So, the other day I did the quest where you are sent on a treasure hunt for an old tomb for a Nordic Lord's bastard son that was made in the Skyrim Conquests in the 1st Era. While I have done the quest before, I noticed something odd about the armor he wore. He was burried with an Imperial Dragonscale Cuirass, Helmet and Shield, but nothing suggests that people have entered the tomb since it was sealed(the fact that several very valuable things are still there, inclusing Ebony braces and enchanted weapons).

So here is my question: Considering that dragonscales would logically be more common the closer to the Dragon Wars one is in time, and that Imperial Dragonscale armor was found in a (pressumably) sealed tomb from the Skyrim Conquests, is it possible that the rather rare Imperial Dragonscale armor is really armor left over from the Skyrim Conquests that has been adapted into the Legion?
