Idea for Another Darkin Champion(Besides Aatrox)

So I recently read the Aatrox lore, and I just noticed that in the text it stated that there were five other remaining Darkin. So I got to thinking, what else could be a Darkin based champion? Then another small detail caught my attention, the full champion name of Aatrox is Aatrox the Darkin Blade. So what if there was another Darkin that had a weapon that was connected to them like Aatrox. I imagine this champion could be an ADC or support somewhat like Blitzcrank or Thresh. Then again riot can make this whatever they want and go further with this champion. Personally I would love to see another Darkin champ it could add a whole different side to the Protectorate and Magelord fight or maybe this could be a rivalry between Aatrox and this new champion. So what do you think.....?
