Insidious, diabolical, and powerful creatures that are feared by all denizens of the dark. They are humanoid except for their head looks like a four-tentacled octopus. Its mouth, a revolting thing like a lamprey's maw, constantly drips an oily slime when it is not siphoning out the brains of living prey.
