The rooks started the war. The knights were pushing forward in their territory . The rooks realizing their land was being taken, confronted The knights with a deadly attack. A war erupted. Pilots trained and fought. Troops battled losses but strove to take more land. The bishops recognized the tyranny but insisted on staying out.
Both sides realized that they needed bishop support. Knights and rooks subsequently offered bishops planes and tanks to aid them in the war. Neither side realized bishops had promised to help both sides. The bishops liked the knights more and aided them instead of keeping their promise to the rooks. The rooks realized what happened and sent a massive hoard of planes, tanks, and troops to punish the bishops for lying about their promise. The hatred of bishops had begun for the rooks.
One day, late into the war, rooks had lost most of their land. Rooks were suffering from mass hoards and production and equipment were running low. A very intelligent rook general named Shawk realized they had to somehow get the bish to help them. He struck up a deal with the Army of Muppets, a bish squad full of outcast ( seemingly crazy but some of the best pilots) who were tired of the taking orders from their bashful king. They set up a sabotage attack on the knights. Many pilots were killed, knights suffered major losses. The bishops king said he had no idea about the attack and did not plan it. The knights didn't believe him and started massive raids on the bishops. The hatred of bish from the knights had started.
The rooks recouped themselves and got their bases back ready for action. They wanted their land back on both sides. While the knights and bishops were fighting rooks started to take their land back on both sides with small victories.
The battle for land and the the battle for hatred lives on. Many pilots have been killed and much of the land has been fought on. One thing is for certain. Neither team will settle for their own land to diminish. This war is still not over. And it may never be.
