It's hours later when Loki and Cam bring Bella, Elspeth, and Jake to Vanda Nossëo and make it known to whom it may concern that they're here, news is available about the newest Arda and its adjacent world-with-a-Bell-in-it, and someone needs to relay Elspeth the spell symbols because Golden can't let mind-affecting powers including osanwë through her shield unless she trusts whoever is using them. And Elspeth wants to know if the non-evil Maitimo who was so upset is okay now.
"It was a favored tactic of the Enemy. He can't directly control minds but he can coerce oaths or he can tamper with memories at will and then run you through scenarios until he gets a result he likes, and it often came out to nearly the same."
"Yes, I've received the summary of who this template is and why we do not approve of him. Witches occasionally can directly control minds. Chelsea at least is dead."
"Loki, can your magic do invulnerability to mind control? If we're going to be wading unsuspectingly into dimensions where some people have it casually - it would be a disaster if something got you - I've asked my father also, obviously -"
"I could rig something up - spellbinders will have something faster if they can have anything at all, though."
"I can extend my shield. It's not effortlessly sustainable, but it's doable for scouting intervals with people I like."
"I think my father's pretty close to unbounded working memory for the Marlatians, so perhaps that can be a stopgap until they're omnipotent six times a day."
"If only the Tesseract would cheer up it could assess people for potential to get along with the Mind Stone but I have no idea how long it's going to take it to get over the existence of locations it can't reach."
"It's the Mind Stone. It could easily choose an expression of displeasure that was not destroying the rock its handler stood on. I'm not even positive it couldn't backpropagate effects to other forks of the same person."
"Yeah, maybe. But it could be very hard to detect some classes of failure if it felt like being subtle. The Mind Stone is, itself, entirely capable of mind control."
"I wasn't volunteering. But if we ever urgently have need of it it seems useful to have a method for finding a handler in advance."
"Fair enough. The same method would work for finding someone who could handle any of the others, though, and except Soul they'd probably all go for nonsubtle destruction, and some of them can work a little sideways - the Aether is not really designed for free-will-related applications."
"Didn't think so. Maybe I'll ask my Space counterpart to assemble some people who the stones might like, whose forks can be temporarily put in Revelation or something, and who we'd trust wielding one if it happened to be a good match."
"We also still don't know if they beat daeva indestructibility. Should really get around to testing that."
"Are we expecting that if the Tesseract can't pull your wings off then the mind stone can't tamper with your head?"
"No, but we are expecting that if the Tesseract can pull my wings off then the mind stone can tamper with my head."
"I will eagerly await the outcome of that experiment, then.
...if summoners from a non-adjacent world die in a world adjacent to the daeva realms, do they get your afterlife, has anyone checked?"
