Ugh. 

He backs off. :Bella? I am trying to find the memories of him doing magic, and having trouble getting to that instead of awful torture memories. He is understandably quite stressed by this. Is it something your arts are better at?: 

Uh, if he helps it's easy, if he doesn't help I might or might not be better at it? If I can find a couple of memories of him doing magic I can find the rest, so maybe you could prompt me with some that would match and then I can find more recent ones.

:He is not helping. I did not actually explain what I am looking for or why, though, it seems that explaining more things is mostly going to be bad. I can find a memory that both of us should have, sure: 

He'll have to dig around for something salient enough that he would definitely recall it decades later; permanent Gate installation in the facility where he first recruited Nayoki, that'll do. 

With some rummaging she can find the corresponding memories in Angband Leareth and do her own signposting of magic memories, slightly laboriously, and then try to find recent ones.

How recent? There are lots in Arda, before his capture; after that it's much harder to find anything.

The memories of Gating are there. It doesn't seem like there's anything else. 

I found the Gates, I think that's it.

Leareth checks himself as well. :I see. Thank you: 

:I am stopping now: he tells the other Leareth, and backs out of his mind. He gets up and leaves the room. 

:Now maybe we can leave him alone and let things be very boring for a week?: he sends to Bella. :That was the most time sensitive piece: 

I think so, yeah. I'll call Other Vanyel back tomorrow and let him know.

:Thank you: 

Leareth checks in with the Healers, makes sure someone is on duty to keep an eye on Angband Leareth from a distance, reminds them about making sure he eats and drinks at reasonable intervals (they don't really need reminding of this, they're Healers, but it's possible he's fussing because he can't think of anything actually useful to do.) 

He lies and drifts and eats when forced to do so. 

Bella scrolls her interplanar transit and stares at it till there's a copy in her Valinor for Rúmil and Fëanáro to look over. They all start poring over it for errors and places to add contingencies to make failures less catastrophic.

The next day she calls Vanyel and tells him they found only the memories of the four expected Gates and not any other magic performed since then.

He's talked with Fëanáro and Maitimo extensively in the meantime, and they are very suspicious. 

:Thank you. Do you know how Melkor got him to do the Gates, er, and why he stopped?: 

I haven't gotten into that much detail in my reads but based on general knowledge - uh, Melkor runs prisoners through hallucinatory simulations, often with memories added or removed, so he had a lot of tries to set up a convincing argument. I'm not sure how he stopped; any realization he made could have been erased. I can try to figure it out but we were hoping to let him be bored and not disturbed for the rest of the week and see if that helps him at all; is it important?

Vanyel hesitates for a bit, thinking. :I don't think it's urgent. So do what you think is best for him, I guess, or go with the other Leareth's judgement on it. Anyway:

Another pause. :We, um... I'm sure you'd understand that your story is very weird and also pretty, er, convenient? And we'd like to believe it but we have to be suspicious. It's hard to know what to do to verify it that's not a risk for us, aside from the other Arda being able to talk to Fëanáro here, I guess. Is that going to take a while?: 

He can make an earcuff like mine, but for that to happen I have to write down the whole spell, stare at it so he can copy it, and he has to translate it it into his own notation. This wouldn't take all week, except insofar as it trades off against error-checking the interplanar transit. He'll do it anyway but won't be done today. I can go loan my existing earcuff to the Vanyel here if you like though, that doesn't require any extraordinary outlay of time or effort.

:Just a minute, need to think about that: 

He does for a while. Comes back. :Sure: 

Next time you want to go think about something and get back to me can you give me a time to call you back? The earcuff has a usage limit. It's not small but I need it for a lot of things.

:Sorry, right, I can do that: 

:Thanks. I'll go bother this Van and get back to you.

She drops the call and knocks on local Vanyel's shields.

Local Vanyel answers right away. :Bella! I thought it’d be way longer before I heard from you! What’s going on?:

Spell mishap! We're okay but something really weird happened. Remember I mentioned Utumno? I landed in a place that looked just like it, panicked, and teleported back out with the nearest prisoner in tow, who turned out to be Leareth from an alternate future Velgarth operating in an alternate future Arda. Do you want to tell your alternate future self I'm okay for me? He's suspicious.

:Gods! How in the world did Leareth end up in future-Utumno? Also, um, does that mean the other Arda didn’t win the war with the evil god? Because that’s awful:

APPARENTLY in the future the Valar PAROLE him so mine are going to be warned and will hopefully pay attention. New edition of Utumno is called Angband.

:Eek. All right. I'll talk to the other me - er, do you have any advice for finding him? I've never used the earcuff to talk to people who I hadn't actually met: 

For me it worked to know that he's a Vanyel in that other universe I went to for a fraction of a second, it might be harder for you since you've never been but I can send you memories of the place maybe? And impressions of Other Van from talking to him.
