"You have a skip-a-night-of-sleep song and a speed-up-perception song because I sang them for you. As I recall when we had need of your magic you asked quite a price for it. Can you carry an illusion of the contents of the room with you, so you can observe whether it's been commandeered?"

"No, it's working off mental images and persisting from there, I can't turn it into a video camera. I don't doubt that you're a particularly good source of magic songs and I really appreciate it and I wish I could just go around dispensing gifts to everyone indiscriminately but I am dealing with an awkward détente here. If my sister plummets out of the sky, finds out I'm a frost giant, and despises me for it, you may feel free to carefully equalize your distribution of things between the two of us, I won't be offended."

"Understood." He stands. "Should I find an appropriate room for the perception-heightening and sleep-skipping?"

"Should probably be different rooms, people might want to hang out in the one and just visit the other."

He nods. "I'll send someone when we've settled on them."

"Thank you for the songs."

"I enjoy discussing magic and have not had the occasion to do so in a while."

"Anytime."

And he leaves.

And she plays with accelerating the perception-speedup spell. How fast will it go?

There's a point at which it stops working, but nothing obvious about that point - it's not the place where the notes stop being distinct.

Quite a bit of subjective time later, someone knocks on the door to tell her that buildings have been selected for this purpose and she can set them up at her convenience.

She disassembles and baffles the spell, puts away her work, and goes to make the installations.

The person supervising the installation explains that Macalaurë asked them to spend the next while in subjective time and see if this had any negative effects - "which we'll tell you about as soon as we know about them."

"Thanks!"

And then no one has any more requests of Loki.

Does anybody have more songs for her? Or should she use her sleepless night to go tell a presumably also not sleeping Findekáno about the hack?

"I don't have anything else I'm comfortable sharing," Macalaurë says bluntly, "which isn't distrust in you but a reluctance to trust everyone you trust and everyone they trust. Healing we can get you, if you'd like."

"Yes please."

So he finds someone who does healing, and she plays a song - "most people do this with instruments, Lord Canafinwë was unusually determined to have his hands free -" and observes that range can be amplified and it should affect everyone in the range on either side - "It's not really meant for use on a battlefield" - and that Elven healing can't for example regrow limbs, though it can do a fair bit for wounds to the mind and soul.

"My primary use case is keeping somebody alive until I can get to touch range, so not being able to regrow limbs isn't a prohibitive drawback," Loki says.

"That it should do."

"Thank you very much."

A nod. "We've been trying to write something that would help orcs with the constant pain, but none of them could describe it helpfully. That may be something better suited to artifacts."
