"That sounds amazing. Wish I could see it." River sounds a little wistful. 

"It's not a great idea for mortals to go tromping around in Fairyland."

"That's certainly the impression I got." Wingsister shifts her weight, her eyes going unfocused as she presumably Mindspeaks someone else. She's quiet the rest of the time that Promise spends staring at patients. 

Promise heals everybody they put in front of her. De-aging the same people doesn't require additional staring, if they want it.

Only a handful of them are old enough to want it especially - several of the patients she's just healed are children. 

"Er, we've got another destination after this one," Wingsister says. "If you're still up for that." 

Children are weird. (She doesn't tell them this.) "Okay? Same thing or another meeting or what?"

"Er, for healing mainly, but involving people who kind of want to meet you diplomatically. I don't think there'll be much in the way of specific questions, at this point, just - our Council will feel more comfortable with the whole bizarre situation if they've seen your face." 

"Uh, okay."

Whenever she's done healing all the patients here, Wingsister leads her back across the gardens to the original ancient stone building. 

A number of mostly-quite-elderly men are sitting around a big table. All of their eyes immediately turn to her. 

And another man is there, young but not exactly healthy-looking. He stands. "Welcome, Promise. I'm the King. It's an honour to have you visiting us in Valdemar." 

"Nice to meet you."

The King takes a deep breath. Glances over at his Council. 

"- I have an illness that seems incurable to our Healing," he says quietly. "If you're able to fix that, it would help us a great deal, and - given everything, I've decided that I trust you to try." 

There are meaningful looks exchanged. Some of the Council members seem vaguely unhappy, shuffling in their chairs, but no one says anything. 

"I'll see what I can do. I only have the one spell, but it's supposed to work on anything."

Serious nod. 

The Council members eventually get up the courage to ask her some polite questions about Fairyland, only somewhat repetitive with the previous day. They want to know about plants and whether there's farming - do they have forestry? Any mining for precious stones? 

"There's gardening, and fairies will cut trees to build things, and dig up pretty rocks, but we don't live in groups as big as you do so it's smaller scale."

They listen politely, nodding, and have some followup questions, none of which are all that interesting but they pass the time while Promise is staring at them to de-age them and the King to heal him. 

She does the King first, since that's simple, then asks all the old people how young they wish to be.

Oooh, wow, do they get to decide??? 

They get a mirror in to watch so they can tell her when. Different people choose different final ages; some prefer to stay looking in their mid-forties, with dignified silver at their temples and all, whereas others prefer thirties or even twenties. 

Her aim isn't perfect (one person will have to wait a few years to restore the desired silver) but yes, she can try to aim for those decades.

They totally understand that beggars can't be choosers and they really, really can't complain about the FOUNTAIN OF YOUTH being a bit imprecise. They're so delighted with her, beaming and wanting to shake her hand. 

:If you would rather not shake anyone's hand, I'll politely deflect them: Wingsister tells her in Mindspeech, since she doesn't know if fairies have that practice at all and it might be uncomfortable for them.
