From your initial position head west underneath the arches and go through a door where you'll end up in a storeroom with an imposing oil painting.
Can you think of anything more infuriating than being sued by someone trespassing on your property? Instead of going straight up the steps ahead of you, turn left and walk around to the side where you will find a merchant of sorts.
Follow the path down where you'll see a bunch of qunari in the distance.
If you escalate this prematurely, you may damage your relationship with the neighbor and cause unwanted tension.
As you get further in you will find yourself fighting more qunari: three defenders and three spearmen.
Frustrating their nefarious plans is an enjoyable process for the most part, although the very last section, a grindfest followed by a cheap boss, is poorly paced.
