Ring Lake
located near the High Castle on Jomark, this natural lake was formed in the crater of the ancient volcano housing the High Castle. The castle itself was situated nearly 400 meters above Ring Lake, affording a spectacular view of its brilliant, blue waters. It was named because the waters of the lake surrounded a single island, creating a ring of water in the crater. This small island served as the base of operations for Grand Admiral Thrawn's Imperial forces, sent to Jomark to protect Joruus C'Baoth during his attempt to capture Luke Skywalker, some five years after the Battle of Endor.
