Leareth is lying in a stone room, and nothing in particular is happening right now, and he is mostly succeeding at not having any thoughts. It's a fine moment. He is not, literally this second, being tortured. This is not useful at all for predicting what the next moment is going to be like, of course, or for whether 'quiet stone room' has any particular resemblance to reality, but Leareth has gotten pretty good at not being curious.
When Leareth wakes up, alone with everyone gone, he doesn't feel a lot better, but something does feel different. It's a little easier to keep his train of thought pointed at something.
He gets up and walks around a bit, and notices that he's sort of vaguely dissatisfied with the room, and wonders why. He's really out of the habit of having preferences about his environment, much less doing anything to achieve them, but since he's not in Angband anymore, maybe it makes sense to change that.
The room isn't ugly by human standards, but he misses Tirion, and things being pretty the way Quendi make them in general. It's noticeably an infirmary room, even though the bed is a pretty comfortable one rather than the usual cot, and they brought in a desk for him; it's very impersonal. He would prefer a different room, he thinks.
What else does he have preferences about? He's still tired all the time and has trouble concentrating for long; he hates that. He should ask if Bella can do something about it. Maybe she can do something about nightmares so he gets more solid sleep - he thinks someone else might've mentioned that to him at some point but he can't remember now. (His memory is terrible right now, but he thinks it's mostly because he isn't paying attention to things, due to being exhausted.) There are probably other things he wants to be different, but that's a reasonable start.
The next time Bella is back, he has a list.
Well then, she should go down the list and see what she can do. "Yeah, I can block nightmares. It won't stick, but I can ask Nayoki in and see if she can get something more persistent, if you like?"
Nayoki? I'm going to do a nightmare block for the older Leareth, but it won't last long if I do it by myself and was wondering if you could watch and maybe supplement.
:Of course! That sounds very interesting to watch. I will be right there:
She arrives about three minutes later.
Nayoki things that is really fascinating, she's not sure she could do it on her own but she can definitely pin it in there more firmly, and keep an eye on it, it won't last forever but she'd guess six months, maybe a year?
Do you want her to watch the core memory work in case she can help with that?
"He says you can watch the rest of what I'm doing too." So she calls in local Leareth and tells Nayoki how to interrupt and resumes work on that.
Angband Leareth is less stressed about it this time, and also slightly better at focusing, and makes it through an entire chapter about planting flowers from bulbs.
It shows up really clearly in Nayoki's Sight what Bella's doing, actually! Nayoki can bounce it to her when she's taking a break and it won't distract her. The degree of progress is a lot more evident.
It's less clear to Nayoki that she can help? It's a more precise level of detail work than she could do herself without, oh, another twenty years of refining her Sight and Gift-control just on that kind of thing, and Bella's not doing it to be temporary, so fixing it in place more isn't necessary. She can make the not-yet-fixed parts of Leareth's mind a bit more malleable, Mindhealing can do that without changing anything directly, but it's unclear if that'd make things easier or harder for Bella.
It might help with the middle stage of each section, if you can do it on and off pretty easily?
She can do it on and off easily, and with reasonable precision on where since she's practiced that; it'll take a few seconds for the change to settle. She's happy to try it for the next one if Bella tells her when, and can stop right away if it's bad.
