The Northern Sea is a large body of water in the northernmost regions of Gielinor, past the northern edge of the Wilderness.
How the Northern Sea relates to the Lunar Sea is unknown. Some believe the Lunar Sea is a small portion of the Northern Sea, while others believe they are entirely separate. On the world map, they are obviously connected into a single body of water.
