The Duke or Earl of Cambenic in the early days of Arthurís reign.
With a number of other kings, he revolted against Arthur. Eustace pledged 5,000 mounted men to the first rebellion and fought in the battle of Bedegraine where he suffered a defeat. The rebellion was eventually curtailed by the Saxon invasions. Escant fought alongside King Clarion of Northumberland and had a few successes, but a crushing defeat at the battle of Clarence led him to ally with Arthur so that the kings could expel the Saxons for good. Escant had a hand in their defeat at the second battle of Clarence.
According to Vulgate II, this duke's name was Escan, and Cambenic was a rich and prosperous city.
