Need Advice for Dawn of Flame Drow

[Archpaladin Zousha]

I'm looking to get a character set up in case someone does a recruitment here for the Dawn of Flame adventure path, and I've got a core concept, but need assistance elaborating on that concept to create a complete character.

Since I'm already playing a Sarenrae-worshipping half-elf solarian in a game of Dead Suns on these boards, I started looking around for something different and was inspired by the description of Eclipse Academy on Apostae, reproduced here for convenience:

Pact Worlds, Pg. 133:

Very few outside of Apostae know about this obscure university located at the opposite end of the Hak Rifty from Nightarch. The majority of its students are drow looking to learn more about the light-based magic all drow are born with, while the rest are offworlders who have been invited to enroll because of their innate magical talents. Classes generally consist of grueling practical exercises where instructors push pupils to their physical and mental limits. Only one-fifth of every class graduates, the others dropping out because of the constant pressure or literally dying of exhaustion. Those who see the end of their 3-year course of study are some of the most talented mystics, solarians, and technomancers the universe has seen, though many have contracted serious mental illnesses and neuroses from the stress.

The majority of Eclipse Academy's campus is underground, with only a pitch-black ceramic tower marking the facility's entrance. Inside, the lecture halls and dormitories are sparse and functional with no lighting to speak of. Several drow houses secretly finance the university, paying for its food supplies, oxygen, and power while maintaining plausible deniability should the academy's cruel practices become known to the entire Pact Worlds.

My idea is to play a drow survivor of this academy, with possibly the Death-Touched theme to reflect how close to death its methods pushed her, and now that she's completed her training, she wants to leave the cruelty she suffered during her training and under Apostae's society as a whole behind. I'm struggling to decide what class she should ultimately be. My first instinct was another solarian, but with a solar weapon as opposed to my Dead Suns character, who uses solar armor. But a Star Shaman mystic would be thematically appropriate too, since what is the sun but a star?

I'm also trying to decide what kind of deity (and alignment) she would gravitate to as she's desperately looking for a purpose in life, but not Sarenrae as my Dead Suns character already is a Sarenite and because I imagine Sarenites will be a cred a dozen among potential applicants to a Dawn of Flame game. I've been thinking of possibly having her be a Knight of Golarion and worshiping Iomedae, deciding to use her star power for good, especially since in this video on the organization, the Knights protect and patronize any species that can trace their origins back to lost Golarion. While that's primarily humans, it also includes space goblins, dwarves, and yes, the drow. On the other hand, Desna is an appealing choice, given how she seems to attract bad people looking to become good, even a succubus, and I think James Jacobs stated that the Forgotten Realms goddess of good drow, Eilistraee, was an inspiration for Desna (I can't remember if it was specifically Desna he mentioned, so I could be wrong), and Desna isn't very demanding, plus travelling to interesting places like the sun and stuff would appeal to her, especially with the theme of discovery and exploration of the unknown the adventure path has.

So what do you folks think? Should my drow be a solarian, or a star shaman mystic? Should she worship Desna or Iomedae? Should she take an archetype like Star Knight or Divine Champion?
