Cyril de Montfort (Son)
Prosper is a high-ranking nobleman in Orlais, inheritor to the dynasty of Ser Gaston de Montfort, who rose to prominence in the Fourth Blight. He is a close personal friend of Empress Celene I. He has a son, Cyril.
Prosper spends most of his time outside of Orlais on business or vacation, styling himself as a duke. He is known for throwing very extravagant parties, and regularly hosts wyvern hunts in his mountain estate in the western Free Marches, Chateau Haine (a former fortress), which his ancestor acquired after the Fourth Blight.
He also appears to be fluent in the Qunari language.

Prosper is the main antagonist in the Mark of the Assassin DLC. According to Tallis, he holds the "Heart of the Many", supposedly a gem which he has no right to possess. Tallis enlists Hawke's aid to infiltrate Prosper's home, the Château Haine, and steal the Heart of the Many.Hawke and company arrive at the Château, having apparently accepted Prosper's previous invitation to the Champion of Kirkwall. After slaying a wyvern during a hunt, Prosper welcomes the Champion into his home. But as Hawke and Tallis infiltrate his vault, it is revealed that Prosper knew who the latter was the whole time and had the two imprisoned. As Tallis explains to Hawke, there never was a jewel. She was in fact after a Tal-Vashoth named Salit, who was going to sell confidential information about the Qunari to Prosper. Instead of plans for weapons or tactical information, however, Salit gave Prosper a list of names, detailing the various Qunari agents in Thedas, which Prosper failed to see the significance of. In the ensuing battle, after the Champion escaped from his dungeon, Prosper was nearly sent off the side of a cliff with his wyvern mount Leopold. He promised that Empress Celene would burn Kirkwall to the ground. Regardless of Hawke's response, Prosper is either way sent falling to his death. However, his threats were futile, as it would become scandalous if it became public knowledge that he was dealing with Tal-Vashoth, possibly on the Empress' orders.
- Prosper shares his family name with the Simon de Montfort, 5th Earl of Leicester and his son Simon de Montfort, 6th Earl of Leicester the former who died leading his soldiers in the Albigensian Crusade; and the latter lead the Barons to rebel against King Henry III, and called for the first directly elected parliament in medieval europe, respectively.
- After the wyvern hunt, Duke Prosper talks about how hunting a wyvern is "a terrible risk. But the prize..." This is a reference to much-maligned line from Mass Effect 2, during a Female Shepard's romance path with Jacob which Mass Effect fans had much fun with.
