If you left your castle for more than a week, on a quest or maybe to attend the Pentecostal festivities, several things would happen. They are especially fond of land titles or ownership papers, because Barons are always interested in the acquisition of more land. Why this is, nobody knows for sure. Barons are, for the most part, homosexual bachelors.
Nobody really knows why for sure, except for the barons.
Secondly, saracens would invade the castle and build nests to procreate in. Saracens are hideous winged creatures with protruding, fanged mouths, bull-like horns, glowering eyes, and sizable, razor sharp claws. Try to imaging a cross between a praying mantis, a bat, and a veloci raptor. Terrible terrible things, these saracens. Saracens are sentient and can display human intelligence, like Sir Palomides the saracen from King Arthur's court.
