Buguese survives after crashing Dark Opal into Mantid's fortress and laments that he lacked the power to force Mantid to bring back the sun. Grasshop guides the Spider Riders through the sewers to reach Mantid and the group separates again: Sparkle and Lumen escort Grasshop to visit his family, Igneous and Magma fend off Invectids, and Hunter, Corona, Aqune, and Quake confront Mantid, who reveals he was once an Earthen like Hunter and then summons a ship composed entirely of the Oracle's power - the Ark of Destiny.
