It has yet to be revealed just how long Diemoas was king of City Fractas, but his reign ended the day Hiro-Kala
came to Giausar. In an effort to halt the war started by the stranger, Diemoas challenged Hiro-Kala to a customary duel pitting the two mightiest warriors of opposing forces against each other, and the loser must surrender. Armed with the immensely powerful Streamsword
, Diemoas fought as hard as he could, but his foe’s mastery over the Old Power proved to be too great. Diemoas admitted defeat and pledged loyalty to his opponent, but Hiro-Kala would not be satisfied with anything less than Deimoas' death.
