The Fallen General of Hell
also called “Lord General”; “The Black General”; “He”; “The Black”; “Warlock”
He is known to have been banned from the Nine Hells after attempting and nearly succeeding in overthrowing Prince of the Hells, Mephistopheles.
He is known now as the Protector of the Mythlar device. To what end, he never really explains how or why he is the Protector. Only that he is and he has an agenda to protect it at all costs.
He was tricked into working with the Red Wizards, though with the party’s help he has now broken free of those bonds and is once again working for himself though seems to have some diabolic pleasure working with the party providing a stone dagger in which they might call upon him and maybe he might call upon them as well?
