Five Visions of Hell

Commonly said to be written by Yakov Dilisnya, Five Visions of Hell is a written work describing the writer's visions of hell. A lemure, a barbazu, an imp, and possibly other devils are all described, but it is unknown how much the specific monsters are recognized by the writer or the readers of the work.

Text extracts as follows:

For the barbazu:
There is no house among the Dukes of Hell who have not their own guards and sentinels, of whom the great majority are great bearded devils, anthropomorphous, though with a long tail, clawed on both hands and feet; their beards are a great source of pride to such, and a devil of this sort bathes its beard in the ichor of those they have slain in combat to work them into fantastical shapes and great matted tangles; a long beard soaked with the blood of many enemies is a mark of status among them, and to be shaved is their great fear, far more than of death.

for the imp:
There are also in that place any number of lesser devils, among whom I saw a great number of bat-winged, scorpion-tailed mannikins of the size of a newborn child, whose employment is to attach themselves as familiar spirits, either to a greater devil or to those who fancy themselves masters of the Arcane Art; these latter they drive to perversions and abominations, tempting them to ever-greater abuses of that power which no wise man takes upon himself.

For the lemure:
I saw also the most wretched of creatures, like men degenerated into jellies, mired in the most horrible fear of their masters and loathing of themselves; they covered the floor of Hell like maggots on a rotting corpse for many leagues in all directions. In them I saw the ignominy, the weakness, the stupidity of all evil actions clearly drawn.
