"How long do you suppose we might reasonably take?"

"If we take more than a candlemark then probably something has gone seriously wrong, but - also they are not at risk of starving or freezing in that period, so we could give it longer in case something very weird comes up. Three or four candlemarks, maybe?" 

So she tells all the gryphons that if no other orders from her materialize in the next four candlemarks they are to travel home at whatever pace of travel they would ordinarily prefer and are thereupon to consider themselves released, and then she gets names of all the other soldiers in the other detachment.

Leareth is busy scrying the other two groups. "The cavalry are moving this way in a hurry," he tells Promise in a low voice. "I assume one of the gryphons got a message out to them before you obtained their name. The human detachment is now three-quarters of a mile behind them. What order do you want to deal with them in." 

"I have most of the humans but not - that one that one and that one," she says, igniting fairylights over some of the individuals shown in the scry. "And most but by a lesser margin of the rest. How much should I assume being behind their allies would help deflect their attacks?"

"If they are attacking you but you have the names of the others and order them to block attacks? That will be very effective against non-magical attacks, it may not block all mage-attacks especially if they are skilled enough to cast without line-of-sight. I will be shielding, though, and can much more easily hold off a smaller number of attackers while you try to learn their names from the others." 

"Okay. Humans first and I will try drafting them for the remainder."

And Gate, and then they're a mile and a half away, landing right in front of some very surprised soldiers lined up to wait for their next Gate. They don't seem to have gotten the message about the gryphons. 

Leareth easily shields them before anyone moves. The mage-attacks are less coordinated this time and barely inconvenience the shield. 

They're probably really confused about not being able to harm her, that'll sure mess up an attempt at hitting her with a lightning bolt. "HOLD." And then of the nearest person, "Tell me the birth names of -" And she rattles off the fake names she has for three of the humans.

This person seems to know two of said names but gives her a blank wide-eyed look for the third one. 

She holds the two. "I'm going to brute-force the third," she tells Leareth, and she starts running through syllables from the rest of the human soldiers.

It's pretty obvious who the third soldier is, he's the one looking around at his frozen companions in horror and trying to scramble around them. He's conveniently not a mage, so even once he gets past them, his sword does approximately nothing to the shields around them. He looks so incredibly confused. 

Eventually the syllable 'Alk' clicks for him. 

"Hold."

Now a couple hundred human soldiers are standing around, mostly in their initial formations, not moving at all. 

"If you know the names of anyone in the nonhuman non-flying group raise your right hand straight up above your head."

The wind is picking up, whistling on the tundra, and the rows of humans furthest away from her are squinting and don't seem to have heard. Most of the rest raise their right hands. (Nearly everyone knows the names of the commanders of each nonhuman section.) 

"If you know names of that description other than -" She lists what she's got after the first couple have disgorged their information. "- then keep your hand up; otherwise lower it."

About a quarter of the humans know at least some names of the nonhuman rank-and-file, and keep their hands raised. 

Leareth is so impressed! Plausibly he should be scared, but there's too much amazement and awe to leave room for that. He keeps shielding them even though it's hopefully unnecessary at this point. 

Promise collects names till she thinks she has all she's going to get, and then starts brute-forcing the rest of the bunch with names from their conspecifics, as long as she has time.

Leareth warns her when the nonhumans-and-cavalry section is getting near to the grounded gryphons. 

"I'm figuring out names, some syllables seem pretty common - scrying them more might help -"

Leareth scries them and lets Promise watch. "I am not sure if they can actually cause trouble when they reach the gryphons, they presumably cannot reverse your orders -"

"We didn't exactly experiment with interactions with your own compulsions." Names go snap.

"True. Everything has happened in such a hurry. Rude of Vkandis, really." 

The cavalry catch up to the gryphons at the point when Promise has brute-forced half a dozen missing names but is still missing around a dozen of them, mostly the kyree wolf-creatures and dyheli deer-creatures, who seem to have a very wide space of name-syllables with fewer repeats. They appear to spend about thirty seconds attempting to talk to the gryphons. 

Then a Gate goes up right next to the gryphon leader, who is immediately lifted - not an easy task, for nonhumans that mostly lack hands, and it looks unpleasant for the gryphon - and shoved through. It looks like more of the cavalry are going after the other gryphons to drag them over too. 

"...Possibly we should move now," Leareth says.
