Orks of the Mercatorius System

After the razing of Mercatorius Prime following the Primus Ruining the Orks of Waagh Bonepa were thought all dead. And for a while it seemed that Mercatorius Prime was Ork free. As the Imperial forces began to get complacant, in a ruin of a city the greenskin present began to grow. In this time the Orks were just a disorganized rabble constantly fighting with each other until several Bosses rose up and organized themselves into clans.

The only thing stopping the Orks from being a threat to the entire system was that all the Bosses are too pre-ocupied fighting each other for domince. That is until the Invasion of Mercatorius and the onset of the Mercatorius Crusade. This presented the Orks with an abundance of targets to fight and the bosses stopped fighting each other and decided to pick a fight with everyone else and prove they are the mightiest of bosses.
