Apocrypha
In Dragon # 28, the article "The Politics of Hell" by Alexander von Thorn gives a different history to that detailed above, and includes statistics for Satan, Belial and Astaroth. Satan is more powerful than any other Devil, but lacks support, having been exiled from hell by Beelzebub following a revolution. Beelzebub ("Lord of the Archdevils") was himself overthrown by Asmodeus and is forever after known as Baalzebul ("Lord of the Flies," with "flies" meaning "little devils" in this context).
In Legions of Hell by Chris Pramas, Beelzebub (as he's called in that source) is described as a fallen throne archon. His servants in that book include Amitiel, the Archon of Truth; Flauros, who is consulted in divinations; Meresin, who controls lightning storms; Moloch, a former angelic patron of children who now welcomes child sacrifice; Murmur, who questions souls arriving in the Seventh Circle; Nergal, the Fetid Prince; Rahbad, Lord of the Lightless Seas; and Tamiel, Angel of the Deep.
