Prologue
"Long ago, people lived in peace, bathed in the warmth of light. Everyone loved the light. Then people began to fight over it. They wanted to keep it for themselves. And darkness was born in their hearts. The darkness spread, swallowing the light and many people's hearts. It covered everything, and the World disappeared. But small fragments of light survived... in the hearts of children. With these fragments of light, children rebuilt the lost World. It's the World we live in now."
What shape appears in your Heart?
Let's start your story.
A black-haired person wearing a black and red jacket opening their eyes in surprise. They were on a platform that sported a heart design. Around the heart was six animal heads. A Unicorn, a snake, a bear, a fox, a leopard, and a goat. Wondering where they were, they heard a loud, booming, echoing voice speak.
What appearance takes the heart that guides you?
The person walked over to the leopard face, representing the Union, Leopardus.
Dark shadows began moving from the edges of the platform to the person as they reacted with a surprised look on their face. The shadows cover the platform and form an orb of darkness around the person to swallow them. Suddenly, a light shines within the orb of darkness. The person is revealed to be holding a key-shaped object. The darkness has completely vanished for now.
Keyblade... The power of Light that drives away Darkness.
Light suddenly comes forth from the keyblade, bathing the person in light.
