'A man is good when he is a whole. A man is evil when he has lost what makes him morally human.'
-Philisophical Proverb, Author.
Once, a king of the desert amazons ruled the world by the very genius of his wisdom and power. One would think that, if such a man could govern the world, he would be the very key to recovery from past darkness.
The king of the world was called Ganon. He was renowned for his amazing powers in magic, and his superb wisdom to battle wits. He vanished men with his magic, and he manipulated people with his great wisdom. Some had revered him as a god, while others had named him a demon.
Ganon had a terrible aspiration for power, and the very power he sought was that of the Heavens. When he ruled the world, many were told he was, in fact, of the Heavens itself. When he appeared before the people, he rose his left hand as if in a salute, and revealed a golden mark upon his fist to confirm his divinity. A Golden Triangle it was, and that was the power of the Heavens.
With this divine power he changed the world to his liking; and came to pass that Ganon never made decisions that were in the favor of his subordinate peoples. It was widely known that Ganon was merciless in his chase for power; death would line the pavement for his success if necessary. He destroyed nations or corrupted their officials, and had no mercy for anyone who could stand against him.
Ganon would often have to eliminate foreign leaders in secret, and he wanted the best in that killing art. And in the village of Kakariko, a strange and mysterious folk, known in tale only as the Sheikah, settled there. These people were the very inspiration for assassins, as these people could become the very shadow of their prey. And Ganon wanted that.
However, Ganon was too late to enlist their aid, for they already swore to the Royal Family of the land of Hyrule, and they were in allegiance to the Heavens. Ganon, in a fit of rage, condemned the village to be haunted by horrible creatures of the darkness that not even the Sheikah could cage. The Sheikah were completely wiped out, all but their leader, who was missing.
When marshalling forces against other nations, Ganon trusted the Gerudo, the very people he first ruled. But he needed weapons, and he could not win wars only with spears and catapults. He went to the Mountainmen, the Gorons, to build weapons of war and enlist powerful Goron warriors. Their leader, Darunia the Fiery, refused, on the grounds that he could never trust a man who betrayed a superior. Before Ganon was Ruler of the World, he was chief advisory to the King of Hyrule.
Just as he was angry at the Sheikah, he was twice to the Gorons. To punish them for refusing him, he imprisoned Darunia's people in the topmost mountain, and then he awoke an ancient demon that haunted the Gorons in the past. Ganon had learned to tame that demon, the Dragon Volgavia. Until Darunia accepted his offer, Ganon would continue to feed his people the horrid beast.
It was known to the people that he sought power, although he had divine power. They could not grasp why this man, whom they referred to as an angelic demon, would continue his path of destruction to find power when he had it. After all, he destroyed nations, predestined people as it were, and changed the world to his will.
It was only until after the world was freed by a boy named Link, also known as the Hero of Time, that its people discovered Ganon's mad reason to seek power. When Ganon claimed the Power of the Heavens, the Triforce, he took only a piece of it; the Force of Power. After this, Ganon discovered that, in order to be perfectly divine and powerful, he needed to have the other two pieces. And those pieces lay in the hands of the Hero of Time, Link, and Hyrule's Princess, Zelda.
The destruction of nations, and the damnation of his people, were factors of a search for two people. And to find even one of then, Zelda, he did horrible things. He damned the Sheikah, he imprisoned the Gorons, he let loose hell upon a children folk (the Kokiri), he choked the life out of a people of the water (the Zora), and he even enslaved his own people (the Gerudo).
All for what? To find two people? What madness drove Ganon to desire such power? I write this prose to take a deeper look into our favorite villain. It is fictional, of course, and represents my view on the matter. Honestly? This is my expression of the Zelda world. And here, I express myself by explaining Ganon and his reason for being evil.
