This expansion contains 3 additional Inhabitant Cards (2 of each) and 3 rule cards.
Currently, they are available inside the box of the AEG edition and as a separate card pack from Board Game Circus (German version). It will be sold separately by EmperorS4 and Board Game Circus at their booth at some events like Essen Spiel.
Add the 3 new types of Inhabitant Cards into the basic 7 types (a total of 10 types), and randomly choose 7 types of them. Place them following the Game Setup as base game.
