Pretty good DLC. The scenery is beautiful. As Gerlat said, the place feels like it's straight out of a fairy tale. The story is pretty cool, with a lot of captivating side quests.
In terms of ending, it's absolute bullshit. Beside Regis and Dettlaff, all other characters are utterly unlikeable. There's no satisfying ending where I felt good. But alas, I had to choose one. I went with, which is considered the “bad ending” by many, but for me, it was the best out of all the choices.
