Here are a pair of very loose concepts, both of which will be refined, uh, I guess when things become clearer.
The Stygian Celebrant, The Rejoicing Lorekeeper, Daybreak Caste Abyssal
-- A necromancer and sorceress both, the Stygian Celebrant is a lorekeeper and historian above all things, with a fixation on the remnants of nations long since forgotten -- mortal and supernatural alike. She has a strong love for the city of Sijan, which features a culture that has remained unmarred for centuries (if not longer) and does not distinguish between the culture of the living and the culture of the dead.
Presently, the Stygian Celebrant tends to have a strange obsession with introducing the manners and customs of long-dead peoples into [wherever the Solar Circle is busy being amazing]. There is no Abyssal without a desire to destroy, however -- and the Rejoicing Lorekeeper hopes to erode, eradicate even, the wall of stigma and fear that segregates Creation's living and dead.
Exquisitely Efficient Esther, Defiler Caste Green Sun Prince
Esther is a renegade of a sort -- in the sense that she does not flee, but simply spits in the eyes of her pursuer. Only briefly a loyalist toward the plans of the Yozis, Esther's willingness to serve them faltered quickly upon exposure to hell, and more quickly yet upon interaction with the infernal souls of the Yozi rulers therein. She has love for only one of the fallen Primordials, and that is her patron, She Who Lives In Her Name.
Esther is fixated on the concept of a perfect world: everything in its place, clearly defined, well-made and perfectly functional. She is obsessed with ideas of efficiency and regularity. She knows that, should the Yozis return, or the Neverborn have their way, the world will only be uglier than it is now. She has considered that the Deathlord's ends -- the end of all things equally, forever, has a certain pleasurable uniformity to it, but the lack of function or direction bothers her.
Esther would be a sorceress and martial artist (probably) with desires to regulate and control ... everything. But not in a cruel way, just a 'better for everyone' way. She may conclude that she belongs higher on the hierarchy and expect worship, but that depends on where the game ends up set, which is important.
My vote is just 'not the scavenger lands'. :p
