Ludon was a crewmember aboard the La Petite Marie, and was referred to as occupying several jobs, including mate and steersman.
Along with Grest and Ricaud, Ludon deserted the ship at Guayama, Puerto Rico.
Unfortunately for Ludon, the crew of the Diablo Del Mar found him near Ponce. Captain Rocco Madrid captured the Frenchman and attempted to use him as a bartering chip during negotiations with Redjack Teal. This ultimately backfired, as Teal sailed off with the Del Mar and Ludon.
Madrid had instructed Ludon to lie to Teal about a vast treasure hoarded by Raphael Thuron. Teal put him to work as a cook's assistant, and Ludon used this role to spread tales and disaffection between Devon Belle crew members. He was eventually discovered, and during punishment with Joby and two other crewmembers, the British murdered him and tossed his body over the side.
