Interdimensional transit: next up. Fast as she can.
She evacuates, if you can call it that when she brings all the buildings and the walls. She plunks them on a nice grassy plain.
And she pops north again and clears out the bomb assembly site and puts it upwind of the bomb test zone, and goes to Mithrim, "Morgoth's alive and taking form as a fallout cloud permission to wreck your plumbing relocating this whole shebang to another continent?"
It was us, just didn't kill him. Taking the lake would be kind of a disaster, but she hops into the air for a good goggle-enhanced view of everything else, picks them up, puts them near a different lake which is not shaped right but should at least serve generic lake-related purposes.
And she pops into Doriath. Melian, we leveled Angband but Morgoth's still alive and now he's pissed off. Can you hold or do you want me to move this entire forest to another continent for you?
Brithombar? Dwarves? Miscellaneous Thindarin populations? Orc colony?
She pops back to New Himring and reports on who she has put. Missing anybody you know about?
Well, the place is radioactive and very hot, right now, and I can't target to land near the Silmarils themselves to avoid being irradiated, so I'd be betting on my healing to work faster than the environmental hazard. Invent me a rad suit if you want me to get them. What I meant is are there any other settlements I have not yet evacuated that you know about besides Doriath which is staying put.
Loki pops around to ask other evacuees if they know of anybody else she ought to get.
She goes looking, keeping an eye on the cloud.
