A chimera is a creature with body parts from multiple creatures, combined into a bizarre whole. They are usually winged, frequently have multiple heads from different creatures, and generally hostile. Most of these living amalgams fly, and some breathe fire or possess a deadly gaze or a poisonous bite or sting.
These monsters may be product of overambitious magecraft - the fusing of essences from three, four, or even five creatures to create a new and dangerous one.
The classic chimera has the body of a lion, with the heads of a lion, goat, and snake or dragon. It sometimes has wings in addition. A chimera sometimes has the snake head as its tail.
