AAAHHHH! I was just thinking of Mass Effect, actually! I'm so glad you know about that game! I was imagining that yeah, while similar to indoctrination, the actual sounds and images she might hear and see would be like using the Prothean beacons, where it's a bunch of horrific noises and clips. I think she would be less deluded than Saren was, and would be able to identify the fine lines and what is and isn't normal for her, but still struggling to resist what Molag wants from her. I reread it and it looked as though that's exactly where I was going with it, but in the backstory, possession came out from the left field. That may be one of the remnants of her first character sheet.

We can shake and call it a deal on Conjuration. It'd be reasonable to expect a priestess of Kynereth to learn that school in order to summon nature based familiars and banish daedra. That also means I don't have to carry that scroll around.

There actually isn't much out there about the purges, it's somewhat obscure. You're right that Valenwood probably wouldn't side with them if the Thalmor consistently slaughtered anyone they didn't like. Apparently it was just small enough that the Silvenar and Green Lady, for some reason, would let them get away with it. Perhaps because their alliance was too important. Without them, the empire would try to rule them and they didn't want that either. I just know they existed, but anything more than that is fan theory.

I'll make the changes when I can. Thanks for the help! I'm looking forward to what gcold has to say.
