if a buck runs through you your bones glow through your skin like an xray
3	heath. wildflowers in a thousand coruscating shades, each a tiny atomic sunset	brainwolves. lobes bared like teeth from the top of their head, spilled from the hollow where eyes should be. only d4+1 left in the pack, their minds meshed in howling psychic echolocation
4	crater punched hard into the rock, cracks still sizzling with radioactive heat	armoured personnel, bodies helplessly melted into their truck, souls fused in the plutonium forge. their chassis is irreparably torn, engine near liquid with heat. hunting officers, scientists and politicians
5	crater	angered earth. the bomb lodged in its chest a nuclear heart, overflown with hateful passion. titanic fists obliterate themselves against anything it can reach. it scoops a handful of dirt and screams at it until the atoms burn off
6+	crater	torn reality. something is visible on the other side. god, probably. an alien world and your childhood home. reality has been undone, memetic tumours are all that's left. it's every burning future all at once. a perfect void but no vacuum; you realise that our world is hollow now too

HYPERAUSTRALIS

best way to get back to earth is to climb the nearest mountain, wait for a snowstorm, then jump off a cliff
roll d6s, adjust depth as instructed, minimum 0

1	playful platypus, as long as your arm and twice as friendly. its fur is worth an inestimable fortune. its venom could kill you in seconds depth +1
2	herd of brumbies. shaggy steppe ponies grown huge and wild in hyperaustralian air. stumbled in from somewhere in the himalayas, they're breeding out of control and wreaking havoc in this alien ecosystem depth +1
3	lyrebird skulks just out of sight. tired of scratching in the dirt for bugs it calls to you, testing cries and words to find what sequence of sounds might encourage you towards a clumsy death depth +1, and the bird follows you
4	hundred-strong mob of roo grazes, indolent but fiercely territorial. one of the larger will sway up to you to pick a fight. the legs hit like a log trap, though if you can knock it down the rest will let you pass without issue defeat a roo or depth -1
5	lone echidna, bear-sized, snuffles in the dirt. its quills are said to carry great potency of an unspecified kind. follow it long enough, collecting dropped barbs, and it will lead you far, far from its nest and your path depth -2 if you follow it, else depth +1
6	the wombat is nowhere to be seen, though its den is impossible to miss. earth gouged by paws fatter than your torso. soft square spoor the size of your fist. the cool breeze wafting from the tunnel suggests it may lead just where you're headed depth -2+d4 if you take the tunnel. encounter a pissed off diprotodon if you come back through otherwise, depth +1
7	crimson rosellas, their wings a dozen shades of snowstorm blue. they squawk and giggle in the trees, the first flakes of snow falling around them. somewhere between beautiful and ear-splittingly annoying. if you try to camp near them you won't sleep a wink depth +1
8	the rock here is bare, thin snow failing to congeal in the near-constant wind. this peak is not yet high enough, though the view is quite beautiful depth -1
9	finally the snow thickens, trackless and serene. just under the surface pygmy possums lair. too much weight on the crust and you'll punch through into their den. their swarming bites are rarely lethal, so long as someone helps pulls you out depth +1
10+	the peak is flat, almost disappointing, uneventful until night falls. the aurora australis roars overhead, colours calling to you even in your dreams. too much time spent up here, before the snows come to open a path back home, and you might never want to leave

THE ANCIENT PAST
start at depth 1. instead of just +1 per step add the result of your d6. if you go off the end of the table you wrap back around to the start

1	present day. five minutes have passed every time you go through a whole loop
2	bronze age. arching sandstone cities in the distance, lit by a sumptuous purple sky. to either side a sweating, confused gladiator, their duel interrupted
3	ice age. sleet sheets cuts through cloth like a sickle. from the bones of your feet comes thunder - a mammoth stampede driven before pelt-draped hunters
4	meteor impact. sky is thick with smog, white-hot trails cutting through from the ruination flying overhead
5	triassic jungle. towering ferns busied by mosquitoes big as birds. behind you a trex, sniffing curiously
6	flooded. warm, shallow sea. skittering clockwork arthopods bicker below. the 10ft of water above your head teems with motes of near-microscopic life
7	mossworld. utterly tranquil, though the air is a little thin. sky a light, fresh blue. nothing but mosses and extremely dumb bugs.
8	endless rains. the rock hot underfoot, only recently cooled enough to let liquid water form. high above are all the world's oceans, still a broiling cloud thick with lightning
9	molten earth. a tiny promontory of basalt thrust up from seas of magma, slowly tipping back down into the heat
10	time engine. hazmat suited figures with bulging heads and the wrong number of fingers. they fiddle with knobs and radio in for timemarines to stop your nefarious meddling

DEPTH TABBLES

d10s

1	okay so you like add 'depth' to your roll to indicate that you're moving through something?	11	oh christ and variance is a whole thing?? the smaller the die you're rolling the higher chance of doubles, and the less likely to miss things
2	wait so you've only got one chance to see the first thing on the table? it better be a special one...	12	can always double up entries, too, to smooth out the progression
3	but like you could still roll doubles, or get something that was higher up than what you just rolled; things can't be expected to occur in order	13	double ups in one column but not another? like the landscape column doesn't change much but encounters do
4	oh right and it doesn't have to be spatial. it could be temporal, or like stages of a disease or the passing of seasons	14	or, jeepers, different columns are different lengths?? like you have to get to a certain depth on one to get the really crazy shit, but the other column probably cuts you short?
5	huh you could even have the table be a loop, that you just keep wrapping around	15	you could even roll different sized dice but that sounds kind of fucked
6	and entries could totally tell you how much to change depth by	16	you definitely want to preroll everything if you're doing a spatial one. it's more like procedural generation at that point
7	or wow even just jump you to a specific point on the table	17	but the more reactive ones.. you could maybe do social encounters through them, even build a generalised one, like peril dice or whatever
8	obviously you can give it multiple columns, to get some of that sweet precious permutation going	18	every table probably does need specific rules. how to handle doubles, which of all these weird permutations it employs
9	or damn even multiple axes, so you can go deeper in different directions along, let's be real, probably just a grid	19	okay what if you simply reduced all human activity down to several thousand vectors, and all pc activities are coded into these at appropriate depth...
10	okay yeah what if the table doesn't even end at the point you've trying to get to? you can overshoot and then realise you have to backtrack or w/e	20	...and then u apply a depth mechanic to the process of developing depth mechanics, so u can depth mechanic while u
