Valefor

Tempts thieves to steal. Serves as an excellent familiar.

This one tempts thieves to steal and then this other guy Andromalius, punishes them, I like to say with divine guidance, which is actually mind control. But neither here nor there.... I just like to give everything a spark of light in the darkness of it all.

A demon connected with thieves. He is the sixth spirit named among the seventy-two demons of the Goetia. In Wierus's Pseudomonarchia Daemonum, he is said to be very familiar with those who seek him out, but he ultimately leads these individuals to no greater fate than the gallows. According to this text, he takes the unlikely shape of a lion with the head of a thief. He is a strong duke with ten legions of spirits under his command. An alternate version of his name is given as Malaphar. This is rendered Malephar in Scot's Discoverie of Witchcraft. In the Goetia of Dr. Rudd, Valefar is said to appear as a lion with a man's head, howling. Rather than being specifically attracted to working with thieves, according to this text, Valefar tempts people to steal. Despite this, he is said to make a good familiar. He is constrained with the name of the angel Jelahel. See also GOETIA, RUDD, SCOT, WIERUS.
