Az had been training in the outdoor training arena for a few days, taking time to recover for a blood sport encounter with an oversized orc. That didn't end well, but he managed to kill it, but not without a price to pay. He had massive cuts on his back, chest, and shoulder. Thankfully, he stopped in the woods and got help from a new acquaintance. She helped him with his wounds, and helped him get back on his feet. It was a nice encounter, and well worth it.
So, training with a fairly large man, big enough to pass as a blacksmith, he felt anger rise within his demon side. It wasn't normal, as he didn't get angry with these fun fights. But he kept fighting. His wounds still hurt, not quite healed completely yet, making thigns harder for him. He wasn't as flexible, and couldn't put enough power into his blows. But he knew the big guy he was sparring was going easy. Az asked him too.
Az was keeping up though. They'd exchange blows, come back for more, and just keep the big circle going. But suddenly the big man started getting a little rough, obviously geting bored. He took the war hammer he was using to fight with and slammed it into Az's chest. Az flew back to the ground, the wind knocked out of him. And it set off his demon anger. He had caught his breath, but he wasn't moving. He felt something inside of his pulsing, burning in his heart. His anger rose, and his body went rigid. It went limp again, and Az had control again. He pulled himself up in to a kneeling position, feeling an intense pain in his back.
People started gathering, as they had seen Az train here frequently, and never saw him in pain like this. They kept their distance, and watched. They started mumbling about something bulging in his back, gasping in horror. He felt his back bulging too, but didn't know the cause.
Suddenly the bulges surged to two big bumps, one on each shoulder blade and lengthening down his back. He felt it squirm, like it was a snake writhing in his back. Then he felt it pop. His back ripped open at the shoulder blades, and big demonic wings sprouted out, blood splashing everywhere and blood dripping off of the wings. It hurt terribly for Az, and he was in too much pain to scream. The crowd gathered around screamed, seeing the 6 foot long wings sprouting out of his back suddenly.
Az knelt there a long time, waiting for the pain to subside and numb before trying to see what happened. He knew what happened, but he still had yet to see it. As he knelt there, his mind began searching for a reason why he had these demonic wings. He knew his mom was a high demon, and figured she must have had wings and passed them down to him. He should be glad, but he hurt too much and he hated his mom.
the pain finally settling down to a dull roar, he looked forward and smirked at the people looking at him in front of him. He stood up, feeling pretty off balance with the added weight. The wings were outstretched behind him, and Az had to lean forward slightly to keep on his feet. Then he decided to try and test them. He moved them forward, hearing them brush through the air very quietly. He brought them so that they pointed forward. He looked at them, taking in every detail of his new physical feature.
They were a little over 6 feet long, jet black, and demonic. They looked perfect for Az, being half demon anyways.

((that's them))
Moving them back expertly as if he had them forever, he raised them up fully and looked up. It was almost a second nature to him all of a sudden being able to move these wings. They soared up, extending his hieght to 12 feet, and splashed the remaining blood off. He flexed them up for a second, and brought them down fast. They pushed air away fast, and a burst of wind kicked out in all directions, also kicking up dust. He felt himself get lighter suddenly, being lifted off the ground slightly. And he didn't even thrust down as hard as he could. He grinned again, his adrenaline pumping so hard he didn't feel anymore pain.
Again, he flapped his wings up, and brought them down, this time harder. He felt himself rise up a couple inches and fall back down. People gasped once again, and some of them cheered. And a lot of them ran in fear. It made Az feel big suddenly...
This time giving it his full effort, he began flapping his new wings, blowing wind and dust everywhere, and lifting himself off the ground. He rose up a few feet, and flapped his wings hard enough to maintain the height. He did feel kind of odd suddenly knowing how to fly, but it also felt good. He turned to the side, facing the direction of Lomedor. He leaned forward and flapped harder, and lfew in that direction a ways before stopping. He darted through 200 ft very fast, and was glad for the speed of his flight. He knew now that he would be able to fly somewhere fast, and knew it would be a great advantage to have in a fight.
He flew back to the crowd, and saw that crowd had gathered to watch him fly away in awe. He flew back and landed, stumbling a little bit but managing a good land. He stopped in front of the crowd, and grinned at them. "Alright, who's up to fight?" He asked them. One stepped forward and motioned for Az to attack.
Having apparently a second wind, Az went for him. He ducked low and forward, and flapped his huge wings back. He propelled foward, surging at an incredible speed. Getting close to his opponent and the crowd scattering to get out of the way, he brought up his feet and kicked the man in the chest. the man couldnt' react in time, and was sent flying backwards. Az used the recoil of his blow to throw himself into a backflip, and landed the flip easily using his wings to keep balance.
He was a natural, and so loved them. The crowd cheered in amazement, and Az nodded to them. Wanting to go fly now that he had a slight hang of it, he put up his wings and surged them down, and flew up into the air at a breakneck speed. In that one flap he got himself up to 50 feet high, and flapped again to get higher. He soared up to the clouds, and enclosed his wings around him. He flipped himself over and fell into a dive bomb, and fell quick. He kept himself in that position as he fell, and opened his wingspan once he was a few hundred feet above the ground. Doing so put him into a high speed charged straight again, soaring at an increible speed acrosst he landscape.
He flew aimlessly, just getting the hang of flying for now. He would fly in one direction and suddenly flip over and start going the other way, then suddenly surge upward, and so on.
Thanks mom, for giving me the ability to fly. He thought, thanking him mom silently. That was the only thing she did for him. Ever. And he wanted to get back at her for it. So he flew on, soaring back towards the training arena.
He reached it faster than anything other mode of transportation other than teleporting, and landed at a running stop. He stopped, and stood in front of an awed crowd of fighters. Kneeling back down, he found that he could retract his wings too at anytime, and did so. Doing so also sealed up his wounds, and leaving a scarred slit for re-exiting. They disappeared too without so much a bump on his shoulder blades, except for the scars. Doing that also readjusted his balance, and adapted quickly.
Making sure he could get them out again, and forced them back out, and felt them slide out of the slits on his back. They came out harmlessly them time with no blood or pain. Chuckling to himself, and retracted the once more, and walked away, completely satisfied.
