"He doesn't have like a reason or anything?"

"He hates the divine plan so he wants to provoke God into intervening."

"...okay..."

"Yeah. Anyway. Elves and Valar can swear things, bindingly. Melkor offers Cam a deal where if Cam feeds Valinor into a black hole Melkor'll stop being evil."

"What's Valinor?"

"The planet we'd all left from."

"You were there too?"

"No, sorry, my alternate universe version."

"Okay. So did he get everybody off the planet?"

"No, the condition was that he not warn them at all. He had a way to resurrect the chipped ones."

"Was that most of them?"

"The majority, yeah."

"...and then the evil god stopped being evil."

"Yup. And the alternate universe version of me figured if there were six dimensions there had to be more and invented interdimensional transit and they went looking for a way to resurrect the rest of them."

"Did that work?"

"Yep. Not right away but they got them all back. And killed the evil god even though he was sworn to be good."

"...like actually good or just not doing evil."

"Not doing any evil. They had a really really long careful list."

"Okay."

"Anyway. They jumped dimensions and they landed in Hex. In Hex people are born with spirit animals, that they can make into real physical animals. And the animals are people. And if you do that you're a spellbinder and you can cast spells, six a day. 

And the first people they met were alternate universe versions of themselves. And that's how we learned they exist."

"Do you have a spirit animal?"

"My Hex alt does, yeah. He's really into spirit animal languages, he speaks like thirty and he's trying to figure out where they come from."

"Why do you say 'I' and 'we' when you mean other people?"

"I mean, they're alternate universe mes."

"Does your native language do that or something, use 'I' to mean 'anybody who is a me'?"
