After a while hemming and hawing and a few false starts, I figured my submission out. I just had to find the right thing in Faerun to build from.
Raziah is an Inquisitor of Torm. I'm using the Ravener Hunter archetype for free, and adding Sanctified Slayer using the regular rules.
She was taken into the church and raised after her parents both offered up their souls to be siphoned from their bodies to empower Torm so he could defeat and kill Bane. Raziah and her young brother are among the many children left behind by the event, the Martyris Progeny.
Her brother Joris adapted well to the new situation and is now a priest. Raziah not so much. She can't bring herself to leave Torm's church so she works alone undercover, mostly in The Vast and The Dalelands. She looks for potential trouble brewing and emerging threats, reporting back to her higher ups in the city of Tantras by letter.
I have the build and mechanics done, still working on backstory and gear. I should be able to finish up tomorrow.
