Leareth isn't afraid. (It's really so helpful, that part, though somehow he hadn't imagined it would be.)
The alertness of adrenaline and urgency is still there, as he sits and thinks and occasionally has brief Mindspeech exchanges with his staff on site. There's so much to do. He makes a mental note that he needs to have [name redacted] contact her father [name redacted] in Golarion, check in on where they're at with the resurrection contingency-setup for Carissa - and himself, but that's an afterthought - oh and another note to himself, he really does need to sit down with Iomedae's people and talk about what to do with his immortality setup. Golarion resurrection is straightforwardly a better backup plan, anyway, it's faster and much less lossy, and - after some extensive thought - he thinks it's very unlikely anything will happen that prevents that from working and doesn't also block his own method - presumably the Soul Bind magic would also prevent his usual way...
(He's not afraid. He can think about it calmly, levelly, which feels miraculous.)
...He's worried about Vanyel. (A lack of fear doesn't mean that he can't feel any kind of distress, about bad future outcomes for people he cares about - if anything, it makes it easier to notice and interact with.) The Heralds are angry - of course they are - but he is absolutely not sending Vanyel back to that hornets' nest. ...And he still hasn't actually had the conversation with Vanyel, yet, about whether his suicide attempt was impulsive or overall-endorsed. It seemed like a better idea to wait, let him rest - he was in such bad shape even before all of that happened -
- he Mindspeaks Nayoki, asks her to scry and check on Yfandes again - no change, apparently, except that only one of the paladins is with her now - he asks Nayoki to check on Haven, too, see if the Chelish diplomats have actually left yet, so he can close that open loop...
...probably none of the other Heralds is going to read the King's mind and learn about [name redacted]? He's not sure about King Randale's Companion. The entire Companion situation is such a difficult mess - and, again, he feels a pulse of gratitude for Vanyel's determination to warn him, even when he must have been in so much pain.
- troop numbers, he needs to get them in place to transport via the minimum number of Gates - also he really needs to test the interplanar Gate spell properly, soon, but...on reflection, hmm, it probably makes more sense to do it from the Golarion side? More familiarity with the search-destination, and it'll mean he can set up shields against detection on that side - that's one of the ways that Asmodeus could be warned of what's happening -
(In the back of Leareth's mind is an intermittent litany of not alone never ever again...)
