From the void, God had called forth light from darkness, and the universe had known brightness.
From that brightness, God created day and night. He put the sun to light the day, and put the moon and stars in the blank ink of night.
Then God divided Heaven and Earth, and from the Earth he separated the land and the ocean. In these different surfaces, He planted trees, grass, and flowers of all colors. He then breath Life in them: the fishes, mollusks, and crustaceans making their home in the deep sea, the mammals roam the dry lands, and the birds find a place to roam in the skies.
Lastly, he moulded a form close to his own, breathed them life and called them Man. And God loved this creation.
And life in this paradise was bliss.
But Lucifer, one of the high archangels of the Heaven's court, had grown jealous of God's creation. He had deceived them and pushed them to sins, and along with many angels, had staged a coup against the Maker Himself, sending the entire Heavens into war.
For a hundred days, the angels fought against their rebelling brothers and sisters, splitting the skies and trembling the lands. The tides turned as Gabriel, a fellow archangel, destroyed Lucifer at the expense of his own life. But being angels, their souls survived total destruction and had fallen into the earth.
With the death of their leader, the rebelling angels escaped from the Heavens and to Earth, where they had taken off their pure white wings and turned themselves into demons.
Millenniums had passed, and the demons continued to live in the darkness, trying to destroy all of God's creation.
But Man had also learned how to fight. Blessed by the angels, their guardians and protectors, they had learned to wield holy weapons that can destroy the fallen demons and protect humanity from their threats.
