Faerie

Faerie is a magical realm where Stormhold is located. It is located beyond the Wall next to the village of Wall.

According to Neil Gaimen in the novel, Faeria is "bigger than England, as it is bigger than world." The exact size of Faeria is relatively unknown, but it is greatly implying that the land is bigger than Earth. It stretches into different biomes such as a mountainous terrain, woodland, tundra, and an underground cave network.

Faeria also houses magic that doesn't exist on Earth, like the ability for stars to become human, the moon taking the shape of a harvest moon, witches, and unicorns.
