Biography
When a Melee tournament was announced in Camelot, Ethan and his companion Sir Oswald made their way to the kingdom. When they set up camp the two knights and their servant were killed by the two thugs Dagr and Ebor. Ebor then put Ethan's blood on an enchanted crystal he obtained to assume his form while Dagr did the same with Oswald. With the identities of the two knights they came to Camelot and fought in the Melee wielding swords that merely appeared to be blunt so they could kill Arthur. However, they were killed by Gwaine, Gaius then revealed their true form (Gwaine).
