The Odd Ensign is a side quest in the Mark of the Assassin downloadable content for Dragon Age II. This quest is only available if you bring Carver Hawke as one of your companions.
A chavalier's pennant has been found. Be on the lookout for others.
Acquisition
This quest is obtained inside of Chateau Haine. There is a pennant hanging on a wall in the Chateau. Taking the pennant will trigger some dialog from Hawke and begin the quest.
Walkthrough
There are a total of three pennants you need to find.
1. Chateau Haine - West on the map in the Chateau. At the top of the Stars just past the cook's alcove where you pick up the quest Hard to Stomach. This one is red & black.
2. Chateau Haine - The Great Hall Gallery. You know you're in the right place if you overhear a conversation between 2 people in regards to the cheese tasting of Despair. This one is blue and triggers more dialog from Hawke.
3. The Dungeons - The Middle of the map in the northern cell (off of the large southern room where you fight the harlequins). This one is tan and triggers dialog from Carver.
Result
Once the third pennant has been found a treasure cache will be marked on the map. Its location is found in The Retreat.
