Deserted Building

The 'Deserted Building' comes available ( on the world map) after finding the journal of the dead Templar in a back alley, after receiving a quest from the Chantry Board. The building its self is not that big and is home to numerous Blood Mages, Mercenary Archers, and other enemies. At the end is a boss Blood Mage and several other enemies. After killing him you receive notification of completing the quest.
