an introduction about a seaside town that was destroyed by a cataclysm and consequently sunk into the depths of the earth. Rogueport was later built at this site, with the fortunes of the lost kingdom fabled to exist behind the eponymous Thousand-Year Door, located in the ruins of the old town. Peach mails Mario a magical treasure map she had purchased in Rogueport, beckoning him to come. Before Mario arrives, she is captured by the X-Nauts, led by Grodus, who had intended to obtain the map. With the help of Goombella and Professor Frankly, Mario learns that the map can potentially reveal the location of the seven legendary Crystal Stars, which are required to unlock the Thousand-Year Door. Mario then sets out and collects all the Crystal Stars, acquiring new partners on the way. Meanwhile, Peach is held captive at the X-Nauts' base on the Moon. She gradually learns about the X-Nauts' plan, and she e-mails her findings to Mario. Meanwhile, Bowser attempts to steal the Crystal Stars for himself to attempt to take over the world. The "treasure" is the dormant Shadow Queen, the demon responsible for the ancient cataclysm. Grodus intends to resurrect the Shadow Queen by using Peach's body as its new vessel, believing that he could control it and conquer the world. Peach is removed from their base before Mario arrives. Mario unlocks the Thousand-Year Door with the Crystal Stars but is unable to prevent the Shadow Queen's possession of Peach. With the help of the Crystal Stars, Mario defeats and exorcises the Shadow Queen. The game ends with Mario and Peach returning home together.
