So I look up a pretty prominent Star Wars guild and message one of their council and ask them to poll the same question and get back to me in a week. They do, and naturally the fuckin geeks said "Death Star".

You are not going to pass a skillcheck against a rip current once it has you.

Waves will not bow to your physical prowess no matter how impressive.

Shock does not care that you used to be on your school swim team.

If you hit your head, being good at swimming isn't going to turn you face-up while you're unconscious.

And I get it. Bolaire is the one we know hates Thjazi and thinks the worst of him (and the one a lot of people seem to be liking less and less versus liking Murray more and more), so it's easy to say "hah!" to him and think he's the one to prove wrong. But if they wanted those slanderous theories to stop, they had to get Murray set straight. Bolaire didn't much offer up his bad opinions of Thjazi until someone said something that prompted him to add to it. Murray kept cooking on those theories.

Hell, I think Bolaire dropped at least "working with the Sundered Houses" after the Knife & Palette Paints and learning about the Cloak, seeing as the Cloak accounts for why Thjazi and the Sundered Houses were after the same things: the Cloak watches the Houses closely to try and swoop in and get those assets for themselves.

He still seems to be on questioning the ritual, but given the caution we saw with a simple de-petrifying of Cyd, I'm inclined to think at this point it's just a professional caution of unknown/unpredictable magic. Especially a ritual in a theatre and on that large scale, given Bolaire's not-dissimilar first acts/original purpose. Plus none of the PCs or people they have access to currently designed the ritual, so they don't even know for sure what the specifics of what it does are, just theories, so again, professional caution doesn't strike me as unwarranted from Bolaire.

Murray is the one who threw out, rather apropos of nothing, that Thjazi might pop back up as a god because of the ritual since that's what a Sundered House would want for themself and she thinks Thjazi was stealing one of their rituals to do before them here. Bolaire wasn't even there for that one.
