The Dragon Blade (Skyrim 11th Anniversary).

This mod adds a completely new sword to the game. Dragon Blade. The sword itself can be found in High Hrothgar in the meeting room. There are 3 available in the room in one-handed and two-handed versions. There are 2 one-handed versions for those who prefer dual wielding. Both one-handed and two-handed weapons rank slightly higher than Daedric weapons in statistics. There is also an enchanted version, but it will appear in a unique location in a future update. In the meantime, you can give it to yourself along with your console if you want.
