This is the story of a man named Amasa. One day a bunch of butterflies came to Amasa to take him on a journey to Hierusalem – the land of the dead. On the way he met a man who told him the key to getting into the city. The man explains to Amasa that Hierusalem was built and sealed off from the rest of the world to keep an evil dragon from going out and killing people. The man also warns Amasa that if he kills a butterfly he will live forever. When Amasa arrives at the city he finds out that the people who live there expect him to kill the evil dragon and save the queen. Amasa says that he is done with quests and then kills a butterfly. Soon after that, the evil dragon goes to the queen and impregnates her. When the child is born, the butterflies tell Amasa to kill it but he cannot because the child is so beautiful. When it grows up, the dragon woman begins mating with Amasa creating many new dragons to send out into the world. Amasa tries to kill himself to stop her, but discovers that he cannot die.
