It was? That means in ob you went to skyrim....
I'm like 99.99999% Sure that Pale Pass is through the Jeralls in the Border regions of Skyrim and Cyrodiil. UESP check time, though since (especially in Fantasy lore) Borders wax and wane over the eras, it could have been Skyrim once, and now it's Cyrodiil, and 200 years later it could be Skyrim again.
