Asheron Realaidain is a Yalaini mage and central character in the story. He rediscovered the lost art of planar magic and with it changed the world of Auberean forever. His research in portal magic inadvertently lead to the demise of his people, thanks in part to Gaerlan for leaving a gateway open on the Olthoi home world. Virindi tampering would later lead to portals appearing on planets that the Yalaini had once explored, including Ispar.
