Kilchas will try to reach the nearest Herald on Mindspeech-relay duty, and end up having to ask them to bounce him to someone else because the youngster is sixteen, newly in Whites, and hasn't been to Waymeet either.
Rohan has a bad feeling about this, and is tense and fidgety in the back of Kilchas' mind. Kilchas can't even disagree that it feels doomy. He's in a terrible mood about it, actually.
But it sounds like Iomedae is at least much less at risk than anyone else would be, meeting Leareth to negotiate. She's hard to kill. Who knows, she might even be able to beat the man in a fight. And Leareth can try to kidnap her if he wants, but he's going to have a hard time holding her, if she's immune to his bloody compulsions.
And...they do need to negotiate with Leareth somehow, if they don't want to end up in a war that they very plausibly can't win. It would be so tragically stupid to end up in a war that both sides would have preferred not to have. And Leareth's letter isn't proof of anything, it's still just words, but - convincing words, he makes some compelling points.
Kilchas can almost hear the voice of Tran griping that they should be discussing this over a full Senior Circle meeting. But that would mean even more Gates, that everyone is too tired for, and...well, Iomedae isn't Randi's subject, and doesn't take his orders.
...He cannot in fact reach anyone awake and in his range who's been to Waymeet, which is stupid, but he can reach a Farseer, who can relay Farsight imagery clear enough that, with more concentration than Kilchas has ever needed for a Gate before, he can use to raise a threshold on the sturdy oak doorway of the town hall. It's just barely big enough for Rohan to fit through.
He even makes it across without embarrassingly collapsing on his bottom, though he's going to sit down on the steps of the town hall as fast as possible.
