"It's really important I not get magicked. I can't get Yeerks because I'm indestructible but that might not do anything against powers."

"Yeah, I bet the PRT brains are gonna think of it but maybe tomorrow we should suggest some more thorough power testing—the teleportation still makes you pretty hard to get ahold of and—wait indestructibility?"

"Demons are indestructible, yeah...Boots'd be way more worried about me if I could die."

"How's that work, though?"

"Nothing can really hurt me? Like, if you stab me I'll get a cut, a small one. If I throw myself into a sun during a tantrum - I do that sometimes - I'll get burns, but not bad ones."

"I get more envious of your magic by the minute—and that makes it even more terrifying if—I hope you forgive that I thought that in the worst case we'd kill you if you got controlled or something and then we'd just return to ground zero—"

"That would obviously be the thing to do, my peal could even resurrect me later - stun weapons work fine on me -"

"Stun weapons sometimes fail to work on people under mind control powers—"

"Then you would have a problem. Unless oaths stick."

"Yeah..." But in any case he wants to return to the topic of arcologies and cool future tech.

And he can chatter all night about that. This is based off Cube but Cube's are based off Revelation, which has native summoning and so did a lot more space travel than is feasible for most Earths.

This is so! Much!! Fun!!!!!!

And eventually it is morning in Chicago.

Pop! They are back in his house in Chicago.

Where a fairly distraught Legend is waiting. "Are you," he asks as soon as they appear, "responsible for what has been going on on the Moon?"

"...yeah? It has arcologies now. In case people want to live there."

He nods, relays this into his comm, then releases a relieved breath. "The United States government—and several others, and the PRT and the Protectorate and the Suits—are going insane over that, they thought it could be some tinker threatening the Earth or something worse."

"If you write 'letter to Epic' on a piece of paper I'll see it within an hour, I make 'all the letters written to me' and I can get them that way."

"That—would have been a good idea, yes," says Legend, who has known it was Epic all along but has to play this part and it's kinda terrible but okay, "but in any case, starting large-scale projects on visible celestial bodies without warning anyone can frighten people really bad, there was even talk about how this could be a Russian ploy, or an American ploy, depending on who you ask." And he gives Hero a pointed look, since, well, Hero should know better.

Hero manages to look appropriately sheepish despite the mask.

"Sorry. We went to another galaxy first to check if powers still work there. They do."

That they failed to catch.

"Why were you checking that?"

"Containment of prisoners. Some magic's local to a planet, some's local to a dimension, some has an adjacency limit - if we had somewhere where powers don't work we could just build a nice place for parahumans who can't be deterred from murdering people there. Different dimension still might work but different galaxy doesn't."

"—well have you tested a different dimension? That could be potentially very useful."

"I haven't, jumping dimensions at random is dangerous in case the local magic system interacts badly with something you've got, there's a small chance I wouldn't come back. If you have anyone who can breathe in vacuum and who wants to try I can tell them the risks and then they can jump and write a note saying it's safe and I can go and get them."

"I technically could, and so could Eidolon. Library of Alexandria could hold her breath for long enough and survive in a vacuum."
