Shax (also spelled Chax, Shan, Shass, Shaz, and Scox) is a Great Marquis of Hell, and has power over 30 legions of demons on evil horses.
He is depicted as a stork that speaks with a hoarse but subtle voice; his voice changes into a beautiful one once he enters the magic triangle.
He takes away the sight, hearing and understanding of any person under the conjurer's request, and steals money out of kings' houses, carrying it back to the people. He also steals horses and everything the conjurer asks.
Shax can also discover hidden things if they are not kept by evil spirits, and sometimes gives good familiars, but sometimes those familiars deceive the conjurer. He should not be bothered too often.
Shax is thought to be faithful and obedient, but is a great liar and will deceive the conjurer unless obliged to enter a magic triangle drawn on the floor. He will then speak marvellously and tell the truth. He knows when lies are told and uses these to teach lessons.
