Downstairs the door opens and in walks a six year old girl with a weird animal.
Sauron's got a deadman switch. I had a civil conversation with an alternate universe version of you and thought I might as well try asking you if you know what's up with that.
He set it up while they were negotiating over oath minutiae, I think. It's some kinda plague.
How charming. Would it be inordinately difficult for the Valar to clean up without his help in some way?
Uh, apparently our assessments of the capabilities and interventionist inclinations of the Valar were a bit off so fuck if I know.
Nobody's been taking any precautions to keep it from getting all over the place and it doesn't seem to have harmed anyone in various alternate universes. Would his magic hold like that or should I assume there's some hidden decontamination feature of my transit?
Might hold like that. I don't know if his death would trigger it in other universes, though.
So the easiest way would be to have some place on Endorë he's keeping sealed with magic, lets another biological out that interacts with the first one. But that's easy to handle, so if he expected you to pull this shit - and I don't think he was expecting you to pull this shit, but who knows - he might be magicking all of them to, say, have limits on how much they multiply. Things we've done magic to stop when we die.
