The Legend of Zelda: The Triforce of the Goddesses
Prologue
In the beginning of time, when the black universe was without stars and Hyrule simply wasn't here, only the three goddesses existed. These beings were the perfect divine; nothing like the beings of Hyrule that they would soon create. So then, in the beginning of time, the three goddesses ascended from the heavens to shape the land of Hyrule.
Din, with her strong and powerful magic, created the land that their people would inhabit. She raised mountains out of the very core of her earth, and indented the land in other places to make for a vast and intricate scenery.
Nayru, with her Wisdom and magic, created the laws of the land. She filled the rolling hills with green grass; the deep crevices in the earth with shimmering blue water that swirled with foam; the space above the ground with thick air; the vast forests and forbidding deserts. She created the laws of physics; gravity, precipitation, temperature.
Farore, with her great courage, created the denizens of the land who would uphold these laws. She created a vast variety of animals and scattered them across Hyrule. She then created the intelligent beings who would each control a part of Hyrule; The Zora's would take the Waterfall Domain; the Kokiri would take the Forest; the Gorons would take Death Mountain; The Gerudo would take the Desert; and the Hylians would be gifted everywhere else. However, the Hylians became greedy, and claimed more than was rightfully theirs for themselves... this saddened the rest of the species, but they couldn't do anything about it when the Hylians advanced even into Hyrule Field: The place meant for them all to share.
When the three Goddesses departed from the land they had created, they left behind a relic. This relic was called the Triforce, and it had three sections; each one represented one of the three goddesses that created the land of Hyrule. That omnipotent power lay undisturbed for a long time...
...Until Ganondorf entered the Sacred Realm. He tricked a young Hylian from the forest wearing Kokiri Garments into giving him the 4 keys to opening the Door of Time; the gate to the Sacred Realm. He entered the Sacred Realm and took the Triforce for himself. With his evil heart, the land of Hyrule was thrust into chaos, and misery reigned for the next 7 years. People prayed for a hero; they never lost hope. And after 7 years, their wish came true.
The boy who had been tricked by Ganondorf 7 years prior had returned. He and his fairy, Navi, roamed the land freeing the 7 sages. Once they had, the sages created a bridge into the horrible castle that belonged to Ganondorf. There, The Hero faced off against Ganondorf. In a long battle, he finally defeated Ganondorf with the blade of the legendary Master Sword; the sword of evil's bane.
The power of the Master Sword held down Ganondorf while the 7 sages sealed him in the Sacred Realm. The doors to the sacred realm closed, and Ganondorf was sealed there. The sages hoped that seal would never be broken.
What the sages and The Hero didn't know was that the Door of Time wasn't actually a door; it was a portal. The portal led to another world. The world in the sky, the Sacred Realm. The Sacred Realm was vast and endless, and the Chamber of the Sages wasn't even one trillionth the size of the Sacred Realm. The Hero and the sages didn't know that this realm was accessible in another way. However, years later, it was discovered by a powerful wizard that there was another way into this Sacred Realm. And - presumably - another way out.
