Into the West
The Three Conjurers
When they raided Fellheimer’s Folly, the posse fought and defeated a conjurer and alchemist named Von Stroessner and Margorondu, the demon he had summoned. Upon searching his laboratory, they found his journals, in which he references two associates: Berlitz, and Renke.
With the help of Sam Hellman, the posse managed to track down Berlitz. They found him holed up in a derelict mansion in the northern reaches of the maze, where he was apparently reanimating corpses and summoning the spirits of the dead. The posse put an end to that.
The third conjurer, Renke, is supposedly the strongest of the three. Von Stroessner and Berlitz were both attempting to discover the secret of Renke’s power in their own way.
