Adaman Fortress really wow'd me. It's an excellently constructed and amazingly beautiful castle set just over the Brena River, with a rather large bridge to get you over and conveniently placed map marker for easy navigation. Although trivial that someone should just hand over the castle to the next person to walk in there are several hints to look for the lost graves of the original Nexus warlords, which I indeed found! I think the thing that struck me most about the castle was that I don't think Bethesda could have done a better job; it was seamless, well thought out and it didn't feel empty like a lot of large buildings in Oblivion (mods or otherwise) can, mostly because there are guards galore all around the castle. The archers lined up on the battlements were always nice to see. I would love to see this mod updated with some awesome quests.
