A Discovery of WitchesEdit

Shadow of NightEdit
Peter receives a letter in Hebrew at a library in Prague. The letter has secret information about events connected with Ashmole 782 that took place while Diana and her vampire husband, Matthew Clairmont, were in Prague a long time ago. Peter consults with vampire Gerbert of Aurillac about the connection with Matthew's family, and says that he will lead a raiding party of witches on the family's stronghold.
