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