The Necromancer Games forum thing is interesting. For example, its interpretation of Gresil is inspired by my page, which is in turn heavily inspired by Grodog's page, sort of combined with stuff on the Mimir (I can't remember why I put Gresil in Falserapture, but I remember being in love with the idea). The version of Obox-Ob is mostly from mine, which is partly from Grodog and partly from a post by Leo Wilheim on the Planescape mailing list, and partly from my own imagination. The Soneillon thing is partly from the lilim demons in the Netbook of Witches and Warlocks, partly from Grodog, and the author on those boards added more to the description. J'sald Xerix is from the Netbook of the Abyss. Zzyczesiya is named in Faces of Evil and detailed by me, with inspiration from the Infernus netbook. The Knight Errant is from Faces of Evil. Lots of the lords are from
Armies of the Abyss or Mongoose's
Slayer's Guide to Demons (which is where the Nameless Ones come from). Ushablator was named by Gary Gygax and first detailed
here. Eblis' description is partially based on that of Azazel in Neil Gaiman's Sandman series - the name Nakdar Nakoul comes from an Arabic phrase meaning "I can eat glass; it does not hurt me," so I think it's really funny that someone repeated that, apparently not knowing its goofy origins. It was back when I didn't know what the Muslim Hell was supposed to be called, so I used a random Arabic phrase. Djahannam is the proper name of the Muslim Hell. Brian Biddick, on the Planescape list (whose influence runs throughout), was the first one to assign Munkir and Nekir to Woeful Escarond. They shouldn't be the rulers of the layer, though - the
Marquesse of Loss, described in
Hellbound, is more important there. Mandrillagon comes from the Gord novels, as does a lot of the descriptions of Orcus, Demogorgon, Graz'zt, Verin, etc. Zalintar, mentioned in Yeenoghu's description, is from the old planescape.com site, now long since extinct but findable at archive.org. There's quite a lot from the Netbook of Demons, too.
