The first thing the demon says is, "Holy fuck, I can talk!"

"Hello!" he says brightly. "You have been summoned to a different dimension, you'll notice the circle's much more complicated than usual. It should simplify paying you; I am guessing you have not heard any of our music, and sometimes I get lucky on the relative tech level. Do you have faster-than-light travel?"

"...We do not have that thing!"

He beams. "I want an equipped fleet of three hundred lightleapers. In exchange you get the blueprints for lightleapers. Deal?"

"...Probably yes but this is the first time I have been ungagged ever and I need to tell you something important. Summoners become daeva when they die. I'm an ex-summoner. So's my sister. She's an angel. Can I talk you up to blueprints and summoning her for a while so we can see each other because if I have to pick it would be socially irresponsible of me to pick my sister."

"She gets the same binding, and we're leaving in a week so I can't give you longer than that, but deal.

Summoners become daeva if they die? I do not think that's the case here."

"Then I guess it's not salient to you personally, I suppose. Most daeva aren't ex-summoners, we're a minority," she adds. "Anyway for future reference I am the easiest-to-pay demon ever since I have a repeatable intangible, although of course I retain the right to refuse deals on ethical grounds. If you needed a demon again. Where d'you want the ships?"

"There's space right outside." He gestures. "Maitimo, by the way."

If she has ethical concerns she might hesitate when she notices that this is definitely a fleet of two hundred warships with active weapons systems. Hopefully she does not notice that immediately; maybe warships look different where she's from. Or her ethical reservations are more on the scale of 'no feeding planets into black holes', which he's not currently planning to try unless things look really bad in Endore.

He pulls up the blueprints on a demon-safe computer and hands it to her. 

Some things just scream 'weapon.'

"Are those...battleships of some kind?"

"Yes. The hwesta-class are carriers and those will each have a couple hundred smaller ships for atmospheric engagement; everything else is a warship. I can also get you the blueprints for a civilian lightleaper to take home when you're done, if you'd like."

"I think under the circumstances I would appreciate some context for why the battleships."

"There is a war. We didn't start it, but we are planning to end it. The other side recently fed this system's suns into a black hole, if that helps you evaluate who the good guys are."

"Do my bindings prevent me from playing Infosec Hazard to the point of verifying this?"

"You can't break the law, but I bet you can summon scale models of everyone who died in the fighting on Endore yesterday and you can definitely summon our newspapers and so forth. I can also swear to it, but if people in your universe die and become daeva then I'm guessing you also don't have oaths."

"People make promises but I'm guessing you mean something else from context. Not that I can guess how that interacts with the other thing."

Newspapers! What do the newspapers say.

The newspapers say that one month ago, Melkor fed the Suns into a black hole, and the Valar are working on replacement options for the star system, please have patience and don't do anything drastic.

She's pretty sure this counts as something drastic.

"Who are the Valar, and is the fact that it looks like they don't want you to do what you're doing going to interfere with my don't-break-the-law binding?"

"Building the ships isn't against the law. Emigration is also not technically against the law, just heavily frowned upon and will get our citizenships revoked. Going to war in Endore is against the law but I didn't summon you to participate in that. 

The Valar are daeva. Unbound daeva whose summoners are unknown and I'm guessing in artificial suspension on a planet really far away where they will never be found. They are the rulers of this galaxy."

"Well, then. If my sister and I are going to be here a week I think I'd like to know more about the situation as it stands in that time, but that, uh, yeah."

"Not the case back home?"

"Even aside from the fact that we don't have FTL and therefor it'd be pretty damn hard to rule a galaxy even for a daeva, no. ...We also don't have reliable suspended animation, which may contribute."

"Have you heard enough to decide whether you'll make me my ships? I have no desire to be rude but I am confident of finding someone who doesn't want to check and there are quite a lot of people dying as we speak."

"Yes." Ships!

Lovely. 

He did this on Araman because it was safer if they made a mistake - and less likely to catch a Vala's attention - but the rest of the host is still back in Tirion. He draws up her sister's circle while she builds the fleet. 

"Hello, summoner, what may I--" the angel begins, before spotting her sister and cutting off her greeting and professional smile with a grin of genuine delight. "Edie!"
