Haborym (aka Aym) is a fire demon and a duke of hell, who commands 26 legions. He appears holding a torch and riding a viper and he has 3 heads: a serpent, a man, and a cat. Some say he is the same as Raum.

Goetia – S. L. MacGregor Mathers (1904) (quoted)
The Twenty-third Spirit is Aim. He is a Great Strong Duke. He appeareth in the form of a very handsome Man in body, but with three Heads; the first, like a Serpent, the second like a Man having two Stars on his Forehead, the third like a Calf. He rideth on a Viper, carrying a Firebrand in his Hand, wherewith he setteth cities, castles, and great Places, on fire. He maketh thee witty in all manner of ways, and giveth true answers unto private matters. He governeth 26 Legions of Inferior Spirits; and his Seal is this, which wear thou as aforesaid, etc.
