"Overnight" was, like, two and a half candlemarks (can Blai also nap later with the Nap Stack spell?) but Seldan has gathered some reports!
They're in contact with Waymeet, and Haven indirectly; Leareth sent in someone un-Gifted with one of the messenger-bird mage-constructs to ride in from five miles out rather than scare people with a Gate directly there, and then the Heralds in Waymeet eventually agreed to Leareth bringing in a couple of mages who can rotate comms-spell duty.
Jisa read Brightstar's mind and determined that, while he did have time to go and sabotage Leareth's immortality backup hard enough that he would have died permanently if they'd managed to kill him on the battlefield, he didn't tell anyone else how to find it and even if Iftel wanted to send another attack, without Brightstar they have no way to locate Leareth. It's not impossible Vkandis has enough forces still in Iftel to send a bunch of them north at semi-random anyway, but Leareth has dozens of bases across hundreds of miles, not to mentions underground records rooms scattered around the rest of the continent, he should be able to stay ahead of them for the week or so that Jisa think it would take him to repair the damage.
(As an aside, Jisa guessed that the girl in Blai's vision was the sister Brightstar apparently has, whose name is Featherfire and who lives in Highjorune, formerly a small kingdom that existed even in Seldan's time, apparently annexed by Valdemar in the last decade. This has got to be a really unpredecented rate of annexations, Valdemar also expanded north to Waymeet and west all the way to Lake Evendim in the last decade, doubling their effective population in the process.)
Nayoki wants to transport them to Leareth in two hops just in case the Star-Eyed Goddess can still work through Brightstar somehow, even though the earlier Minor Prophecy implies She probably can't. Arrangements for that are ready when Blai is.
After that, they can get a Gate back south from Leareth's people, probably directly to Waymeet, and get another Gate from there to Haven. Poor weather-mages, lots of work to do. (Seldan isn't actually feeling apologetic.)
There are apparently also some surviving injured and set-commanded gryphons - ones that fell out of the sky outside of Blai's channel radius before - as well as some injured kyree who were dug out of the rubble, now transported to Waymeet. (Plus some miscellaneous injuries related to, of all things, several bar fights that apparently broke out amongst all the troops who were suddenly left at loose ends in Waymeet once the Heralds sent the order to stand down the war preparations.) They can probably all be fit into a channel radius, if Blai would like Seldan to send word ahead for them to arrange that.
Vanyel is probably coming back to Haven with them but Jisa will stay up north with Brightstar. She thinks that under no conditions should they bring Brightstar back within the Web.
