There's an amphitheater, a place where a hundred of the stone walkways twine around to create space for a hundred thousand people to sit in close proximity, and someone is giving a lecture or a demonstration at the base of it, the seats closest to him filled with eager, tiny, bearded Dwarf-children.
And they spiral down, and down, and down, past waterfalls and egg-sized gemstones left half in the rock and halls of crystal. Everything grows gradually more ornate and more perfectly maintained and the clang of hammers fades behind them. "People say," her guide says, "that we only have a council instead of a single King because there were nine winners of the competition to design the throne so we couldn't just select one person to sit it." And they push open the doors to reveal, indeed, nine thrones so elaborate it would be hard to choose between them, and nine squat bearded people sitting them.
"Um, there's an orc you met in the mountains who you learned about our oaths from, and we watched you talk with her. She's back now so we can look at the things she remembers. And she also remembers when you were in the Elf camp and talked with more orcs there, and killed the disobedient ones, and tricked the others. And then the last orcs he sent out to say hello to you out here, when you were blue and scary. He thinks that's all the orcs you've talked to. If there are others we didn't see that."
"How exactly is he showing you these things without access to the orcs in question?"
"He sends someone out to be a hundred miles away and watch through our minds with osanwë. He can't go personally because he can't maintain a physical form right now. But they can read everything we're thinking so they know what we say and they know when we die, and they can take the whole thing back to him to learn from."
"I'm not a Man, I have seen babies before." Heal. "Are there special baby orc care and feeding guidelines to worry about?"
She flexes her hand like it's unfamiliar. "Huh. Thank you. They don't eat solid things until they're this big, usually," - she gestures - "they drink from our breasts, but I suppose it'd be better to give them solid food than let them starve. Or if you have animals, the milk animals produce for their babies works. Not as well, but it works."
Loki thinks.
She stands up.
"Will the adults hand the babies over voluntarily? I may or may not have an idea for not killing you, but just in case I want the adults separate."
And she goes out. And she heals all of the orcs - paying close attention to whether the babies react to this treatment or not. And she has them hand over the babies to any Men who want to practice holding babies and if that's not enough to go around she enlists Elves.
And then she inquires of the orcs under lie detection if their current orders allow them to change tactics, and if their current communication situation allows them to receive order updates.
Their orders do allow them to change tactics, except their specific current orders include 'don't fight back or hurt anyone even if you think it's the best way to achieve your goals' so they can't change that tactic. They can be communicated new orders via osanwë.
Need an Elf's eyes up in the sky with me.
Can you see a hundred miles or is this going to take a while?
Right, but none of the time will have to be search-transit time. Here's the deal. I'm sure whoever Thauron's got out there mindreading the orcs is invisible. Only makes sense. I have an idea that might work to find them. Then I can go increment my Balrog tally and as long as somebody's always up in flight to notice and give a warning if something else enters the vicinity we can leave the orcs alive in some hacked-together social disaster. My illusions have no range limit. They react to real light; and they react to each other; my guess is they will completely ignore whether or not someone is differently invisible. I'm going to flood the entire radius and then some with color and you're going to tell me if you spot a shadow.
I'm considering it. But then he can just keep sending them at no cost and they loiter around, maybe surround us. I don't think he can afford to lose Balrogs the way he can afford to lose orcs, either.
