Mountain Mass Island
This island is located in the far north-west of the Island Nations, isolated from other islands. The island has a sandy beach but following the narrow roads that stem from it will lead visitors on a winding trail through the steep mountains.
Due to its inhospitable terrain, it was used as a hiding place for treasure and so many valuable items could be found on this island.
