Moonpath to Elsweyr
Now that you've dressed up your Skyrim install, why not add more content? Moonpath to Elsweyr lets you head to the Khajiit homeland, but there's way more to it than that. You'll find new enemies, new quests, all sort of new enemies, and even an airship. Add in the new voice acting and you've got a mod that will keep you busy for quite some time.
