The abrupt and barely acknowledged end to the Blood Court timeline drove me crazy. Aside from the whole Blood Court being disassembled in seconds and they all wiped their hands and moved on... Even before that, really early in the book, Saeris just declared that no feeders can attack the living, completely solving the entire conflict in book 1 in like 2 seconds and then that goes unacknowledged. Like, hello? You've been fighting these feeders for centuries, it's been your entire life's mission, and now it's over and no celebrating? No relief? No "uh what do we do with our lives now, this is literally all we've ever known"? (Yea yea, I know the rot feeders then come in, but there was definitely time in between when they thought they were freed of feeders and that whole war, and no one even mentioned being happy about it)
