In Der Pleierís Garel, the King of Kanadic who went to war with Arthur because Uther Pendragon had slain Ekunaverís father. He sent his giant Karabin to deliver a message of his hostile intentions, and he promised to invade Arthurís lands after a year.
During the year, Garel, one of Arthurís knights, raised his own army and defeated Ekunaver in Kanadic. Arthur was surprised to find that the war had been won without his participation. Arthur forgave Ekunaver and gave him a seat at the Round Table.
His name is reminiscent of Escant of Cambenic in the Vulgate Cycle.
