The corpse spider hides in the thick jungle foliage, often in shallow burrows, and leaps out on the unwary. In combat, it tries to paralyze its prey, wrap it in webs, and haul it off, still living, to its larder. The larder of a corpse spider is filled with the drained husks of its victims, all wrapped in thick webbing. There are often interesting bits of treasure still on the corpses of the sentient beings it has drained. Instinct: To fill its larder

• Leap on the unwary
• Hide in the foliage
• Paralyzing venom

The hooting grew louder, and suddenly a swarm of apes swung into view. They were not large, but powerful, with the painted faces of mandrills and the powerful arms of chimpanzees. They fell on us like a rain, piling onto us and pummeling with their rock-hard fists, shrieking and hooting all the while. Instinct: Obey the Ape King

• Swarm through the trees
• Pile on a foe

Pale skin, like waterlogged corpses, but withered flesh, like dessicated mummies. They sprang from the bone piles and surrounded us in an instant. Strong, and tough, but we drove them off, though Fulgrim lost half is hand and a big chunk from his calf. Instinct: To consume

• Feast on flesh
• Spring from ambush

At first glance, it looked like a huge, winged tiger, all made of shifting shadows. When it moved, though, the proportions shifted and changed in a most unnatural way - as if the shadows were not used to having to hold a shape and form in the material world. It flowed, liquid-like, through its paces and, when it took to the air, the distortions were even worse. Sometimes, it seemed to pass portions of its body through solid objects, but other times, it moved around them. The shadows followed it, and cloaked it, and sprayed out over its foes. Through it all, the vicious, slashing claws and teeth, black as night, black as the void, cut and danced. Instinct: To guard the pit

• Rend a foe limb from limb
• Wrap shadows around itself or a target

"They'd been stalking us for day, but we never saw them. See, the place was riddled with these little holes - in the walls, in the floor, in the ceiling - and they'd use those for getting around. So, yeah, never saw them. But we knew they were there, because our stuff kept vanishing. First, I woke up and a quiver of my arrows was just gone. Little scrape marks around where it had been sitting, no other sign. Next day, Fulgrim's whining about how his food bag, with all his jerky and figs, was missing. Stuff like that. "Then, as we're climbing up out of this hole in the side of the temple, Fulgrim's the last one out, and he comes barreling out of there, swinging his torch around him like a maniac. Almost clips me in the side of the head with it. Says they started popping out of the little holes as soon as he was alone - dozens of 'em. Says they were spiders, about the size of a big rat, with the heads of bats. Maybe stingers, he says, like scorpions. Coulda had wings, maybe. He didn't stick around to find out. "We started setting double watches after that." Instinct: To collect items

• Steal an item
• Swarm over a foe

The Forest Devil has inch-long, razor sharp claws and teeth like a mouth of broken glass shards. It's patchy coat is a mottled green and brown, and its eyes are black and shiny. The favourite tactic of the Forest Devil is to stalk travelers through the woods by creeping through the tree canopy, and pounce on any target that strays far enough away from the others. Ideally, it kills quickly, and retreats back into the leaf cover with its prize. Instinct: To eat.

• Move stealthily through the tree canopy.
• Attack from above.
