This AU has no further presence online than this page.
Long ago, two races ruled over the world - humans and monsters. One day, war broke out between the two races. In the end, humans were victorious. They trapped the monsters in a part of the ocean and the area was sealed by the 7 greatest human sorcerers. Ships that enter the area are said to never return.
The royal family originally lived on a ship simply called the Ship (Muffet was never good with names and Sans was too lazy to ever suggest anything) but since it was damaged in the war, Muffet hired some of the inhabitants to build a new ship. It was eventually finished and Muffet named it the New Ship.
Years later, Chara ended up in the area and was adopted by the royal family - Muffet, Sans and Saffet. Chara and Saffet became best friends. However, Chara died and Saffet took them back to the humans' land. The humans attacked Saffet so she escaped and sailed back to the New Ship where she collapsed on some flowers and turned to dust. Muffet got angry and decided to kill all humans that entered the area. Sans disagreed and the two got divorced. Sans left and went back to Ship, which he now called Ruined Ship because of its condition. However, he was too lazy to actually repair it.
