  Summary

  We all like crossovers, right? They couldn't possibly get out of control...right?
  After a chain of events lead to Sonic and a few others getting assimilated into the world of XTale, many changes occur as the rules of the Omniverse change to keep itself stable, which sets off a chain reaction that will change reality forever.
