"Well. Thank you." 

And Leareth gets right to work following the tutorial for his new brain computer. It's pretty neat. 

"Do you want one too?" Cam asks Vanyel.

"Yes, please." It looks like it's confirmed safe and it sounds pretty useful. And fascinating. 

Computer for him too. The tutorial wants them to attempt to do various computer operations with their mind, so the computer can learn what it's like when they try to do things with their minds and in the future be able to respond to that.

What a clever concept! Leareth cheerfully tries the various computer operations with his mind, until the tutorial is done and he can start using his computer for real. 

It's pretty great!!! 

Lissa wants one too! She's not as much of a reader, but she wouldn't want to be left out. It should be easier since she's not a mage. 

It does not require brainscans! Voilà, computer.

This is amaaaaazing! Lissa thinks that Milliways is great and Cam is great. She does her tutorial a little impatiently. 

...Can the computer make music. That would be pretty cool. 

"It can play recorded music - yours has a basic essentials package curated by a Librarian of Hell, I'm not sure what's in it actually - and you can also teach it to play chiptones, here's the peripheral for it, go to 'peripherals' and pick 'chiptones, Serenade 4' since the model of this one is called a Serenade 4, and you can get it to play tones in various instrument voices, some people can do chords but it's harder."

"What, exactly, is a Librarian of Hell?" 

"Someone who works on curating and sorting and collating and organizing all the information and creative works ever in my origin worldset."

"Huh! That must be an awful lot to sort!" 

"They're very busy."

"I bet!" And Lissa wanders off to play with her new music collection. 

The computer and reading material are enough to keep Vanyel well-occupied until two days later, when he prods Cam. "I can do the Gate practice again today, right?" 

"If Leareth's available, yes."

Leareth can be extracted from his reading to try some tiny embroidery-hoop Gates, after Vanyel's beta blockers have kicked in, starting half a mile off but gradually drawing closer. 

This time Leareth gets to just a hundred yards away before it starts to hurt! And it's a gradual, warning pain that stops immediately when Leareth drops the Gate. 

He's tempted to try it again, but Yfandes tells him very firmly not to push it too hard today. 

Cam agrees with her.

Then he can go back to reading. He can't help Leareth with the hands-on part of spell research, but he can read up on various Gate theories from across history and collect notes for Leareth to work from. 

Leareth works from them. He goes out in the backyard when he wants to cast actual practice Gates. 

A week in, he's pretty sure he'll be able to pick out just the 'search' aspect of a Gate, and point it at an arbitrary target. He's not sure yet whether in practice this will behave like a regular Gate-destination or turn the whole thing into a summoning spell, or whether both versions are possible. The latter would certainly be more convenient for them. 

On his third session, Vanyel can handle a Gate at fifty yards. 

"You're doing great," Cam tells him.

"I think it'd at least hurt me much less, now, if we wanted to Gate to Endorë and get started–"
