He has always been different from everyone else. Friends, family, strangers. It wasn't until he grew older that he realized that he was mad of darker things. It was apart of him or even stitched into his soul. No he was darkness himself. Darker than black and more deadly than the sin itself. And he loved it. Loved every bit of the chaos he caused. Be it for his pleasure or no reason at all. And as time went on he realized his purpose in this thing caused a life. He was the darkness to their light. The avatar. And he would make good on his sole purpose and nothing else. To destroy them. And as he took down one after another. Something kept bugging him. Noticing that he needed to eliminate the source to get rid of something all together. So he slipped through the cracks along with every life. Every redo. Looking for the perfect chance to end it all. And of course he came close but it was never close enough. His hatred grew at an alarming rate but who could blame him. She was proving a harder target then he once thought. So he enlisted help. With the power he stole from her soulmate. Vaatu was easy enough to tempt but he hadn't steal all his power like he intended to do because she stopped him again. But he had enough to change peoples lives. The ones he knew could handle being by his side. There were slip ups because each life was different but somehow the outcome was the same most of the time. The world was impossible at best and he had to admit he was surprised that she had held it together for so long. He would have given up already and took the power back and closed off the spirit world. However he knew this time was strangely different. He didn't knew who the odds were in favor of this time. Last time was more a of a tie. Something felt off and he had yet to figure it out. It nagged at him constantly that something was wrong. Missed placed. Out of order or forgotten. His skin burned with anger wanting to be released. That sent him into sleepless nights of wanting to rip something apart. Shred it to fucking pieces and that often lead to staring at Aang. Wishing he could act it out on him but he knew he couldn't. The soulmate part made sure of that.
