Quick note about Rhaast being a weapon
Before we all get gungho about our theories and crafting. I just want to point this out. I don't think all darkins are weapons... only that rhaast is unique in some regards.

at 9:07 , Xayn implies that rhaast was captured and sealed inside of a weapon. When rhaast is chosen, he even has a line saying "I am finally free"
I know people think virus's bow is a weapon as well, but so far, we only have one confirmed darkin weapon, that is rhaast. I wouldn't put money on aatrox being a weapon himself ( seems like lazy writing to me ), but who knows.
Edit: Further reason why I belive that rhaast didn't start off as a weapon https://youtu.be/UcW8Rl_0nBE?t=2m37s
When he says "ooh thse legs will take some getting use too" it can be taken, as a sign that he never had them before, or that he had different legs before, and these are way smaller than his original ones.
