"Come to me, Zenithar, for without you, like a child, I might fiddle and fret when only through struggle and labor may I craft a work worthy of your name and the name of my patron."
My first thought was that that had to be made with the CK, because there isn't that much gold ore nor that many gold ingots available in all of Skyrim. Then I remembered there probably is that much iron that can be transmuted. No matter how it was accomplished, it clearly took a great deal of time and effort. By the end of the video I was laughing due to the sheer awesomeness.
I both applaud your resolve and fear for your sanity
