There's no free chairs. Keltham will sit down on the ground, breathe to recover, and try to figure out everything he just did wrong. Was he supposed to use the Owl's Wisdom? Could he have seen this all coming if he'd used the Owl's Wisdom on himself at the right time? Why put Keltham right outside the Forbiddance when this all happened? How is anything being predicted that finely, even by gods, thermal noise doesn't let you pull that kind of shit, isn't prophecy supposed to be broken around here? Possible answer, that was an event triggered whenever Keltham went outside the Forbiddance but then - then -
Keltham really doesn't get it.
