In the 22nd century, after human caused ecological disaster that destroyed life on earth, sentient AI beings are all that remains of life.
In this desolate future robots live in relative peace, thanks to the implementation of the FUBARs and the Qudos system. The whole economy, from class, status and power is centred around a global system of Qudos standings, and the Oraculus, which records all events that take place in the FUBARs Arena.
In this world where computation is as essential to life as competition, robots have developed a complex warrior society where only through an brutal evolutionary competitive process do the most fit robots survive. This process is competition through the FUBARs arena. Through this competition robots continually improve themselves and earn higher rank in society. Professional FUBARs warriors are called FROBOTS and they are regarded as the heros in society.
The founders of the FUBARs were 5 original robots. These were different programs which evolved into the templars of the FUBARs religion. Each of these templars called "Protos" evolved from original programs written before the emergence of AI. They represent the basic type of templates from which all warrior FROBOTs are derived from.
