"It depends on how that works, I guess? If it is dependent on the mental properties then no, if it's inherently magical then no, otherwise should be."

No one really want to suggest testing that. It's so pretty!

At least it serves that purpose!

And if that'll be all, off Cam goes.

If he's going to Endore, he'll meet the rest of the fleet there. 

Hello rest of the fleet! Of interest: basement dweller Silmarils only. How're you doing over here.

"Huh," Feanáro says, "I suppose I could have predicted that. They probably don't have the useful properties in that case. Mindless Silmarils probably don't count for Oath-related purposes but let's still not go handing them out, I am not sure if they'd still be weaponizable but they might be. Can we get ships that can land up safely on Endore? And you were originally going to spend this time talking to people to decide whether to do weapons; have you had the chance to do that?"

"Oath-related purposes?"

"The Enemy has the Silmarils, we've sworn to be undeterrable in various ways from getting them back. Before you arrived they were the only hope of achieving an Eldarin civilization outside Valinor. Anyway, pseudo-Silmarils in the hands of my subjects are certainly fine."

"Okay, I wish you'd told me that, I could have decided to experiment with making them in some other way and could have gotten different results and then where would we be."

"With a real Silmaril in the hands of my subjects which would still be fine. They're not going to start serving the Enemy. You'd be better able to aid us in the war if I had mentioned it and I should have."

"Having more of the things you're sworn undeterrable in retrieving around sounds like a bad idea. Anyway I've gotten lots of reading and talking to people in and you seem okay but I don't know anything about opposition, I'd like to do drones before landers."

"I agree, because we also don't know what we're facing. Go ahead."

So Cam makes a nice fleet of drones - he doesn't surround the whole planet with them, that would be giving a bit much away - and they descend upon Endorë.

It's pleasant. Temperate, visible cities, visible areas where there's been recent fighting. In the north there's a sprawling heavily industrialized area that's easily the most populated part of the planet. 

Drones spread out and get lots of video. Cam will share with the Elves.

There's fighting going on on the coast of one continent. It looks like both sides are dug in and have been for a while. 

There's an area several hundred miles across that his drones all vaguely meander away from due to flight course tracking issues. 

"...that's weird. Second opinion on whether I should manifest one inside that area?"

"Assuming they're doing something to make them go away, I'm gonna guess they won't be friendly to one that appears there. But I guess no one's likely to get hurt."

"Yeah, the question is whether you might want these people to like you later or something."

The King snorts. Maitimo winces. "I am thinking we very much want everyone to like us, we might end up trying to talk them into evacuating."

"I could drop them a letter if you think they'll be able to read Quenya?"

"Languages diverged over three thousand of Endore's years ago," the King says, "I am nearly certain they won't. Being indestructible I suppose you can always try to do the 'we come in peace' approach with minimal consequences. Can you summon the kingdom's documents from its approximate location and nothing else? I could pick up their language and drop them a letter in that."

"I can... probably do that if it is in fact a coherent political unit in there. It'll be their complete works or from like a time period, I can't be selective on this little information."

"That's fine, we're just trying to learn the language."

"And they haven't got the infosec handbook," sighs Cam, but he goes for it.
