Did Zodiark ever do anything wrong?

[Cleretic]

Right after Elpis :

• Tell the Convocation instead of playing 14d chess, and reach a consensus on what they should do. If they can't, apply plan B ;

I don't need to read any more of this. You have already shown your hand: you are ignoring what the game says, to claim that the game is wrong about what it says.

This exact point, your absolute Plan A, is something that that game explicitly says is a bad idea. Not only does Venat say that she can't tell the Convocation, we know that's right, because we've already seen it: Emet-Selch is a by-the-books square doing exactly what the Convocation is supposed to do, and he made the problem so much worse that Kairos is the only reason they managed to still have a Zodiark afterwards. If your first point is so easily debunked that the game itself did it, you don't have any other points.

Everything else you said is exactly what I thought: your own imagined scenarios based off of no evidence, because your very first point was to reject the evidence we actually had.
