Gareth is the mechanical engineer in charge of maintaining the Heimdallr, the fastest airship in Sellund. His skills are certain, and he stands second to none in his work. He supports Ix Nieves and Mileena Weiss's travels, sometimes giving them advice as an adult. He works directly under Gefion's orders, and is indebted to her for giving him a new arm.
