- "A very smart man of good sense who is somewhat oppressed by the people. Despite his numerous suggestions for the future of Iscalio, none of them have been adopted by the King. Life continues for this unfortunate man."
Ulster is a smart and caring man who is one of Iscalio's top generals. Compared to the other Knights from Iscalio, he is very down to earth, and is often bullied by them because of this. He is the one who does the accounting for Iscalio's funds.
Ulster has a wide jaw, light green eyes, and dark blue hair, most of which is covered by his cap.
