The Widdershins Ocean is located far to the southeast of the Circle Sea area. It contains the island known as Four-Ecks or XXXX, which is not in game yet, as well a branch into the Agatean Sea. In the future, it may reach to the Rim Ocean and therefore to the Circle Sea too, in an extended fashion.
On winters, autumns and springs, the western part of the Ocean turns into glacier, with the respective NPCs. Besides this, little is known about the Ocean's NPCs. Info would be appreciated.
