The Legend of Zelda: The Sage of Darkness

Prologue
The film starts with the telling of the legend of the Cycle of Eternity, with the Skull Kid (SoD) narrating. It shows Ganon (SoD) assasinating the King of Hyrule with his sword and killing the Royal Guards as well. He spots a maiden who has witnessed the murder, but lets her go out of arrogance. He then raises his arms, the Triforce appearing above him. The Skull Kid then declares:

"In a world of darkness and fear, a hero would arise."

It is then that Zelda (SoD) arrives, accompanied by the Hero of Time and six Sages. The Hero duels Ganon and strikes him down, allowing the Sages to seal him away to the Sacred Realm. The narration ends with a Sage laying a book down on a altar and the Skull Kid declaring:

"This ancient harmony between the dark one, the princess, and the Hero of Time, was a Cycle, repeating century after century at the edge of a knife. But what would happen if someone... evened the scales.  As they say, those who do not learn from history, are doomed to repeat it."

The scene then cuts to a hallway where two Hyrulean guards stand. Two figures then come out of a door, the Skull Kid, and Prince Ertegun of Gerudo Valley. As they pass by, Zelda, the descendant of the Zelda shown in the prologue, comfronts Ertegun about the treaty the Gerudo Prince has given her father, the king (which is designed to give Ertegun the entire kingdom). Zelda suspects that Ertegun has bewitched the King and his royal council, which is the only reason they signed the treaty. Ertegun however, fecicously claims that they signed it of their own accord and he only came forth with the treaty so that Gerudo Valley and Hyrule could ally to create a stronger military force. Zelda, aware that Ertegun is a descendant of Ganon, is well aware of Ertegun's lust for power. Seeing through Ertegun's facade, she reminds him of the Hero of Time, and that he was not invincible.
