Great Cataclysm

The Great Cataclysm was the moment where Ganondorf, the Gerudo thief king, laid his tainted hands on the Triforce for the first time after finding the entrance to the Sacred Realm and transformed the Realm into the Dark World. The Dark World reflected Ganondorf's heart, and turned into a world of darkness and despair. Based on Ganondorf's inner self, he was transformed into Ganon, the King of Evil and Prince of Darkness.
