ATLA: The Master

What would happen if a chance was given to a man? A chance to rewrite history that he once thought to be fiction, and change both himself and the world. For the better or worse, follow Kypher as he survives in a world he was destined for... I'll try to update once a day. No harem, always hated them. Ps. I do not own any of the characters except of my original ones.
