Marlon was an integral figure of the first war against Medeus alongside Anri, Cartas, Ordwin, and Iote. In comparison to the other Heroes, less is known about Marlon but it is known that he was a Noble of Akaneia and younger brother of Cartas who left the country to go to the untamed plains. He won the support of the plains people and after the helping his brother defeat Doluna, he founded Aurelis which his children ruled after his death.
