There are none. It was a position passed down to his son, and his son, being much younger, had no intention of dying. He also just stepped into this position not more than a year  or 2 prior? Him dying just ... happened? I hate politics, so I never integrated that into the rp.

There is no younger son, so I imagine when the town has a moment to do so, the advisors, and whoever kept his council will discuss what is to be done and who could replace him. His father isn't dead, so he may take up the reign once more if need be.
