Which he does, with the efforts of a very confused staff.

And Sadai goes to the appropriate pole.

It is very very cold and nothing grows here. It's also dark.

He is completely unbothered by the cold and can definitely see in the dark. He runs the place's perimetre. How big is it?

Eighty thousand square miles (two hundred thirty thousand square kilometers).

...this will take a while. He gets to work.

Olvala decides the test project is a success and drives the rest of its reds out of their cities with much bloodshed. Newly trained purples clean up the bodies.

"—Aitim what—"

"They haven't bothered your mining town, this was the rest of their districts."

"I am not remotely relieved by this—"

"They didn't announce it in advance lest the reds riot. They're not committed to killing them or anything, just want them gone - the sooner we can go public about having somewhere to put them, the better -"

"Have you found the purples -"

"Yeah, I have some people you can sell things to. They think I'm fencing stolen goods but that's all right."

"—I'll be done tomorrow."

He hangs up. He does not speed up because he's already been doing this at top speed, that was his previous prediction anyway, but—

He texts the reds from the mining town.

Are you safe? I didn't know they'd do that, I'm almost done here but I can go get you if you need me to.

They haven't come here yet.

Some of us were in other towns but we told them to come here so those are okay if they made it this far.

I'll be done tomorrow and I have the means to set up the actual infrastructure now but that might still take a while. I'm going as fast as I can.

The stuff we have here can keep us for a while if they don't come.

Okay. If I hear anything I'll tell you, but even if they come you all should be much safer. I'm so sorry about this, I didn't think...

No reply.

He works.

Isel asks Aitim if there is a plan. Then she writes Anitam's reds to tell them that Olvala reds are all going to be relocated to the poles, after they hear from them about it maybe some people will believe it and go check it out?

Uh, they don't speak any Olvalan most of them but machine translation to the rescue, they guess? Tell them to take lots of pictures?

Will do. 

He sends Sadai materials lists.

Sadai can produce some of that stuff while he works but he won't be able to catch a plane if he does it at scale. But soon he's completely done, and then he spends an immense quantity of lifeforce and—

—the temperature stabilises, then climbs. The stars become—not exactly brighter but they're better at illuminating. Cutting winds die down and snow starts to slowly melt. Various nutrients appear in the soil, ready to be used, and he speeds that along by generating live grass and planting it everywhere—that's comparatively much faster. Within an hour of finishing the spell, that pocket of land looks—not exactly normal, the lighting effect and the surrounding snow makes it a bit surreal, but other than that perfectly livable. He takes pictures.

And he has a plane to catch.
