This is the second game in the 'Abenteuer Catan' (Catan Adventures) series that started with Candamir: The First Settlers. The theme of Elasund is based on the 'Die Siedler von Catan' novel written by Rebecca Gablé, itself based on the original The Settlers of Catan game. In Elasund, players compete and cooperate to build the premier city of Catan.
