Rundle was Vendel's father.
Rundle looked almost identical to his son. Rundle was light tan with large horns and long, orange hair and a beard.
Rundle spent most of his time with his son and reading books. Rundle helped Deya find Merlin. Later on, he was trying to find his son, but then he saw his son fighting Gumm-Gumms. Vendel was about to be killed, but then his father sacrificed himself by blocking the way and died. Vendel went home and he saw the Heartstone staff with a note on it that says "Take care, my son".
