Some years ago, on one of the many sites that try to keep record of TES lore, I came across a reference to a deadric item (I believe a ring) that was said to give access to a pocket realm. This item, near as I can remember and tell from recent searches, was either given to Antiochus Septim by Sanguine or Pelagius Septim III by Sheogorath.
Now it seems I am unable to find reference to this item again and can either not find or recognize the site I had discovered it on. My hope is that in the hundreds (if not thousands) of members here, someone will be able to assist me in tracking down this item.
