"- I, uh, think our concrete demands are that we don't want him using our population for blood-sacrifice, but that's - I think he wasn't going to be ready to actually do that for a few decades anyway."
...Vanyel takes another deep breath. "...And, uh, I'm - not, actually, sure that the recent - things that happened - were his doing.

That's the - it's in the core territory of the Star-Eyed Goddess. I'm pretty sure he's claimed before that he couldn't operate without interference from Her in the Pelagirs."
