The Triforce

The triforce is the essence of the 3 goddesses. When the 3 goddesses created hyrule they left a object made of 3 triangles called the triforce. The triforce was left under the protection of the goddesses Hylia. Since Hylia was a goddess herself she was unable to use the power of the triforce. The 3 pieces of the triforce were the Triforce of Wisdom, Power, and Courage. The triforce of Wisdom was formed from the essence of Nayur. The triforce of Power was formed from the essence of Din. The triforce of courage was fromed from the essence of Farore.If someone was able to claim all 3 pieces of triforce then they would gain the true force. If anyone had the true force then they would decide the faith of hyrule. The only way for someone to gain the true force they would need to be perfectaly balanced in wisdom, courage, and power. If someone touched the triforce and was not perfectly balanced then they would gain the piece in which they were most balanced with and the other to pieces would choose thoes who were most worthy.

Link is chosen hero of the goddess and has the triforce of courage. Ganon hold the triforce of power. Ganon is also know as Ganondorf. These 3 gained their pieces of the triforce because Ganon had used Link to enter the sacred realm and had touched the triforce which split it into 3 pieces.

Power was his greatest strength so he was given the triforce of power. This gave Link the triforce of courage and Zelda the triforce of wisdom. Since Link has the triforce of courage he has the ability to master any weapon he holds without training. The triforce of power gives Ganon his great strength and infinate mystical power.
