'You can start the DLC at the Grand Chapterhouse in Stonebridge, after you have reclaimed it for the Legion. Talk to Oswalt who will be waiting for you in the entrance hall. You will find an alternative entrance to the DLC in the causeway hub, after you have completed The Spire. If you have already passed that point in the game, you can return to the Causeway Hub by loading "End [Character Name] (e.g. "End Lucas") from your save game list.'
