Located on the southern tip of Antonelle, and by extension Alenthyl, Challax is home to the city of Lavette Rochelle, the headquarters of “Le Croix Pateé Rouge”, and the seat of power for the current ruling house of Antonelle, House Gilbeault. Challax is another place in Alenthyl that produces champagne, albeit to a lesser extent than Calcassonne and Arlenne.
