Brightcrown Mountains

The northeastern part of the canyon contains the eastern entrance to Stormterror's Lair, which was formerly the capital city of Decarabian's Mondstadt.

Stormterror's Lair was once the capital of Old Mondstadt, ruled by the God of Storms, Decarabian. After he was slain in an uprising, Barbatos took his place and reshaped the land. The people then moved the capital to an island in the middle of Cider Lake, where the City of Mondstadt remains to this day.

Five hundred years ago, victorious but grievously injured by the corrupted dragon Durin, the Dragon of the East Dvalin fell into a deep slumber in the ruins of the former capital. However, the people of Mondstadt forgot about him and when he reawakened; they feared him and called him "Stormterror" — giving the region its current name. This, along with the pain from the poisonous blood clots inflicted by Durin, allowed him to be manipulated by the Abyss Order.

The area is protected by a storm barrier, preventing players from entering until the Archon Quest Hurdle in Prologue: Act III - Song of the Dragon and Freedom is completed.

The Boar Habitat is notable for its unusually high number of Forest Boars.

Decarabian's Tower is located in the middle of the city of Old Mondstadt and is first scaled as part of the Archon Quest Empty Abode. As its name implies, it was where Decarabian, the God of Storms, once resided and overlooked his people.
