- "I increasingly have the sense that I am being watched. Not doubt due to the careless revelation of our true identities in the moronic interview given by B. G."
- ―De Prasi, in a letter to Paul Teragon.
Victor de Prasi was a Frenchman living in Paris during the French Revolution, and a distant descendant of William of Paris, the Grand Inquisitor of France who interrogated and tortured Jacques de Molay after his arrest in 1307.
During the Revolution, de Prasi's friend Bertrand Grimany revealed his own relation to the Inquisitor Philippe de Marigny to a city newspaper, much to de Prasi's irritation. Shortly after the article was published, both Grimany and Paul Teragon, a mutual friend of the former, were killed by Anne de Molay, one of Jacques de Molay's living relatives. After the murders, Anne attacked de Prasi, but he was able to fend her off and wound her before she fled.
As he investigated the double murder, the Assassin Arno Dorian questioned de Prasi, who pointed him in the direction his attacker had fled. Arno then found de Molay and solved the case, and de Prasi eventually recovered from his wounds.
