This expands the landscapes to make it so the shore of the icy water can be really any shape. This set has a ton of corner options, letting you really create nearly any shore line you want if used with the tiles from last month's release. There are 11 corners in all, both convex and concave.
Also, included a photo of the paint job I have started on the broader set. Doesn't show the shore at all yet, but should give you an idea of the scope of the landscape set.
