This has bothered me for years and it's time I got an answer.
Back when I used to play Morrowind I stumbled on a large stone door somewhere in the wild (mountainous/hilly region if I remember correctly). When I tried to enter it, it gave me a riddle or message and I was unable to get in.
What door was this? How did other players get in? What was beyond the door? Can someone link me a reference to it?
