Aftermath of the first Dalki war
A long time ago, during the first Dalki war, disaster had struck, changing Zero's life forever. Living peacefully at the top of the temple, Zero had continued the traditions of his family.
Teaching all those that came to him the power of Qi. This was where one of his students had been abandoned by his parents. Leo had been abandoned, and just like with all his pupils, Zero had brought him into part of his family adopting him, and he too had taught him Qi.
Looking back, he was unaware that this would be the turning point in his peaceful life. With the Dalki war starting, Zero wished to remain hidden in the mountains away from it all.
However, a mistake, a grave mistake from one of his dearest students had changed everything, showing the world his powers, and allowing for the world to discover them.
