  Summary

  Interference from the Anomaly had stopped one night, and the universe was free from its reins… Although to some, their fate was unfortunately cut short.

  Characters and assets were cut from the game’s files, causing unexplainable disappearances. From it, the universe became unstable, and began to destroy itself in hopes of restoring balance.

  What is a Sans to do, if his universe started to eat itself?

  Try to save it, of course.

  But what if that fails?

  …

  —————

  Or… Sans somehow invents multidimensional travelling by accident, loses everything, and now has to survive the multiverse to find answers.

  And possibly make some friends along the way.
