Uchuu Densetsu Ulysses 31

Synopsis

Ulysses meets an old scholar named Heratos and his assistant, a young Zotrian woman named Atina. Heratos gives Ulysses a map that he says is to the Kingdom of Hades, but is actually to the Graveyard of Wrecks and Hulks which no-one has ever left alive, because the gods threatened Atina's life if he did not deceive Ulysses. While there, Telemachus finds the black sphere which contains a map of Olympus.
