"There is," he says to the demon, "a way to travel between worlds without being summoned. I will trade you the knowledge of how to make it for three of them and some help identifying a habitable planet in our new dimension."
Taliar is not especially mopey. He does miss his husband, but he's not sure that Maitimo can't hear him, so it's not as bad as it could be. He'll be very glad to get back to him when he's flung his healing aura over all relevant planets, though.
He finishes flickering through all the stops between Nuime and Warp.
"Come in," says a voice from inside the office he's landed outside of.
He goes in.
"Hi. Elaneth-imire Taliar, nice to meet you, please throw me at some planets."
"Certainly." She has a list ready and a map with pictures of the stopoff points.
"Thanks!"
Off he goes. Anyone within several astronomical units of a target planet will find themselves extremely healed.
It takes him an hour or so to get through them.
Then he returns to the hall outside T'Mir's office.
There is a brief delay this time and then he is again invited in.
"Did anyone mention to you the possibility of de-radiating Cube's Earth?"
"I can go throw my healing aura at it and see if that helps. If not, my soul will probably branch something for it pretty quick."
He goes to Cube. He floods their Earth with warm golden light. He can't tell if it's working, so he leaves it on for a minute - another minute - he probably should've asked how and whether and how fast they can check if it's working -
He can respond by osanwe, though. That's me! Is it working?
All right, I'll keep it up.
He does that. The improvement accelerates. At this rate, it looks like it's going to be all done in fifteen minutes.
<On track to be as not-radioactive as it used to be in a quarter hour.>
<All set. Thanks so much, do you care how I explain this to the media?>
You're very welcome, and if they know about the multiverse I'd prefer to be personally credited but if they don't you can say whatever.
<Not common knowledge yet; it's just known that I have powerful allies who give me stuff.>
Well then, I suppose a powerful ally has just given you some stuff. And I think that's the last thing I can accomplish for you with just the powers I've got, so I guess I'll go home now, unless you've come up with another thing in the last fifteen minutes—?
