Lord Gregoire was a Telmarine Lord who served as a Marshal of the Lists for Miraz, alongside his cousins Lord Sopespian and General Glozelle. He plotted against Miraz with the two, but he met his death after Miraz's murder.
He charged at Peter, only to get his legs sliced out from under him, and then his throat cut.
In the Prince Caspian game, he is the second to last you have to fight in The Battlefield of Beruna. The player must kill twenty-four archers, and then defeat his guard, while he is attacking. He must then be injured after certain attacks.
