This is the northern sea of I'Barra, separating Kirhamh and Acoleard from the unlivable ice-and-water expanse of the northern pole of the world. The water of this ocean is purer and clearer than the other oceans, comprised mostly of freshwater, giving it its distinctive dark blue color and visibility through the depths. The Mazarine tends to be the calmest sea, overall, though made treacherous by slowly southern-flowing chunks of ice, many of which are not always visible from the surface. As well, the pervading chill and calm increases travel time by boat greatly, due to minimal water motion and usual lack of beneficial wind direction. Because of this, passage across the Mazarine is kept as close to the northern Kirhamhan coast as possible.
