Syos, the world of demons

[I KNOW ITS PROBABLY NOT A GOOD DESCRIPTION AND VERY LONG BUT I HOPE YOU LIKE THE STORY ONCE YOU START READING]
It was the time when demons lived on the planet called Syos. The people there believed in the legend of two dragons that created the planet. The Dark dragon called Maria and the Light dragon called Arron. They had to unite for the peace and lived in the Center Country. They made the guards of 12 colors that had control over animals their personal guards. They fell in love and had two dragon babies. One was a boy, more on the Dark side shining like a beautiful black crystal and had powerful dark magic. The other one was a girl and had power over both dark and light magic. In her dragon form she shone like different diamonds. They lived a happy life in the Center country as lords of all land. They chose different demons as demon lords to protect the people of North, South, West and East Country. Over time the demons started killing people and Maria and Arron used a lot of power to bring peace and went into a deep sleep. Their son and daughter were running away from there to the south. They escaped promising to bring peace once again.

Over many years that went by they learned to further control their powers. The girl stayed in a village taking care of the people and the boy became one of the strongest demon lords known to man protecting the village in which his sister lived in pretending to be human.

Will they bring peace to the lands or will the evil demons win? Will they find their eternal love? Or will they live a lonely live for all times?
