Chapter 2: Dust
Diana notices her Mother seems melancholy and Hippolyta tells a story that she was reminded of after seeing Vanessa and Julia on a horse. When leading a squadron of soldiers back to the Capital City they met a man, a young girl and her mother. The woman was Queen of Lemnos and was badly scarred. Hypsipyle, The Lemnos Queen, tells the tale of how the women in her city killed all of the men except for the Queen's father.
The Captain of the Argo, Jason, arrived and his men and the women of Lemnos had many children. The Queen and Jason, had a boy and a girl, Phythia. Jason refused to give up his quest and without explanation left Lemnos. The Queen was blamed and all of the men were slaughtered including her father and her son. She was cursed with aged and rotting flesh and banished from Lemnos along with her daughter, Phythia.
Hypsipyle begged Hippolyta's sister, Antiope, to escort them back to Lemnos where she may be rid of the curse. Antiope agrees and Hippolyta stays behind to Govern Themyscira. The Former Queen Hipsipyle leads them up to the city of her youth. A Harpy attacks the women and Antiope orders it killed.
Reaching the city they discover it in ruins. Skeletons litter the ground. The women of Lemnos had killed each other. Hipsipyle's chest tightend and she dies. Antiope takes in Phythia as her own. Hippolyta learns that any society based on prejudice and violence will surely crumble.
Chapter 3: The First Statue
Diana soars over the city and lands near the Temple Of Hades. A Shrine honoring the Amazon dead. Vanessa wonders about the first statue, Egeria, Themyscira's first Captain of the Guards. Diana translates for Phillipus as she tells Vanessa the story.
Egeria with Phillipus as her Lieutenant were charged with gathering lumber. Phillipus hears something and takes off on her horse after noticing black smoke coming out of Doom's Doorway. The Island rested on a dungeon of demons and the boulder covering the cave wasn't enough.
Her horse inhales the black smoke and becomes evil. The evil horse bucks Phillipus off and starts to trample her. Egeria orders the Amazons to block the entrance as she deals with the trampling horse. She slices it's head off with her ax and drags Phillipus away from the now cracking boulder called "The Great Stone". Egeria braces her powerful body against the stone as it burns her. She orders the lumber released and her sisters reluctantly agree. Tons of giant logs tumble and smash into her killing her and blocking the entrance. Phillipus became the new guard after an elimination tournament and her first duty was to build a permanent seal to Doom's Doorway.
They honored Egeria with a warriors funeral and a memorial statue. Philipus explains that through the years they've had to erect other statues. They come to Diana Trevor's statue, the only outworlder to be so glorified.

Chapter 5: Flight of the Icarus
Sitting around a fire on the last night of the Kapatelis' visit, Hippolyta wonders why Steve Trevor didn't come. Diana tells her Steve is busy with his new job as a safety inspector for military aircrafts. Diana tells a story of when Steve was called to investigate a recent crash that his girlfriend Etta told him about. Steve concluded it was sabotage.
The man who hired Steve needs a new plane tested but all the pilots were reluctant. One of the pilots, Gordon Hall, was the main protester. The plane's name was Icarus and Diana recalled Mnemnosyne telling her the story of Icarus. Steve volunteers undeterred by Etta's protests. He meets with Wonder Woman, who accompanied them, later that night and asks for her help.
The next morning Steve takes off with Etta watching in the tower. Then Gordon Hall is seen with another man named Corbin, rigging the plane and Steve loses control.

Steve radios them and tells them he can't eject. Diana goes out to help him while Etta works on getting the controls back. Steve asks Diana if she remembers what he taught her even though he isn't sure if she can hear him. She grabs the plane's metal nose and spins turning herself into a propeller.
