Kill the Qunari is a side quest in The Darkspawn Chronicles DLC for Dragon Age: Origins. This side quest concludes the Assault on the Palaces main quest.
Walkthrough[]
Once you are finally able to reach the eastern gate to the Palace District, the Archdemon will warn you that a Qunari is guarding the way. On the way up the stairs to him you will find several ballistae. There is a choice of two staircases, it may be easier to take the northern stairs. Take out the enemies (this area also has the bug that makes enemies re-spawn endlessly). You can use the Shriek's stealth ability to facilitate the slaughter of the enemies controlling the ballistae at the top of the stairs.
Once you get past that area, a good strategy for the next part is to move to the base of the stone tower and keep luring enemies towards you. Sten is protected by two Steel golem bodyguards and a significant number of dwarven soldiers which can overwhelm the party if attacked as a whole. Eventually Sten will charge to attack you with the Golems. Keep moving around the stone tower, healing as needed. The Walking Bomb spell can be very useful if used with caution.
