The Great Freezing Sea is an area where most of the Polar Sea once was, first introduced Monster Hunter Frontier: New World 4.5. This area was once where the great glaciers and environments of the Polar Sea once stood. Many glaciers in the area are destroyed and their is a barely any movement in the sea unlike how it use to be. Now the Polar Sea is pretty much dead. While in the area, hunters will spend sometime on the Large Exploration Ship as it slowly sinks in the freezing water as Kori-Shan Lung stalks the hunters.
