Phillipe travelled to Charouse and applied to become a musketeer. He met the heroes (including his sister Reinette) while he was still in training and was able to provide some limited information and aide.
Later when the heroes confronted Sir Bors in Avalon they received help from Armande Le Pancaque in the form of three skilled swordsmen - Armand, Porthau and d'Aramitz. Phillipe, having now taken the sword name 'Gascon' followed them and helped deal with Sir Bors' guards.
He is now a fully fledged musketeer who primarily serves in Charouse.
