"I am wholeheartedly in agreement. That is a harder problem than any of the other ones confronting us, though."

"True."

"The thing with the most pressing time limit is immortality, if Bella thinks she can do that then everything else it's more important to do right than to do fast."

"I don't have a principled reason to believe I can't do it."

"Well, we'll keep working on the other avenues too. 

This isn't really a proper greeting at all, I'm sorry. We usually have Nelyo for that and he can't get off work until next week."

"It's okay," Bella assures him.

"We have rooms for you to stay in? We have computers and explanations of computers and so forth."

"I've got some very preliminary work on computer to crystal ball interfacing - I think probably the top immediate priority is to get everybody doing introductory wizardry but I'm not sure if the efficiency boost from being able to send notes from the ball to the computers is enough to warrant doing that first - I guess Rúmil or Fëanáro are just as qualified to walk you through the cantrip scrolls -"

"That sounds reasonable. We can start on wizardry right now if one of the two of you wants to walk us through it -"

"Where's me, I want to meet him -"

"Downstairs working. I'm sure he'll come learn wizardry."

Bella unpacks the scrolls - teekay isn't scary and nobody will know it goes with telepathy and read into that, right? - and wafts them to Fëanáro.

Nobody seems scared. The adult Fëanáro emerges, blinks at Rúmil, and then demands to be taught wizardry. And everyone gets to work.

At some point they get a tour of the place. Their rooms are stunningly pretty and look out on the mountains. There's a bank of computers downstairs. Fëanor doesn't sleep any more often than his younger version - less often, if anything - and rolls his eyes when told this will slow him at magic. They mostly grow and hunt their own food because it's 'less complicated'. They all take to magic quite delightedly. 

And with all this science to talk about three days go by before Fëanáro mentions that Bella saved Miriel.

"How?"

"She was sad because she was trying to not act on an oath and it drains away your caring about things."

"An oath?"

"Yeah she accidentally swore something when she was having me that made her have to kill me but she never did, just - stopped wanting anything else, slowly -"

"How was Bella able to fix that?"

"She made it so she couldn't! She can do that, and then oaths don't bother you."

"With wizardry?"

"No, with therapy. Bella's a subtle artist!"

"...subtle artistry's not transferable," Bella murmurs.

"What is it?"

"Subtle arts are a technically-non-magic set of powers people can have in Materia, of which the most common is telepathy, followed by telekinesis and pyrokinesis, of which the most common civilian application is therapy, it's what I went to college for."

"Well. If it worked."
