Baalzebul was the lord of Maladomini, the seventh layer of the Nine Hells, and one of the most powerful archdevils. Formerly a celestial archon known as Triel, he bore the titles Fallen One, Lord of the Flies, Lord of the Lies, and the Slug Archduke. The last refers to the form he was cursed with after the Reckoning of Hell; Asmodeus has made his natural form that of a filth-covered giant slug with tiny arms.
