Knights of Tezoth

He fights for Nosy. Which means either he's already done something, or he's been promised something under the tail for his loyalty.

The regional lord, whose knight he is, ordered him to serve her while he was alive...

Serve, you fool, and you'll get a furry badge insignia.
And the fact that she's destroying what the lord built and supported — doesn't that bother him? So he really is a fool.

The Lord of Swordgard has spent his whole life protecting Tezoth. Renavan comes and tells the heiresses, "Protection is for suckers, let's conquer it instead." What destruction are you talking about? On the contrary, he's trying to stop the region from becoming his antithesis.
