The Nights of Revelation

Half God Half Devil
I won't pretend that I resist temptation
I think it's funny when you preach damnation
I've been to hell and back and now it's just a part of me
Without the darkness there'd be no light in me

Half God Half Devil - In This Moment

Found in the center of the Pit at the deepest levels of Hell, Lucifer Morningstar was released through the actions of his brother Kushiel and host Charlie Van Rensselaer, Vic, Dahlia, Andi Pascek, Nyx and in trade with Seamus Mulcahy who willingly took His place within Perdition.

His motivations and personality have yet to be revealed beyond a strong affection for Kushiel, embracing the fellow Fallen upon leaving his Cage.

Due to taking part in the ritual performed by Becca Whateley, Lucifer possesses knowledge of the Apocalypse and the Final Nights firsthand. It was decided by Rosalie that he would serve as backup for the mission at the hotel Provincial posing as her assistant, going by the quickly scrambled alias of Lucien Morgenstern when left to his own devices mingling with the other attendees. During the quarantine and major Masquerade breach at the charity event co-hosted by Cardinal Valdis and Tobias Wren, Lucifer was witness to the toast that infected all those who took part with the Wyrm, helping Whiskey retrieve Beleth after he lost consciousness, and the subsequent cleansing of the fire suppression system in the basement boiler room.

Currently Byron (and therefore Beleth) are being held captive and watched over by Lovecraft, Lucifer, and Whiskey at Oliver's request.

After the exorcism at the Audubon Zoo in New Orleans, Beleth has been cast out of Byron and is presumably returned to the Pit.

With Whiskey's aid, Lucifer have been securing a place in mortal society for him (as the identity as Lucien Morgenstern) as well as gathering any information they can about the Earthbound's comings and goings.
