It was the clan war to end all clan wars. You see, GCCM invaded parts of KC, who didn't have the willpower to resist their stupidity. Soon, Cmen and ARES banded together to form the allied powers. NWB stayed neutral. Soon, all clans were either GCCM-aligned or Allied.
The war was ended when I slayed Chesse20, the leader of GCCM with a battery-powered Airsoft gun.
