And Altarrin, with his own context on the Emperor’s court, can look at the what and the why and fill in some of the how. The Empire is designed for paranoia against gods, and - the gods of Velgarth can use that, as they did before to make sure Altarrin wouldn’t learn enough of Iomedae to turn back before he killed her. Kastil isn’t the only one who would look at Altarrin’s note and see it as proof that Aroden has already suborned him, but he wouldn’t be surprised if Kastil is involved, he’s - someone the Emperor leans on in times of stress and uncertainty, especially if Altarrin isn’t available. Bastran is going to be terrified, overwhelmed, looking for answers from any other direction, and Altarrin hasn’t been there and so his advice has been coming from…people who aren’t Altarrin…
He - doesn’t know how badly it will go - he mostly can’t think about that at all, actually, trying makes the screaming in his head worse and the walls of the tunnel even tighter and he can’tcant’can’t - he’s not thinking clearly but he knows that, damn it, he does not need the stupid headband self-awareness to keep pointing it out, that doesn’t help achieve his goals, it doesn't serve the Empire -
The screaming quiets, slightly, and there's a little more space to, not finish that thought, but find a way around it.
…Iomedae would say it doesn’t matter. She doesn’t care about the difference between ‘Altarrin has a respectful conversation with the Emperor, who eventually makes a tortured decision to ignore the Knights of Ozem’s overtures’ and ‘Altarrin is thrown in a cell for questioning.’ From her vantage point, the relevant difference - the crossroads that will let the Knights decide whether the Empire can ever be an ally - is what happens to Oris and what happens in her own war.
If the Empire can’t be an ally then, from Iomedae’s perspective, it’s a threat. Regardless of whether the Empire commits not to invade her world, or whether she would even trust that commitment from them, but simply because the Empire is an enormous pile of resources and soldiers and mages, and vulnerable to Tar-Baphon, and her army - her entire world - absolutely cannot afford for Tar-Baphon to learn of Velgarth and take the Empire for his own use.
And…at that point it doesn’t matter, in the long run, if Iomedae herself is too principled to turn back on her promise not to invade, because she almost certainly isn’t the only legendary warrior in her world who is opposed to Tar-Baphon, and someone will decide that the risk of letting the Empire continue to exist is too high.
From Iomedae’s perspective, he thinks, the only thing that matters, here, is that there’s nothing for Altarrin in Jacona, there’s no route to achieve the only aim of his that she has any reason to care about, it would only be - handing himself over as a pawn to a machine ultimately steered by the same gods that the Empire was built to defend against, until the centuries of relentless pressure pared it down to a grinding wheel that can no longer be changed on its course.
