"Tireh asked about taking evil Fëanor to meet his family and I had to know what the fuck had happened such that whether that was a good idea was in question."
"Midnight clearly does have some coping skills the rest of us lack but I am nonetheless not going to ask after or adopt them."
"- I guess if it works."
"Maybe the genderflipping helps but I have a hard time seeing any of the terrible things my alts do as - anything other than very distant disasters that I can fathom having happened under completely different circumstances but - so different that I only sort of recognize myself -"
"I'm also not dating my cousin, I bet that helps."
"How's the new planetary governor settling in -"
Things to check: can sorcery teleport an immaterial Maia? (No.) Can Tireh teleport an immaterial Maia? (Yes.) If an immaterial Maia is tipped off and leaps to a world the peal hasn't discovered yet, can they be summoned back to Warp from there - that one works on Olórin, turns out, but they're not confident it will work on Sauron because he has the antidivination/anti-magical-finding up. Can they stop Sauron from himself teleporting (Gandalf and Olórin are still working on it. Either the work requires occasional explosions or they're just having a lot of fun.)
Do Edda and Warp have any neighbors in common such that they can avoid having to teleport Sauron as far (they set some teleporters to jumping for new Edda neighbors).
Can Tireh incorporate her notes into her indestructibility so it's less easy to separate them from her? (Tattoos work but don't have anywhere near the needed surface area.) Are there other ways to make sure Sauron can't separate Tireh from her notes? (Spellbinders are working on it.)
If they intend to kill Sauron who else goes blank in Sibyl's precognition? (can't check that until they're ready with everything else).
When they're ready with the teleport blocker and ultraminiature tattooing and everything else, she can't see reports about it, but can see all-clears from uninvolved personnel on standby in passthrough worlds.
That limits the scope of the catastrophe, at least.
"If only we could drag him out of Materia as easily. I'll assign a couple people to keeping an eye on the planet he was, ah, involved with - track down what he was doing and notice any kind of delayed-reaction disaster -"
