They are not too bothered by a flying shuttle excursion.  Fëanáro thinks that it's not necessarily undesirable if the parley imposes only net strategic advantages compared to staying home but the Enemy'll probably negotiate wording anyway so may as well start with Melian's version.

There are eighteen more hours to parley time. 

Cam drops off the diplomats and goes to find Maitimo.

Ossiriand is the same as he left it; Maitimo hasn't even had enough time to design a city expansion yet. 

"Hi. My idea works. Hammered out a proposed oath wording, want to look it over, new pair of eyes?"

"Yes, please."

Here it is! "Gonna rain it with little recorders in parachutes over Angband, with this frame letter -" And there's the frame letter with instructions on recording, negotiating the wording, etc.

"I expect that if you were fully informed you would agree to the parley", he says immediately. "Otherwise looks good."

Cam adds that in, CC's Fëanáro.

"I would be a lot happier if I knew why he asked for me. But I think this is worth it."

"Yeah, that's bothering me too. If anything goes pear shaped I can melt your chip, don't have to wait for results on the test subject. Assuming I notice it's going pear shaped, but..." Sigh. "Rain of parachutes time?"

"...they could try to use illusions such that you didn't notice it was going pear-shaped, maybe. Add a clause about that."

Another round of editing and encrypted texting!

And one last one, to add to 'I will not lie' 'I will not attempt to create the impression I've given an oath when not doing so'.

Edit edit. "...now, or should we stand around for fifteen minutes waiting to think of another thing?"

"Let's stand around," Maitimo says, though in fact what he does is pace and sing. 

If only Cam could read local sheet music he'd violin along. He sits and listens with half an ear and thinks. "- wasn't Melkor personally who wrote the invitation, do we need to disambiguate between them for this to hold?"

"We should ask for oaths from the both of them. I am sort of expecting Moringotho won't come in person, or if he does will send only a tiny fraction of his attention. No one wants to sit through the annoying static-electricity-and-air-pressure effect while trying to think."

"It is irritating," Cam agrees, fiddling with the text to account for needing the oath from both. "They can do colocation?"

"Not particularly well, but yes. They have about a thousand times our active attention and working memory but have an absurdly hard time doing things like 'get Elf-equivalent sensory input', it was once explained to me that they have to design biological bodies for themselves on the level of doing all the protein folding manually to have one."

"Wow."

"And he's fighting this war with machine guns. Though our Angband-trawling suggests he's about to escalate to tanks." He shakes his head. "Yes, let's add to the cover letter that we want this oath from the one who wrote the parley letter, Moringotho himself, and anyone attending the parley on the Enemy's behalf."

"Machine guns and a prion disease. The prion disease is concerning. I wonder if it's actually functional that it just seemed like 'poison' to the victims." Edit edit.

"You mean he'll do sophisticated things and try to make them look consistent with the apparent tech level. Though we're doing the same thing."

"Yeah, exactly."

Fifteen more minutes of thought produce no new proposed revisions.
