Pandorans are creatures spawned when a Promethean's creation rite goes horribly wrong. Instead of creating a whole Promethean, the process transforms pieces of the reassembled corpse into small living creatures of a variety of shapes and abilities.
Pandorans require Azoth to remain animate; without it, they enter Dormancy. In this dormant state, they resemble inanimate objects of varying types and sizes - anything from lumps of wood or rock through to sculptures or statues. They can even be shaped in the same ways as the objects they resemble.
