The Valar announce that they've done as much as they can in Singularity (they can't bring back peoples' babies in that critical period either, but they can get them earlier versions) and are setting up portals between there and Sanity as soon as they are confident they've cleaned up the plague. A bunch of Elf architects have this wild idea for a fivedimensional city where alternating intersections are interdimensional portals between various Valinors and they get eagerly to setting it up.
"One of our friends may come by later who'd want to meet Rúmil but she's not a priority for us today."
"I am sure my mother would be delighted to give you a ride back to her home, if that's convenient. Mother, will you see to it they have a way to get back to the palace eventually, I have apartments for them here -"
"Sure." She rummages in her desk, pulls out two pretty bracelet-things. "These'll pretend to be chips for you. They have money, they'll let you into your rooms...Timothy, you're in the left wing, third floor, Cam I know you said you didn't need to sleep but I got you a room anyway, right wing, second floor."
"So far apart! We're not telepathic, what if we wanted to talk amongst ourselves and didn't have other technological solutions for that." He puts on a bracelet.
"I do apologize! Given more advance notice I could wrangle closer ones. I take it you do have other technological solutions for that?"
"Yeah, we have computers. Mine's fancier, it requires brain surgery." He waves it around a bit; he has been using it to look up poems and such all along.
"Uh, do you want me to explain the computation, the projector, the underlying knowledge base I've been searching, the messaging protocol between the computers, the brain interface, or something else - I know the answer is 'all of them' where do you want me to start."
"Okay! Comp sci 101!" And he starts with logic gates and goes from there as they head to her house.
She's a terrible driver; some of this might be attributable to the fascinating conversation. They get to the house. "Girls! Time-travellers!"
"That's a new one." She is balancing two tiny babies on the back of her giant dog. "Hi, time-travellers!"
"Elsewhen," says Cam. He carefully does not look at the giant dog. He had forgotten there was going to be a giant dog.
She releases the babies. The babies touch the wings. The babies are delighted about the wings and say so with high-pitched sounds that mostly only their siblings can interpret. Tyelcormë combs Huan's hair back flat. "Hi!"
