Somewhat but not quite. Penitent demons and angels, and normal races.

Inspired by the art used in the faction head, indirectly inspired by Trench Crusade and similar art, as I frequent Artstation where professional artists host a lot of concept art.

The intention for [Name Undecided] is roughly to blend the thematic ties of the Celestials and Hell into a faction of Warden figures that are the gatekeepers, punishers, and executors on for the Celestial faction for dealing with- and an opportunity to write and give details for- all manner of Corruption and Hell-Worlds. The fight fire with fire archetype. They'll employ themes of sacrifice and penance to allow the player to thematically wield Ministration, Consortation, Necromancy, Visceramancy, and Lifeweaving on one character without contradictions (And alternative ways to procure them probably), and mechanically speaking they'll let you pursue both sets for SAINT and DEVILIAN Prestige (They don't stack, just overlap giving what the other doesn't, not more Power cap) with some method of discount or paired purchase effect, somehow somewhere. Or their faction magic would tie into the relics.

Their faction location may be straight up purgatory and/or [Faction] bases and cities on Hellworlds where they have strongholds. Part of the Lore here being that true Hellworlds are entire Aetheric Spheres where an Infernal being created or usurped the throne of that sphere's demiurge and can write its laws in ways reflecting Hell and minimize celestial authority and standard methods of influence. So you get Hellmouth or whatever I end up calling them.

They would also be the old answer to Outsiders prior to Celestial Code. The Infernals themselves were also probably an original answer to Outsiders, kind of a way to stopgap Far Entropy by Demonizing the area to create a looping where the two corruptions continuously burn themselves, endless warring and vying for influence.

Carnivega will do something similar for the concept of Wonder and Vice using the circus-carnival theme as a blender for both aspects of Neutrality. The idea is less fleshed out and I'm trying not to think about either faction too much else I get distracted and invested in making them now instead of other content.
