Beleth

Beleth: "He rides a pale horse, and all kinds of music is heard before him, according to most authors on demonology and the most known grimoires. ... When appearing he looks very fierce to frighten the conjurer or to see if he is courageous. The conjurer must be brave, and holding a hazel wand in his hand must draw a triangle by striking towards the South, East, and upwards, then commanding Beleth into it by means of some conjurations."
