User blog comment:Ravager134K/my theory on the origin of the chimera/@comment-1788799-20100131190719

I believe that some time before the Great War. This alien created the Chimeran virus as a means to make super-soldiers for their Empire. However, they soon lost control of the Virus and the Chimera rebelled. For hundreds of years, the Chimera were locked in a brutal intergalactic war with Earth being one of they're strongholds. Some time later, the Aliens launched a super weapon against the Chimera on earth that killed all the Chimeran forces and wiped out the dinosaurs. Eventually, after much bloodshed, this alien race defeated the Chimera and launched the Virus and any surviving Chimera into space. For thousands of years, the Chimeran virus stayed sealed on this "satellite". In 1908 however, the Chimeran virus landed on earth via the Tungaska event and we all know what happened from there. However, some Chimera probably escaped to other worlds, still locked in conflict with the Alien Empire. Its possible that the supreme virus that controls Chimera, a variant of which was given to Shepherd aka Daedalus, was placed on this "satellite and once the Virus was released and infected a host, the Chimera were awaken once more.
