It is mentioned in the popular series of novels A Dance with Fire as the home of a disgruntled Nordic diplomat who was sent to Valenwood. The city was once home to a gladiatorial team known as the Iceblades.
 Jerall Mountains
The Jerall Mountains are a mountain range in northern Cyrodiil, forming the border with Skyrim. They meet the Valus Mountains at the Morrowind border. The largest town in the Jerall Mountains is Bruma, which is connected to the rest of Cyrodiil via the Silver Road and Orange Road. The forests of the High Jeralls provide wood for the region. Dive Rock and Gnoll Mountain are among the few named peaks in the region. The Pale Pass is a secluded pass through the mountain range, but its location was lost after the Akaviri invasion of 1E 2703 and was only rediscovered in 3E 433. Shrines to Azura, Hermaeus Mora and Namira are located high up in the mountains, away from scrutinous eyes.
