Enigma

Enigma is an ancient being. He is a master of illusions, and the king of dangerous tricks and cunning riddles. He waits for travelers, and appears in an innocent form, waiting to pounce. He always asks 5 riddles. If you get but one wrong, he gets to mind control you, or take you as a slave. (Y'all liked the Spinx, so I figured you could put up with another riddle master)
