Well, I was reading the http://www.uesp.net/wiki/Lore:Pocket_Guide_to_the_Empire,_1st_Edition/Skyrim when my attention was drawn on the place called Old Fort. It is desribed as having tall walls made with irregular porphyry blocks.

It seems to look like no other place encountered yet in the ES games. But it was alreday old when the first edition of the famous Guide was published. So one can doubt it still exists.

What do you think ? Should it be in Skyrim? If so, my humble opinion is that it would be a great quest related place, possibly hard to find and containing interesting artifacts or items interesting from a historical point of view, such as rare books or archeologic content. But one could also consider that there are only remnants of an long forgotten ruin.

Sure. I'm also looking forward to and hoping that the Labyrnthinian Dungeon is in.

I'm hoping both of those dungeons are in, it could make for an awesome dungeon to explore, especially if the treasure is handplaced.

I'm more interested in the ruins of Saarthal.

Sound interesting... We should make a comprehensive list of all the dungeons we think MAY be in Skyrim.
