Nysdra Sea
The Nysdra Sea, sometimes called the Sea of Nysdra or Nysdra's Doom, is a body of water set between Crona Proper and Cusinaut. It is separated from the titanic Ocean of Cathay by means of a straight called the Northern Approaches.
History
Formation
At some point, it appears likely that the Nysdra was an inland sea, allowing for peoples to cross easily between the Varshani Highlands into Cusinaut and vice versa. At some point, rising oceans and poor soil support and quality lead to the sea being opened up to the ocean, the land bridge eroded, and the inland sea salinized, leading to the extinction of much of the the original surrounding neolithic populations that relied on freshwater fish sources for food.
