Scientists from a planet called Oberon invented a machine called a reality engine. It’s a machine one can use to see through all of time and space, including alternate timelines. People can also use the reality engine to control time.
Oberon is divided into many countries. The country of Libertas won the reality in a tournament against the country of Kratos and they brought the machine to Earth for safekeeping.
Reality Engine is a spin-off of Townie Place.
