Quake reveals a prophesy concerning eight Spider Riders defeating Mantid and that Quake (after Aqune rejoins them) is the eighth. Mantid gives Buguese control of his new creation, Dark Opal, and commands him to attack the Spider Riders with Aqune. However, when Hunter, after failing to reach a peaceful resolution, tries to use his Oracle Keys, their power is stolen by Dark Opal and given to Mantid, who is using Aqune to prevent Buguese from betraying him.
