In Blish's work, Satan, having won Armageddon, summons to the Citadel of Dis those magicians whose conjuration had initiated the conflict. He hears their advice before informing them in Miltonic verse that he is now God but does not want to be, so Man must evolve towards that role. Four men stand before the huge form of the Dantean Satan, "...five hundred yards from crown to hoof...", with only his upper body reaching above the floor of the great hall of Pandemonium. (1)
In Carey's work, the situation is more complex but there is a similar scene. God is not dead but has withdrawn, leaving others to address the problems caused by his absence. Elaine Belloc, a British schoolgirl but the Archangel Michael's daughter, thus God's granddaughter, has absorbed Michael's demiugic energy and created a new universe. Controlling such power also enables her to prevent the otherwise inevitable dissolution of the original, now God-abandoned, universe.
At last, Elaine and Lucifer stand before the remnants of the Hellkin, the Heaven-host and the Army of the Damned in a massive amphitheatre of the fallen Silver City where Lucifer announces, "You're looking at your new God," adding to her, "...I was damned if it was going to be me. For what it's worth, I think you'll be an improvement on the old regime." (2)
Like Blish's Satan, Carey's Lucifer doesn't want Godhood but, in this case, an alternative candidate is already in place.
