Errik promises Tessia that he will do what he can to protect the border leys from attack. And apologises to Dakon when Takado attacks.
Errik eventually joins the army trying to repel the invaders, and follows them into Sachaka when they decide to invade. He talks Emperor Vochira into peacefully giving the land of Sachaka to them. He left Lord Dakon and Lord Narvelan to become the first Kyralian kings of Sachaka - who were also the last.
