yes could very well be a redguard Legendary, yet I am also juggling with the idea of it being the Dunmer.
after a bit of research. it appear that I can name it Subotai, as it was actually the name of a general of Genghis Khan. Not only Conan friend in the movie.
Contrary to the Atlantean and Master swords, this one is much less known and will fit in Oblivion without having a big Lore issue because it's a movie prop. most people will never get where it come from as the weapon has very few screentime, and is mostly never shown fully.
Here's is a picture of Gerry Lopez in his Subotai gears with the sword. it will be approximately the size of the Curved Dagger in Redguard. or just a little bit bigger.
and the final colors..for the blade.
