Eight hundred years ago, The Empire ruled a world united by the power of despotic arcanists led by the embodiment of magic, the eldritch-flesh god known as the A’trus.  A rebellion led by The Seven fought The Empire, a war that culminated in the final death of the A’trus and broke his tyrannical hold over the world.  With time, The Seven became known as gods themselves, the patrons of the Reliquis faith, while arcane magic was forced underground.  Seven hundred years ago, one of the first orders of the Reliquis church, The Order of Thorenheld’s Acumen, secretly gathered dozens of the world’s most malignant artifacts of The Empire and locked them away in a fortified warren on the edge of the then known world, locked behind magically sealed doors for all time.  Yet as the centuries passed, the land around the vault became a swamp and absorbed the warren into it.  Populations grew and prospered, expanding to all corners of the world, eventually building upon the swamp and these warrens, covering them with the trappings of civilization, a city called Greytower in the duchy of Falconmoor.
