"So," says Bella to Rúmil one afternoon, "a few weeks ago I told myself that if in a few weeks I had not come up with an actually good way to bring up a thing I would just mention it anyway on the grounds that if it came up somehow later and I had not done so that would be weird."
Then that's likeliest what he was looking for - can the demons check if he's been to our planets -
Probably not the priority, then.
If anything happens I would just prefer not to remember it. Just so you know.
Okay. Do you want to know about it if you don't remember something?
And he won't run out of mana and he might not even be material enough for it to be theoretically possible to hop him to Space even if he somehow couldn't react to trying it, yeah.
Now that we have Sibyl it'd be safe to try teleporting whole star systems, seeing if they keep momentum okay -
Check messages - They don't. I'm not actually sure he'd come along if he happened to be immaterial anyway, I'll go check that with Olórin.
"Yeah, we can go find an asteroid and put it in Revelation and see if you go with it."
He does, not that this helps while the Sauron is on an inhabited planet.
Wonder if the Valar could make themselves useful here somehow.
Elspeth travels to Telperion and hey Valar remember how you were gonna arrest Sauron well he went to Warp.
That does not really surprise Elspeth, for reasons. Anyway they could maybe help arrest him in Warp without Eru's assistance?
Well that's worrying. How would the Valar go about trying it?
Uh - given enough time they could set up somewhere else the way they're set up in Valinor and then tell wizardry to stop working the way they broke the necklaces. But they don't want to have too many of them away, lest Sauron attack.
(They shut down wizardry in Valinor, as a precaution.)
They could try talking to him and asking him to surrender?
...they should probably announce the wizardry shutdown so people know why they suddenly have to go back to doing their laundry by hand. Also time might not be infinitely available, especially time-while-Sauron-is-on-this-one-planet.
