Yurugen

Yurugen von Trackia is Katia's father and the current head of the Trackia Duke House, the kingdom's most prestigious noble line. He gives an impression of intellect and looks younger than one might expect.

Because the Trackia and Frenbreed families interacted while the children were young, Yurugen already knew Ermes, and he receives the returned young man in his estate's drawing room, remarking on how he has grown.
