Just a warning for those playing Dark Souls who do not have the DLC yet, the game straight up keeps you out of your save after playing on a console with the DLC.
I accessed no part of the DLC, I was at a middle part of the game. I had forgotten entirely that my friend even had it on his console.
This is kind of a dumb way to handle it, I think. With Dawnguard it just tells you you cannot access the content, which seems logical. Locking me out of my save game until I pay $15 does not seem logical at all.
