Castle of Bones

The master of the Castle of Bone went out into the world. To the assortment of bones, hundreds of thousands, he intended to add one more of a type not yet used, just as his predecessors for centuries had done. He traveled from city to cemetery, not by any means ignoring pastures or the wilds where strange beasts chose to die. In every instance, the catalogue informed him the material had been used already.
Down rivers, across lakes, and over mountains he ventured, under them too, though none of their names did he trouble himself to learn. Outside one city, a funeral was underway as he passed. The matter had no interest for him since nothing but a man and woman were being interred. He inquired nevertheless on account of propriety, something necessary for the castle's master to guard. He was informed that he witnessed the funeral of a local man and his wife, both blameless. Hearing that, he requested a bone from each and was not refused by the heirs because the master's influence extended even as far as that, and farther.
He returned and increased the castle's size with materials he thought impossible to acquire, the bones of blameless people, whereupon the Castle of Bone vanished. With his powers he perceived immediately the castle was becoming the foundation of a new world, and from that he realized the proportion of sin and virtue is even such in every world there is.
