Lake Dark is a lake in eastern Karrnath named for its pitch-black waters. The towns of Lakeside and Irontown are located on its shores, and share the lake with other smaller farming communities. The lake waters lie in a depression south of the Icetop Mountains, with the Iron River feeding into it.
Lake Dark is also a manifest zone connected to Dolurrh. Many Karrns believe that the lake's waters provide a gateway to speak with the dead, and that spirits haunt the mists above the lake. This connection has attracted the attention of the Emerald Claw.
