I found a mod for oblivion that adds ship wrecks filled with loot. I guess it depends on one of the overhaul mods for it's unique loots. It's pretty nice, but below a certain depth, the LOD for the lake/ocean floor doesn't vanish when you get close to it. Some of the wrecks are hard to find as a result. Gives me an idea though.
That introduction to shivering isles to. Where you sit in a room with Haskill and then the room turns into butterflies and flies away. If I saw that shit, I wouldn't go insane. I'd fucking smile. Can you imagine seeing shit like that irl? Fucking magical.
