MonsterTale is an AU of Undertale Rho that takes place on the Surface. Before the time that the Human-Monster War took place, Monsters struck out against Humans, leading to many wars between Humans and Monsters. Eventually, throughout time, the Monsters took a great majority of the surface world of Earth, and the remaining Humans retreated to the last place on Earth that was relatively safe for them.

  • Xin was originally supposed to be named Qin, but due to a mistake done by Alphasaith, it was made to be Xin.
  • The Aster Empire is able to hold so much territory with hostile empires close by because of their extreme industrial might.
