That's what Companions are for!
Seldan will stomp very hard on the temptation to start freaking out again because his Herald came close enough to dying to talk to the Shadow-Lover aaaaah! It's fine, Blai is fine, it's just that this was incredibly stressful and he's unendorsedly mad that Leareth didn't think to send them someone who could cast unscaffolded Gates underwater with enough speed and precision to have just squirted Blai out through one of those in the first ten seconds. That's a sufficiently absurd thing to be able to do that possibly only Leareth can do it and there are 5847843 reasons it would be stupid for Leareth to personally show up in Haven to guard Blai, where "everything that just happened" is an excellent demonstration of those reasons, AND YET.
(These thoughts are in the background but not entirely hidden behind shields. Seldan can't actually spend the next five years concealing all the ways that Blai is important to him and threats to Blai are upsetting just because Blai is not totally comfortable with being loved by someone.)
...Huh, the Shadow-Lover is not very good at communicating but is...clearly making an effort? And his sense is that that was actually a more productive conversation than Vanyel's usual experience; he wonders if the Shadow-Lover was benefiting from the fact that Blai's world has more state-of-the-art for communication with gods.
Message for Leareth, got it. Vanyel already suspected that the Shadow-Lover had been steering for something other than Leareth's permanent death, and the - adversarialness - of that plot is probably explained by the fact that apparently the Shadow-Lover god can't talk to Leareth at all because Their communication interface can only reach dying people and Leareth doesn't die hard enough to count.
The god is in favor of them reaching Golarion - that's very good to know, Vanyel had hoped They would be but wasn't sure -
The god has Yfandes and isn't inclined to interfere with bringing her back, that's good, he's very glad they know that. The kyree god is Kernos - does Seldan know any facts about Kernos - it's not a well-organized church like Vkandis has but there are martial orders, Kernos is popular in the northern half of Valdemar, he thinks Kernos has ever been known to give people miraculous fighting ability to defend people they care about though he doesn't get the sense it was ever very targeted...
Souls aren't actively unable to reach Golarion afterlives from here, it's just that it's not the standard destination if a Velgarth god has remit, that's interesting...
Seldan can maybe get messages to the Shadow-Lover! That's really interesting! Because he's...closer to Foresight...ohhhh he thinks he sees how, now...wouldn't have occurred to him to try it otherwise, but mostly because he wouldn't have assumed the god was paying active enough attention to act on anything he tried to communicate...
Awwwwww Blai got a hug. And liked it! Awwwwwww. That almost makes this feel worth it.
Seldan definitely getting the sense that the Shadow-Lover god allowed the Star-Eyed to intervene for this to happen - maybe They were counter-intervening just a little at the end, it was a coincidence in their favor that Vanyel was close enough to be there within two minutes, but They let the bridge collapse happen because the Star-Eyed was paying for it but it was incidentally quite convenient for the Shadow-Lover's god if Blai could almost die. Maybe that wasn't actually unfriendly, maybe this is literally the closest to friendly that the god can manage, but also SELDAN IS KIND OF MAD. NO ONE IS ALLOWED TO DROWN HIS HERALD.
