Furcas

[1][2] He teaches Philosophy, Astronomy (Astrology to some authors), Rhetoric, Logic, Chiromancy and Pyromancy.

Furcas (also known as Ren Vacca) is depicted as a strong old man with white hair and a long white beard, who rides a horse while holding a sharp weapon (pitch fork).

Furcas is a knight and commeth foorth in the similitude of a cruell man, with a long beard and a hoarie head, he sitteth on a pale horse, carrieng in his hand a sharpe weapon, he perfectlie teacheth practike philosophie, rhetorike, logike, astronomie, chiromancie, pyromancie, and their parts: there obeie him twentie legions.Notably, the 1563 edition says Forcas is an alias of the demon Foras, but in the 1583 edition of Pseudomonarchia Daemonum, Forcas is established as a unique demon separate from Foras.

According to a translation by Joseph H. Peterson: Foras [*Forras], alias Forcas is a great president, and is seene in the forme of a strong man, and in humane shape, he understandeth the vertue of hearbs and pretious stones: he teacheth fullie logicke, ethicke, and their parts: he maketh a man invisible, wittie, eloquent, and to live long; he recovereth things lost, and discovereth [discloses] treasures, and is lord over nine and twentie legions.The etymology of his name may be derived from the Latin word furca, meaning fork,[6] or from Greco-Roman also meaning a sepulchre (tomb).

[7] Furcas is portrayed as a female teacher with a wide array of magical knowledge in Welcome to Demon School!
