"If you were a bird, you'd go to Melkor and he could read your mind and he'd want you to be a spy. Unless I could get every single one of the orcs and make sure there weren't more orcs, it's not better for him to have spies than warriors."
"...Depends on what you mean by 'orc'. I don't want there to be people who are in pain all the time. I don't want there to be people who have to hate and fight Elves. There might be other things that are true of the orcs that there are now, that I don't want. But if there can be orcs who don't have those traits then it would be good for those orcs to be, and be happy."
She lets it up, the better to pace. "I don't know what would happen either. I think I need to talk to someone who knows more about oaths than I do. Unfortunately, short of going and seeing if Melkor feels like talking without having to read my mind or kill me or something like that, all of those people are Elves; and I definitely can't leave you here unattended."
"Yep. And you know a lot of things Melkor mustn't know, now. So I suppose I could turn you and your friends all into birds temporarily and tie you up and carry you to the Elves, which I imagine you'd find very unpleasant but it'd mean I could keep an eye on you while I asked them about oaths."
"Yes you do. You know that I can turn people into birds, and stop orcs from hurting, and be invisible; and that there are other worlds. Things like that."
"Because then you have more information to use to think of ideas. There are things you know that I don't, and if something I know plus something you know is a good idea, and if you don't know exactly what to tell me or you can't tell me, then I can put those pieces of information together by telling you. I couldn't risk it if I didn't know that I can kill you if I have to, but I'd still rather not."
"You will be a bird and tied up to boot," she says, "so you can try all you like; and you will be a bird and I will explain before anyone realizes that you are not, and I will object if an Elf tries to kill you before thinking it over."
"Anything you want to say before you can't talk for a while," she says. "...My name is Loki. Do you have a name?"
"No. We're named when we're born. Some people have the same name, but there are still enough names that usually people can tell who you mean. I did have to earn being considered an adult, though, I had to go kill a creature that was bothering a town without help or magic."
She has string - she has, in fact, fancy high-tech string that in Asgardian fashion looks like twine. She knots it around wings and loops it around feet.
She turns the other four orcs into birds too, and ties them up, all in a line. Then she heals them, in case they wake up on the hike; she can't carry five swifts while she is one and she's going to have to walk. She scoops them up; she could dangle them but this is more comfortable.
The swifts can't speak. But Loki can. She explains, on the way, the contents of the conversation she had with the one orc, and where they're going, and why they don't hurt anymore, and that they will not have to die as birds even if it does turn out they have to die; and she will listen to their ideas, if they come up with any between here and their next chance to talk; and she will not let Elves kill them while they're helpless.
Hike hike hike hike hike she only just recently learned to turn into a bird and walking shouldn't have become this tedious this quickly.
