Synopsis of "The Underworld Part I"
Artemis,  Aegeus  and Arthur move in to a new apartment where they are having fun. However, it ends in Arthur slipping and hitting his head on the solid ground. This causes him to bleed, so Artemis and  Aegeus  call the hospital. Later, Artemis and  Aegeus  are standing by Arthur's side. Aegeus  asks Artemis what they're going to do, with Artemis claiming that Arthur's soul is in a limbo state right now, and the only way to save him is to travel to the Underworld and grab Arthur's soul before it's too late. They travel to the end of the ocean until they find a large cave. They jump in to it, landing in the Underworld. They walk until they get to Styx, a river in the Underworld. There, they meet Charon the Ferryman. They pay him with a coin and he takes them across Styx to the gates of the Underworld. They get off the boat and Charon rows away. However, before they enter the Underworld they have to face Cerberus, the three headed hound of Hades with a serpent's hindquarters. Artemis reveals there is no way to kill Cerberus, and if you do he will just come back in a few hours. However, they do manage to defeat him by making a stalactite fall and pin him. Aegeus  and Artemis then run in the Underworld, not realizing that Hades himself is watching them.
