This Skyrim mod infused the sword Dawnbreaker with runes of the Dragon Language. While technically the runes should be in Daedric, it's kind of cool to think about the Player (the Dragonborn) holding the sword, and like The One Ring it emblazens with a magical script when held by the right person...
The runes on it are "Tuz Do Fin Shul" which translates into Blade of the Sun, I felt it was kinda fitting due to the swords properties
