Return to Ostagar is a commercial downloadable content (DLC) pack for Dragon Age: Origins. During the course of the quest the player revisits the ruins and the battlefield of Ostagar to retrieve secret documents and a powerful armor set worn by King Cailen during the fight. This DLC is very fighting oriented; there is only one dialogue sequence at the start of the quest and one decision at the end. The rest of the mission is spent slaughtering Darkspawn masses which occupy Ostagar.
Additionally it offers a second chance to recruit the Mabari dog if the player missed the first opportunity. The NPCs which participated in the battle offer a few additional lines.
