this page right here, plus it changes some stuff from the original Undertale.)
30000 BC: Past life of Queen Hippolyta, a cavewoman, is murdered by a caveman after trying to offer compassion. They were married at the time and she was pregnant. Her soul then travels to the underworld.
1300 BC: Circe was a princess of Colchis, but according to her own words, her subjects objected to her killing her weak husband. Driven out of the kingdom, she found refuge on a small island Aeaea and began to accumulate considerable magical power, yet it was limited to the island. She used the Sirens to lure seafarers to the island. A convocation forms in the palace of Zeus on Mount Olympus. Artemis, Goddess of the Hunt petitions Zeus to create a new race of warrior women that will help to lead humankind back towards faithful worship of the Gods. Ares, the God of War, believes this plan to be pitiful and will only serve to weaken the vitality of the Gods. Zeus has no interest in the idea at all, and leaves the chamber, allowing the other Gods to decide the issue amongst themselves. Shortly after, a plan to destroy humanity caused by Ares is stopped. Artemis addresses Zeus' wife Hera and asks for her blessing in this endeavor. Hera warns her to tread lightly, and to never again ask her to take sides against her husband. Artemis gathers several Gods sympathetic to her cause together including Hermes, Demeter, Aphrodite, Hestia and Athena. Without Zeus' knowledge, they book passage across the River Styx to the Cavern of Souls. The Cavern of Souls represents the womb of Gaea the Earth-Mother and is a swirling maelstrom of disembodied spirits. The Gods pool their resources, extracting the souls and reincarnating them on Earth while mixing human gametes to make ovums, and then adding sperm. On the shores of Greece and the Aegean Sea, the spirit light of thousands of women are reborn as a warrior race of Amazons, thanks to the ovums planted there. One spirit however, is not reincarnated and remains behind in the Cavern of Souls. Athena notes that this one has a special destiny, and that her time of rebirth has not yet come. Athena addresses these newly born Amazons and tells them that they are a chosen race, born to lead humanity in the ways of virtue. Athena selects Hippolyta to serve as Queen of the Amazons, with her sister Antiope acting at her side. Hestia, Goddess of the Hearth, forges them a great city and the Amazons live in prosperity for centuries, watched over by the Gods and Goddesses for the first few years of their lives.
1000 BC: Feeling threatened by their existence, Ares convinces Hercules and his friend Theseus of the Athens to seduce the Amazons' two queens, Hippolyta and Antiope. Hercules then enslaves the Amazons, steals Hippolyta's girdle, and departs, but not before raping her. Then Ares stops by nine months after Queen Hippolyta gives birth to the first Amazon Halfling who is Aeson, the son of Hercules and rapes her, causing her to give birth to HIS Amazon Halfling Son, and the second Amazon Halfling, Thrax, another nine months later. The Goddesses enhance the bodies of the Amazons, giving them the muscular and busty bodies that they have today as well as additional abilities such as size change, but Hippolyta frees them and they massacre Hercules’s army. Antiope then leads an army on Athens, and Theseus, unaware or repenting of what happened, asks Antiope to become his queen, which she accepts. However, his wife Adriane, prompted by Circe, murders Antiope, but Antiope comes back to life seconds later, defeating Adriane. Hyppolyta's faction moves to Themyscira while Pythia's faction renounces the Gods of Olympus and found the city of Bana-Mighdall. Queen Hippolyta has the sperm that would soon be Diana, Drusilla and Nubia inserted into her by the Greek Pantheon, who also add their DNA and powers and the soul of the unborn child of Diana’s past life, plus two other souls that remained in the cave, thus giving the soon to be born children the same powers as the Amazons and the Greek Pantheon. Sure enough, Diana, Drusilla and Nubia are born.

Shortly after, they come across Inkasisa who had been revived by the Amazons, just like Zukela was and during that time, Arthur is converted to a cyborg by Cyrex MKII and defeated. After his Amazon genetics are removed, his dark side returns, even though his female side somehow had been destroyed due to being an incomplete soul and just a separate persona. Even after he dies, he gets revived along with his female side by Viracocha, the Incan god who had formed everything and then Cyrex MKII now known as Cyrex MKIII stages an assault, only to get beaten. Other events include Christmas with the girls that Arthur loves, after fighting a girl that he raped who gets turned into a demon, but stays as an Amazon forever…
