I'm thinking if there are conditions that all of them need to work in - like, if they need to be near you, or looking at you - then I should swear not to give out my magic, or kill anyone, until I'm not in those conditions?

There's no such theme in powers, I'm afraid. Some masters need to meet you once, some need constant contact, some need to only see you even through a camera.

Ugh.

I will call Copy once more and you can try to test your oath versus their power?

Sure.

So a few minutes later the pierrot arrives again.

"I swear for the next hour or until I say 'escape clause' I will not make any movements I didn't intend in advance."

The pierrot inclines their head, and looks into Fëanáro's eyes, and raises one hand again.

He can't move! At all! It's not pleasant but his hand does not raise!

Copy nods and breaks the connection again.

"Escape clause - thanks -"

You are quite welcome.

Off they go again.

So you can resist powers that make you act in ways you'd be sworn not to, that's—useful to know, sends Legend.

Yeah. I should probably swear not to feed the Earth into a black hole or teleport it into the sun or things like that but oaths can be really bad, we'd want to be careful with phrasing...

And those are unlikely to be problems in any case, most villains don't want to actually destroy the Earth.

Yeah, and subtler stuff is - more complicated - do you want to help me think of a phrasing -

Library of Alexandria might actually be a better bet for who could help you.

Okay. How do I send her a message?

Legend floats back into the room. I will email her, she will surely be able to come here soon to help you with that.

Thanks. Shiver. I miss my peal.

He hugs Fëanáro.

Oh good that's good. Hugs.

He touches a comm device. "Please email Library of Alexandria and tell her we need help coming up with safe oaths for master and stranger resistance. She will understand."

It's so good when there are other people who can be in charge of stuff.

We still had a few people lined up. I don't expect them to be any more revealing than these first two, there was a reason why we picked them, but.

I can do more if you want.
