Shadowlands Marshes of Shinomen

A Shadowlands army once marched through the Shinomen, looking for a route to invade Rokugan. Their corruption awakened a small contingent of Naga, who struck down the army with their Pearl Magic. The taint could not be eliminated, however, and it left a small, corrupted marsh. It is warded by glyphs made by the Cobra to keep the corruption from spreading.
