Phenex
In demonology, Phenex (also spelled Pheynix, Phoenix, or Phoeniex) is a Goetic demon. A Great Marquis of Hell, he is said to have 20 legions of demons under his command. He appears as a phoenix with the siren-like singing voice of a child. He teaches sciences, is an excellent poet, and is very obedient to the conjuror once he takes human form. Phenex hopes to return to the seventh throne of Heaven after 1,200 years.
