Continuing The Ars Goetia. The Ars Goetia is the first section of the Lesser Key of Solomon, containing descriptions of seventy-two demons.
These are an eclectic bunch made up of demons/pre abrahamic faith deities in demon form.
Buer is a Great President of Hell and the commander of 50 legions. Buer appears either as a centaur or more commonly a lion headed beast with multiple goat legs to walk in all directions. He is a teacher of natural and moral philosophy, logic and all virtues of plants and herbs. I kept it pretty close to the Ars Goetia depiction because a flaming lion head with legs is pretty bizarre to begin with.
