Fulmin

Fulmin is a caricature featured in the official lore A Return to Stone. He is a mage who was granted immortality by a demon from the Infernal Dimensions on the condition that, when his body is about to die, he can take over the body of someone else. Should he fail, he will be tormented by the demons for eternity. During the lore he attempts to take over a long-lived TzHaar body, and discovers the abnormal TzHaar hatchling Ga'al-Rek. Fulmin offers to take Ga'al-Rek to the surface of the volcano, but is killed by a TzHaar. Presumably, he is now in a state of eternal torment.
