[X] Sacrifice Inaan. In the end, the dragon was too full of spite to live in an imperfect world. She will take Silk-and-Eye as her new consort and leaves Cahzor behind. [Will end the story.]
I don't want the quest to end, but - this is the victory condition, assuming the options and text presented are honest (and Rena is supposed to be good versus Fae, so I assume it is).
Hot boytoy? Check.
Ticket out of this shithole? Check.
Path to power? Check.
Protection from demon lord? Check, and this is a hard box to check.
This is everything Rena has wanted since the quest started, in one handsome, well-endowed package. And the cost is a few mortals. She has spent lives for less, not just in her backstory but in the actions the voters chose for her.
Hell, considering what the demon lord might do after he kills Rena, this might even be the altruistic choice.
C'mon. What did Time and Causality ever do for us?
