Matthew was a resident of Ealdor. He held back rations from Kanen when the brigand raided Ealdor, and was given a week to make up the missing food. He refused to give up the additional food on Kanen's next visit, and was nearly killed before Arthur, Merlin, Morgana, and Gwen arrived.
He later trained with Arthur to fight against Kanen's brigands, but Arthur recognised Matthew's lack of fighting skill and reassigned him to organise sentry duty and watch for Kanen's arrival to warn them. Matthew was later killed while on patrol, and his horse returned his body to Ealdor, where Arthur found an arrow pinning a note to his back reading: "Make the most of this day, it will be your last". It was his death that made Merlin's childhood best friend Will hate Arthur even more (The Moment of Truth).
