"And from Abaddon there is another demon - we actually live in the same place when we're not on summon, turns out, there is at least one other demons world but it has kangaroo lizard daeva instead of human-looking ones - and ten Fëanáros aforementioned and ten of Curufinwë in with them - and Maitimo -"

Oh no oh no that rather changes the prospects for peaceably sitting around a few centuries until he can return to his Maitimo with the means to win the war - it's possible an alternate universe Maitimo will respect his Maitimo's claim but not likely, not if it's centuries - 

- this crosses his face as strong surprise, not as anything negative, he knows better than to look upset -

"...uh, the Singularity one of him and one of you have major drama, but this one is less drama-ful? I don't know about yours?"

Drama is an interesting word. Rather clearly communicates 'I don't want to be bothered with it', which is a reasonable preference, all things considered... or at least a common one... "I suppose I shall have to meet him," he murmurs. "I'm sure we'll get along fine."

"...okay. And a Tyelcormo and a Huan. They keep talking about getting Macalaurë for morale and the other demon, her name's Edie, has a twin and wants her, but they haven't done those yet."

"Getting?"

"Uh, before I explain that I will have to explain Information Security With Demons Around 101."

So he does that.

At which point it quickly transpires that he does not know what a computer is.

"You don't have computers?"

"No?"

"Do you have electricity."

"...no."

"Indoor plumbing?"

"...yes, what are the other two, magic? Technology?"

"Technology."

"Both of the other Ardas had them?"

"Yeah. Uh. Did you grow up in Valinor and then travel to Endorë."

"Yes."

"How. Did you get there."

"Ships?"

"What kind of ships."

He sends the mental image. Big white swanships, coerced out of Olwë's hands he-didn't-actually-ask-Maitimo how, but it was very clean, however it happened.

"The kind that go on water. I see. That makes no sense at all but okay. ...Wait how did you do that."

"...osanwë? Do the other - mes - not have that, it's universal among Elves on my Arda..."

"They have that but it doesn't work on me..."
