Frostback Mountains
The Frostback Mountains are a formidable, snow-capped mountain range that forms the natural border between the nations of Ferelden and Orlais.
Geography and Significance
The Frostback Mountains serve as a massive geographical barrier in the continent of Thedas, separating the kingdom of Ferelden from the Orlesian Empire. These peaks are notoriously treacherous, characterised by extreme weather, steep terrain, and a lack of traversable passes, which has historically influenced military strategy and trade routes between the two nations.
Cultural and Strategic Impact
Beyond their role as a border, the mountains are home to deep roads and ancient ruins that hold significant importance to the dwarven culture. The range is also notable for being the path taken by the Grey Warden Alistair Theirin and his companions during their journey to gather allies against the Blight. The harsh environment of the Frostbacks tests the resolve of any traveller, including those seeking the hidden knowledge of the Circle of Magi or the clandestine movements of agents like Leliana and Zevran Arainai.
