In Golden Sun
Alex was one of the last of the Mercury clan, who were in charge of watching over Mercury Lighthouse, making sure it was not lit (lighting the lighthouses would restore Alchemy, which was considered to be a threat, despite keeping all of Weyard bound together, do to people misusing it). However, Alex had sought to restore Alchemy, and ran away from Imil, leaving all of the responsibility of watching Mercury Lighthouse onto his sister, Mia. He eventually met two Mars adepts from Prox who also seeked to restore Alchemy, Saturos and Menardi, whom he joined up with.
