A world on the far edge of the Beta Galaxy. Hundreds of years ago, a colony ship crewed by space-faring humans landed on PHX010, and attempted to build a colony there. Initially, things went well, and with the help of Reploids, machines made in the form of men, the colony thrived. Unfortunately a plague of unknown origin wiped out almost the entire biological population of the world, leaving only the Reploids and a handful of humans.
Suddenly finding themselves without duties, the Reploids built a society of their own. The few surviving humans on the planet are now respected advisors and cherished progenitors of the Reploid race, but it is the Reploids that are now in control of the planet’s destiny. That society now flourishes on PHX010.
The world of mechanical men is not without strife, however. One Reploid, called Omega, contracted some manner of technological virus. This “Omega Virus”, as it is called, causes an infected Reploid to exhibit uncontrollably violent behavior and psychosis. Omega has managed to infect hundreds of Reploids, and a permanent state of war now exists between the ordered forces of the Reploid Congress, and Omega’s “Reavers”.
