Van Richten
He was born in Rivalis in Darkon in 671 BC. He took medicine at the University of Il Aluk, completing his four or five year program of study in 693 BC. This humble man was spurred into a life of monster hunting when his son Erasmus van Richten was kidnapped by the Radanavich clan and sold to Baron Metus. Metus turned Erasmus into a vampire groom and Van Richten was forced to slay his son. In revenge, Metus killed Rudolph’s wife, Ingrid van Richten. Van Richten eventually slew Metus, and then, with the help of Azalin, the entire Radanavich tribe.
