The White Gold of the Marshes

Trez teleports to 1695 in Doussard, at the far end of Lake Annecy. Salt is worth its weight in gold and a young smuggler, Bastien "Le Renard", needs his help to save his cargo from the Baron's soldiers. Help Trez unravel the secrets of the marshes and outwit the traps!
