Nergaliid

Nergaliids are rotund, scaled, frog-like demons, sometimes found in Xhorhas. According to the book The Fiends of Folklore, nergaliids were alleged to feed on people in the night while they slept. Kylre, a member of the Fletching and Moondrop Traveling Carnival of Curiosities, was a nergaliid posing as a lizard man until he began feeding openly.

Feeding habits
A nergaliid has two types of feeding habits:
 * The first method is slow. The fiend siphons off the life of mortal creatures, not in such a way that it leads to harm or the death of its victim. Their victims might not even notice that it is happening to them.
 * The second method of feeding is quick and causes much pain and anguish to its victim, leaving behind corrupted, undead husks.
