Knights of Tezoth

Sounds more like you're buying a one-time effect that lasts until the first attack.

That's crap if so... So some weakling can strip the defense, and against Ardus following right behind, the city is left without protection... Then let there be a choice: use the cancel or defend.

But if it's otherwise, then it turns into unbalanced nonsense where Florenzan will pour a couple of actions into finances and calmly repel up to five attacks per turn, without any harm to the budget.

Money beats evil. Florenzan is a peaceful region. It doesn't want to fight anyone. The Lord made that clear. Bicker among yourselves, but don't touch Florenzan and everyone will be happy...

Well, I have no interest in a conflict with Florenzan either. And your Lord is a good one. But you yourself must understand that from a balance standpoint it looks ridiculous. Even at the bare price, it's a drop in the ocean for Florenzan. And with the discount it's 187.5 gold. Your capital produces 250x2 gold per action while the Lord is alive (and he'll live long, since you'll also be popping the Karnarez defense on cooldown). Without upgrades. So it turns out that with one capital action plus some secondary Knight, you get de facto immunity to attacks. And only to the ones you can't repel. But if you can, the treasury will grow. Or if no one attacks. This doesn't look like an intentional part of game design, but like an oversight, given that your region's income far exceeds that of the others. Though, considering Kanamia's army of Knights, they could do the same there too. Most likely, they will. Anyway... I don't know, if I were Reven, I'd do with Santella's service the same thing he did with the superior equipment.
