The Inquisition was created by the third King of Aeribis, who had been bred by his father and grandfather to be extremely paranoid of his allies and underlings. So, the King began to kidnap children, and have them trained by his top soldiers. These soldiers were different from the normal breed of trooper - these were assassins and spies, loyal to the core to their king and queen. Countless children, stolen from their cribs, were added to the ranks of the growing Inquisition. At first, their primary use was to spy on the nobility, and make sure none would betray the Crown.
But as generations passed, and the crown of Aeribis was given to the next in line, the Inquisition became a more sinister part in the lives of the Aeribissians. Disappearances, assassinations, and exile became more common, even among the peasantry, and rumors of the Inquisition began to spring up. Talk of rebellion and resistance sprung up as well, but nearly all who uttered the words were silenced and found dead in gutters. The shadow of the Inquisition loomed over Aeribis, and none could stop it.
It has grown worse under the rule of Eline I, the current monarch. The Inquisition has, once again, begun kidnapping children of families, especially the nobles, and the noble families have begun to drastically dwindle in size. Many attempt to flee across the border to Conjuska, but even in another nation, the Inquisition reaches out to destroy the enemies of Eline. Her Hounds have run into nations, neutral and enemy alike, to kill and spy. The young Queen uses them like a dagger in the back of her allies, to make sure they keep to her side. And even then, sometimes she'll thrust it into their back, as a warning to the rest.
