Frostglades
The Frostglades are a mana-rich region the size of Selwyn, composed of forests, hills, and numerous lakes and mountains. Pine trees are common.
The name comes from the presence of at least a dozen cold-aspected nodes of snow and ice scattered through the region, resulting in an environment where snow falls even in the depths of summer. It's possible for entire valleys to be buried under the snow. In the winter, the cold grows even more bitter, and few people dare step into the Frostglades then.
Winter fey abound within the borders, from hostile ice gremlins to snowshadows, and that doesn't even take into account the more sinister, intelligent types of fey. Mana storms can strike at any moment, dropping the temperature from its natural state to a magical cold far more dangerous to those caught outdoors… and then there are the magical beasts that live in the woods, such as frostwolves.
Fey are relatively common in the Frostglades, the most powerful of these being the fair folk who call the realm home.
Creatures from the Frostglades sometimes emerge to threaten the nearby town of Waterstone.
