Yeah who'd be such a spoilsport as to refuse them permission? ...and who even has the authority, no one's claimed the Moon yet, it can be theirs if they want.

Well there's the Outer Space Treaty.

He is not a signatory to that.

That is indeed true! The various Earth governments might not be too thrilled about this anyway, but, "Arcologies!"

Yeah!!!!!!!! He will do such nice plants and sufficiently pretty buildings and tell Hero "I did this on Cube's Earth's Moon when Elves had to live there to help with Yeerk sorting."

"Yeerk sorting?"

"Yeerks are these parasitic aliens that crawl into your head through your ear canal and control you. They'd conquered a bunch of species that way and they tried to go after Earth and Earth stopped them and then when the peal found that dimension they got the whole empire to surrender in a week and then we needed to sort billions of Yeerks by how likely they were to respect that they can only take consenting hosts now."

"...eek. That sounds terrible. And I think I remember hearing about a master who could do that in Namibia."

"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."
