So, while I was designing a keyblade for a friend, I got to talking with another friend of mine, who when I came up with the idea for an Elder Scrolls keyblade couldn't see how I'd pull it off. So I LITERALLY made an Elder Scrolls keyblade: I used the titles of the five main Elder Scrolls game to come up with this, plus some extra bits.

Elder Scrolls Arena: The ribbon linking the charm to the keyblade, plus the crack patterns on the blade
Elder Scrolls II Daggerfall: The blade itself
Elder Scrolls III Morrowind: The charm is based on the flag from the front cover (which, incidentally, has two shapes very similar to the Oblivion pi symbol and the Skyrim dragon. Interesting)
Elder Scrolls IV Oblivion: The handguard and stone that holds the pieces together
Elder Scrolls V Skyrim: the head and teeth of the keyblade.
And the hilt itself is made of one of the actual elder scrolls.

Also, A) I am not a fan or player of the Elder Scrolls series, so I don't know the mythology or universe, B) I'm probably not going to finish this like my Harmonious Element key blade (you'll see it soon) due to how complex it is and beyond my skills, C) there is no C, and D) this was done in about forty-five minutes because I wanted to see if I could do it. There, that's out of the way! Thanks for looking! Oh, and I apologize for the bad name, I couldn't think of something. "Dragonborn" seemed inappropriate for this particular design.

And the first one who makes a "keyblade to the knee" joke will have to live with the fact that I said it here first. Nyeh. :p
