Sepulchra

Sepulchra is a world born from catastrophe.
In the early 14th century, the Great Cataclysm fractured reality, separating Earth from another version of itself. While Earth continued along the course of familiar history, Sepulchra was transformed.
Passages to other realities opened. Strange beings crossed into the world. And from deep within the earth emerged Ahman—a mysterious spiritual substance that would reshape civilization.
Centuries later, Sepulchra has become a world of Victorian-era technology, supernatural forces, ancient magic, secret orders, and creatures drawn from realms beyond its own.
This is the world of The Bone Harvester.
