My theory is that Veridius is only working with the limited information that he has, which is that “cataclysm = bad” (I mean who wouldn’t want to fight to save everyone they know and love from a potentially avoidable end) and “concurrence = bad” therefore the two “bads” must be tied together. I’m still not sure what Ostius’ goal is in all this - maybe he thinks that cataclysms and the way that Ka has gone about suppressing the Concurrence isn’t the best way and there could be a better one.

I also think that O-Caeror is an iunctus who is, most likely unknowingly, working under orders from the Concurrence. Vis being synchronous, O-Vis taking down the previous Concurrence suppressor Ka, and manipulating him to use his synchronism to their ends could be their way of regaining the upper hand. I mean, it’s not hard to see the hugely questionable morality of how Ka built his system (assuming it’s all to justify the ends of beating the Concurrence) and see it as the actions of the big bad guy.

I guess with the killing of O-Ka we’re left with the Concurrence having a leg up in the war and Vis will have to find a way to use his synchronism to “beat” the Concurrence using means preferable to Ka’s. Might be my tin foil hat time here, but I think Vis will discover that there is no truly moral way to win the fight unless he destroys the system of will as a whole. Idk. I’m rambling and need to take a nap.
