Dragon Age Inquisition: Hidden areas in Emerald Graves Dragon Age: Inquisition Guide

The above map presents locations that are more difficult to access, which you can visit while exploring the Emerald Graves.

You open the door to Villa Maurel with the key that you retrieve from bandits

Point 1 on the map marks the entrance to the Villa Maurel. It is one of two additional locations in the Emerald Graves. With this one, however, you may have bigger problems. By default, the villa is locked and you need a key to access it. You can find the key on one of the bandits in frond of the villa so, after the fights, loot the corpses.

Point 2 on the map marks the entrance to Chateau d'Onterre, i.e. the second of the additional locations in the Emerald Graves. Unlike in the caves of the Villa above, you do not need to take any additional steps to enter it.
