The archpriest Willemer, in later annals known as Wilmerius, was a cleric from Vizima and a sitting member of Foltest of Temeria's Royal Council.
He was responsible for capturing, torturing and death of Philippa Eilhart during the witch hunts. Ironically, many years later, it was he who went down in history as a heretic and sectarian, while Philippa was remembered as one of the Martyr Saints.
