Stonebreakers

Overview
The Stonebreakers, or "Brotherhood of Stone" as they are formally known, are a combination of several Brotherhoods of Demiurg which occupy two Stronghold Class Vessels and several Bastion Class Vessels. The Brotherhoods which combine to make this alliance have become tightly linked through marriage and trade deals to ensure they remain a powerful stand-alone force. Although they trade with and work as mercenaries for the Tau, the Stonebreakers do not serve the Empire while still being allowed access to the Tau territories. Despite being a passive race, this particular group of Demiurg have made advancements in not only mining but also in weaponry and exo-skeletal armour to make sure they can handle almost any threat that arises. Due to being a moderate sized force of Xenos the Brotherhood of Stone are viewed as a threat to the Imperium and come under attack on many occasions.
