The Odyssey is hit by a giant column of light that sucks it into a strange space station covered in pyramids. There Ulysses and the children meet the Sphinx and his daughter. The Sphinx gives Ulysses a riddle to solve. If he can answer the riddle correctly he is free to go on his way, but if he is incorrect he will be given to the Sphinx's daughter. She is contacted by Zeus and becomes determined to have Ulysses irrespective of whether he answers her father's riddle and so she tricks Telemachus into entering a forbidden area of her father's realm - which houses the Mirror of Truth.
