The dark forest you have been passing through has been getting more dense, tangled & gloomier than before. The thick, twisted tree trunks, unnaturally misshapen limbs, writhing roots, clutching & grasping thorns & briars all seem to warn & ward you off, but you have forced & hacked your way through regardless. Going through the dark forest that presses close to either side brings you at last through the thick belt of trees & now the strange growth has suddenly ended - you have crawled out of the thicket onto the rim of a ravine-like area.
The walls of the ravine rise rather steeply on either side to a height of around 100 feet or so, you guess - dark, streaked rock mingled with earth. You have no doubt you can climb them, but you'd need both hands. Clumps of trees grow here & there, both on the floor of the ravine & up the sloping walls of the canyon, which could hide almost anything up to & possibly including a giant.
A narrow stream, likely the Goblinwater, trickles down the center of the ravine, forming great muddy puddles in several places, its source hidden in the trees that cluster at the west end of the ravine. The opening to the east appears to be about 200 feet wide. The ravine runs at least 400 feet eastward, to where the western end you are near rises in a steep slope.
Here & there, at varying heights on all sides of the ravine, you can see the black mouths of Cave-like openings in the rock walls, crude paths leading up to them; more perhaps, hidden by the trees. The sunlight is dim the air is dank, there is an oppressive feeling here - as if something evil is watching & waiting to pounce upon you.
There are bare, dead trees here & there as well, & upon one a vulture perches & gazes hungrily at you. A flock of ravens rise croaking from the ground, the beat of their wings & their cries magnified by the terrain to sound loud & horrible.
Amongst the litter of rubble, boulders, & dead wood scattered about on the ravine floor, you can see bits of gleaming ivory & white - As a chill wind blows into your face you feel sure that you have in fact discovered the famous Caves of Chaos, where many an adventurer has sought fame & left only his or her bones behind!
