Anglais - This expansion pack contains additional material for some scenarios, which could be played until now only with some handicraft work. It includes material for Die Wüstendrachen/Wüstenreiter, Der große Kanal, Verwunschenes Land, Die Schatzinseln, and enough material for Groß-Catan, so that you no longer need a second base game for it. Plus, there is a new scenario, Aufbruch ins Ungewisse.
