Zzynx, the Other (Part 2, the other Darkin)

So the part 1 got 50 views, so here you go:

Lore: There is only one Darkin known to man. He is one of five remaining, and his name is Aatrox. A tale states that he once led the Protectorates into battle, completely turning around the fight, taking the overconfident Magelords by surprise. Aatrox led that attack, and he annihilated all of the Magelords.

    But he did not. He wanted the battle to continue. He spared some of the Magelords, hoping someday the would grant revenge on him for killing all of the Magelords. It is unknown who these Magelords are, but they might be alive now. They seek revenge on Aatrox for his deed. 

     One day, they emerged from hiding, never revealing their identities. They sought after Aatrox. They pursued him endlessly. Then one day, as they wandered the ruins the battle, Aatrox appeared. The Magelords prepared for their fight. They all charged at Aatrox, who took flight towards them. Before hitting each other, a figure smashed into the ground, knocking them all back.

     "Who are you? You are obviously one of the other four. Wait . . . . . " - ??????
      " Yes, brother. I am here." 
      " So, now the final piece of the puzzle is revealed."
       " Yes. The puzzle is to your demise, brother."

    They grinned at each other and engaged in a brutal and gruesome battle. Blood flew everywhere. The Magelords could only watch. They watched as the brothers' blades drank off of each others' blood. Dust flew everywhere. When the dust cleared, this new hero of the Magelords stood over a kneeling Aatrox, whose blade was stabbed into the ground. The new hero laughed triumphantly as Aatrox quickly lunged upward, his thirst for blood into his well fueling him. This new hero evaded the attack.

       " I know your tricks, brother."

     Aatrox dove back down, slicing his blade into the hero, whose limb flew off. Aatrox took advantage of this, executing a series of fatal blows. The hero fell to the ground. The hero struggled back up, bleeding heavily, all the blood flowing into Aatrox's sword. He lunged for Aatrox. Aatrox willingly let the blade stab him in the heart. Aatrox stabbed the hero in the heart. Their blood flowed into the other's sword, and they both took their dark flight.

     Blood trickled down as they rapidly gained altitude. Then suddenly, the pools of blood on the ground soon formed Aatrox and the hero, still both of them with their blades in each other's hearts. They ripped out their blades in unison and backed away from each other. 

       " Our battle was a great work of art, Zzynx."
       " Indeed, brother. Shall the painting be completed another time."

      As the two Darkin flew in opposite directions, those words echoed across the battlefield.
