Dragon Age: Inquisition's first single-player DLC, Jaws of Hakkon, was released a few weeks ago, introducing a new region and storyline to the game. The new area, Frostback Basin, both beautiful and challenging, is recommended for level 20+ characters and can be reached before or after the completion of the main story. Avvar—friendly and not—are the primary inhabitants of the region and are whom most of the quests end up involving.
In the DLC you'll embark on a new main story adventure to discover what exactly happened to the last Inquisitior, Ameridan, who had disappeared 800 years before you took the post. Numerous side-quests will involve gaining the trust of the friendly Avvar at Stone-Bear Hold, pushing back the threat from the unfriendly Avvar calling themselves the Jaws of Hakkon, and furthering the inquisition's discovery and foothold in the region.
