This is the Realm of Reflections. Take a seat humans of Earth, for this is a realm unlike your own. A place devoid of peace and lacking unity; a place of excess war.

Once the land was populated by humans such as yourself. They hunted the forests, killing all who could not defend. They built a civilization in the realm. But a spirit fox had found them. The fox was fair and white like an angry blizzard. Seeing their ignorance of the land, she blessed them. She changed their souls to match her own. This was the birth of the Sprites.

A sprite has two forms; its human form, and its spirit animal form. Its human form resembles that of a human or its previous form. But this form is made completely of spirit and energy, made by their soul. Sprites generally use this form as it requires little energy and it is often more comfortable; especially for previous humans. The spirit animal form is basically the form of their spirit animal. This form is powerful and drains the soul of energy. Only strong souls with plentiful energy can continuously keep this form. Sprites can only die when their soul is shattered, and there are rarely exceptions.

Once the sprites rose from the crumbling towns, they built a strong civilization; a civilization built by magic and unity. No one knew when or why, but a second species had rose that rivaled the sprite's strength. The Demonons. This name was given because of the rumors that they were the children of demons.
Demonons come in a variety of shapes, forms, and species. Whether it's humanoid, or the form of an animal, or something that is indescribable. A demonon will die if their body is destroyed beyond repair, but there are also exceptions.

Souls are always in the shape of an orb, filled with energy, and glass-like. A sprite has a soul of light. Their soul glows passionately, and will shatter if broken. A demonon has a soul devoid of light. It will melt into black goo if broken.

Despite the lack of activity or violence in the community of the demonons, the sprites attacked the demonons out of fear. The demonons did not take this lightly and attacked twice as hard, more vicious than the sprites. The sprites retaliated with demonon hunters, a type of hunter with the sole purpose of killing demonons. The demonons also retaliated with sprite assassins, assassins with the purpose of shattering a sprite's soul.

The war raged on and on for centuries. It raged on when are ancestors fell in battle. It raged on when we were born into this world of combat. Sprites hated demonons. Demonons hated sprites.

Why was it different? Why was it different for him. What could have possibly persuaded him to side with the demonons?

Why was it different for the black fox?
