Jacen Gevorian III was a human male and son of Jacen Gevorian II. After his father's death, he took the title of Grad and ruled his home planet of Maynus until his death. He was a more social Grad as he attended more events than his father had. He also helped the research of the Vandoid sickness, though the research was never completed as he cut funding when their government began losing money. He spent the majority of his life in the Gevorian capital of Belaham.
