The Library / The bestiary
Living and dead, as the client draws them
Every creature the client names, and what it leaves behind.
The client carries a list of 833 creatures, and the sprite the game actually draws for every one of them -- shown here facing south, the way you meet them.
Where a creature leaves a named corpse, the corpse objects are shown beside it, in decay order. Only 59 creatures have one, because the client names corpses generically: a single "dead orc" stands in for every kind of orc, and most creatures have no named corpse object at all.
Creature sprites are outfits rather than objects, and a creature is keyed twice: once by the bestiary race number you see here, and once by a looktype that selects its appearance. The two agree for the oldest monsters and part company for most of the rest.
Taken from client version 15.32.f84c0e. Creature lists and sprites change between releases, so this is a snapshot.
