In [[490]], Octa and Eosa both waged war against [[King Uther Pendragon]], having successfully beaten [[King Heraut|King Heraut of Malahaut]]. The pair wished to steal Excalibur for themselves, as Octa believed his cousin Eosa deserved a magical weapon as well. The pair were defeated, their army routed, and Octa himself was captured by the [[Characters_(Pendragon)#The Ursine Brotherhood|Ursine Brotherhood]] at the Battle of Lincoln.
In [[493]], the two Saxons escaped from the dungeons of Logres, making their way north. Once there, they brokered an alliance with [[King Heraut de Aprés, the Centurion King of Malahaut]] to attack Uther's lands together.
