The top layer of Ysgard, called Gladsheim, is far and away the most well known and well traveled of the three layers. Most of the inhabitants live in camps and rugged settlements with rough and wild conditions. The layer is dotted with dozens of huge halls, smoking battlefields, and hilly terrain leading down to cold seas. Few settlements exist along the edges of any of the earthbergs, except those interested in trade with communities on other earthbergs.
Much of the layer is empty space, the Sea of Space, filled with large floating rocks. The rocks range in size from pebbles to planets. Many are inhabited. Most, but not all move. Some even impact each other. Massive, cylindrical rivers run through much of the layer and connect to some, but not all, of the rocks.
