Talk:Sulcher's Pass (quest)

I didn't pay for DLC or anything but I still have acsess to Felix. Does that mean I can do the quest? I bought the game second hand, and the one-time use code didn't work, so I presumed the original owner used it. But I can go to the pass and talk to Felix, although thanks to falty internet connection, I can't see weather or not I can start the quest. If I have accsess to Felix, can I?
