From the post:
As a brother of the Night’s Watch, you are the stalwart guards for the kingdoms of the south. You do not play the game of thrones, but that does not mean that you are free of ambitions. The Order seeks a new Lord Commander, and you and your brothers are now in competition to prove that you are the worthiest of the post. To accomplish this, you must improve the failing infrastructure of the area south of the Wall known as the Gift, which provides the Night's Watch with resources for the coming winter, and man your section of the Wall against the gathering horde of wildlings who seek to invade Westeros.
The resources you harvest from the Gift will provide you with the ability to build and purchase unique boons that can offer you advantages over your competitors and bring you closer to victory. In our last preview, we looked at the heroes of the North and the abilities they can lend to your pursuit of power. Today, we are pleased to offer you a closer look at how to earn victory points in A Game of Thrones Catan: Brotherhood of the Watch!
