A Gnisis Trader Shulki Ashunbabi was one of the first NPCs created during the development of Morrowind. You can see him on concept art, mockup screenshots, actual in-dev game screenshots even, and in all these he's, well, a guy. Yet, for some reason, in the final version of the game Bethesda made him into a lady.

This mod makes Shulki a man again, gives him cool pauldrons he's seen wearing in a mockup screenshot and implements a unique greeting from the same source.
