And there is a shower of dramatic magic aimed at Earth teenagers and vaguely annoying to millenia-old Noldorin warlords and he stops piloting the body directly, is anchored in the gem, and then sudden conscious knowledge of his magic and how he can use it, and a dark red costume - loosely fitted, at least, and he adjusts it to leave no skin showing and the skirt to be floor-length and now it's a very nice high-collared Elven robe, there - and he can have his hand back if he pleases so he sets to work on regrowing his hand. 

Does that mean it worked.

Yeah, but we'd have to go actually check for details.

Body: restored to health. Pain: significantly lessened in general. If he thought any of this were real he'd be utterly floored with joy right now. 

Anything you need to know to do that?

Nothing in particular. How to tell if they're really dead, I guess.

Orcs swear him binding oaths. If they're no longer bound to serve him, he's dead.

Okay, where do we find an orc and how do we learn if they're still bound to serve him?

Angband has millions of them. We're besieging it; if you don't want to jump straight into Angband, which might be a bad idea, Fingon or I can tell the besiegers to expect you. If they're not bound anymore I expect the place will be chaos; orcs are also pretty straightforward and will tell you if you ask, especially if they decide to be scared of you. They're very compliant around people they're frightened of.

...lovely. Okay, having besiegers expect us sounds like a good idea.

Done.

And here is your copy of the happiness song - She hands one over out of her shield, tells him how to play it back.

Thank you very much.

You're welcome. Where or near whom in the siege is a good place to land?

They exchange glances, then pull out a map and show the two of them Angband, good vantage points on Angband, the encampments they've dug in besieging it, and so forth.

And when a good spot has been picked Bella glances Lúthien's way.

Pop.

He didn't seem particularly happy, for caring so much about it.

May have been running entirely off negative emotion. His gem wasn't precipitously dimming so he must have it under control, though. Or he's just really unexpressive.

Where's somebody who can put them in touch with orcs?

The Elves can break down the door of Angband, if it's expected that the war's over and the orcs might want to talk. There aren't any convenient orc captives or anything.

...well, she's going off secondhand reports on how likely the orcs are to want to talk but if the plan is breaking in she can just do that like so, no need to batter the door all medieval-like.

Then best of luck. The Elves look nervous but they got instructions from their leadership, they're not going to be stupid.

Bella magics the door open in a blaze of probably intimidating purple light.

There are orcs. They shrink anxiously back from the door and stare at her in wide-eyed terror.

Gonna need osanwë help, Bella says. And aiming to be relayed to the orcs, I came to check if the Enemy was dead. Supposedly you would know.

She relays. 

Did you do it? asks one of the bolder orcs. What are you, are you an Elf?

I helped. I'm a puella magi.
