Sir Dupre is a long time friend of Lord British, and one of the most loyal knights of Britannia. His valour and courage are admired among all men and women of Britannia, although it must be noted that he has also reputation of an adventurer and loves feasts which include wine and women. It might be that his love of life is what brings him more closer to people's heart, than any other well-known man does in Britannia.
Most of Britannia knows Lord Dupre as the saviour of Trinsic and the purifier of the Felucca Shrines. It was he, who inspired so many people to gather their courage and eventually slay Jou'nar, and his undead minions, which were fortified in Trinsic.
Dupre's most recant actions include leading the loyalist army on Felucca and knighting young hero by the name of Dawn as royal knight.
