Deadlands: The Flood
The Whateley family is a closely connected family of sorcerers, hucksters and wielders of black magic all across North America. Their roots go back even farther to Europe, though they all uprooted to America sometime in he last century.
The Whateley's are rich, inbreed, insular and dangerous. Many of them are deformed, mentally and physically. For those in the know, they have a better knowledge of black magic than anybody else. And they have the money to hire their own, personal private army that rivals forces owned by some of the Rail Barons.
The family has enclaves all across the West, all working on different plots. In the Maze, their stronghold is in the town of Gomorra, where they live out of Whateley Manor and genially terrify the local population while manipulating the government. The leader of this branch is Wilhelmina Whateley, the matron of the family, though Nicodemeus Whateley deals with the day to day business. James Whateley is his right hand man. Ol Nic' really seems to want his cousin Bonnie to come visit in Gomorra.
