After Cam's magic but still basically human boyfriend has fallen asleep and Cam finds he is not tired enough to do the same, Cam goes downstairs.
And that is about as much non-technical non-linguistic discussion as one can get out of a room full of Fëanors. One of them makes a model of a flat planet, tampers with the gravity, demands to know if his alt has measured the acceleration of a falling object...
The Nerdanels exchange looks that are either deeply meaningful or accompanied by deeply meaningful osanwë conversation.
"Oh, yes, can you make blessing rings? We were told they were magic but the other kind of Elf has blessing chips so maybe they're just very advanced technology that the Valar misled us about..."
How about that one then. He gets a ring. "It might not work, that happens if I try to make a wand, how do you check?"
"They're mostly pretty subtle - grace or warmth or balance - I suppose some people have ones that just glow, and you could try making one of those?"
The new Fëanáro and Nerdanel look at each other and then start bouncing up and down excitedly. "We've got magic, we've got magic, we've got magic and a time-stopping bar -"
"Once Maitimo's grown up we can become omnipotent!"
"I love you!"
"I love you!"
The chip Elves are very uncomfortable.
"You use osanwë to write instructions to a piece of metal. Very very detailed instructions, and anything complicated is excruciatingly slow, computers as they were explained to us are fairly analogous only imagine you are directly inscribing all the ones and zeros with your mind. I do not think there are any principled limitations on what it can do - you could certainly become as powerful as a Vala -"
"Betcha we can do it in two thousand, with the computers to help, and inventing some things for memory and intelligence that will help us invent more complicated things. The children can wait two thousand years, that's not really so long and it'd be unfair to have them when we're not omnipotent, now that we know we might need to be..."
"He'd miss Maitimo's whole childhood - we could close the door with Maitimo on the other side, I suppose -"
