I haven't played Oblivion in years, but I had a fairly epic mod collection when I quit playing. One of these mods provided an immersive and alternate way of discovering the DLC houses, rather than the immersion-breaking quest notification that pops up as soon as you load the game. Does anyone remember the name of this mod?

The least intuitively named mod ever.
