As one of the most powerful noble houses in Krakia, House Bielski has access to large amounts of coin, soldiers and land. Cities and castles in their lands pay taxes directly to White Mountain and are obligated to provide them with soldiers when called. However, as subjects of the King of Krakia, House Bielski pays taxes to Krakgorod and is obligated to release the command of their forces to the king in time of war.
House Bielski was founded by a mage who wanted to protect the inhabitants of his city from bandits and nobles. The Emperor saw that and rewarded him by elevating him to nobility and giving him the title of Warden of Western Krakia.
