Vassago 1

Vassago (also Vasago, Usagoo) is the third Goetic demon described in the Lesser Key of Solomon as a prince "of a good nature," despite being a demon and of the "same nature as Agares."

He rules twenty-six legions of spirits, and is summoned to tell magicians of past and future events and locate lost objects.

Vassago is mentioned in the Book of the Office of Spirits as Usagoo, appearing as an angel, "just and true in all his doings," with the powers of inciting the love of women and revealing hidden treasures, in addition to ruling twenty spirits.
