I am not evil, whatever those two may think. Even after I've plunged the realm into Twilight, hurt the Twili people, and possessed the princess of Hyrule, I'm not evil. Even as I cross blades with the poor, too thin, and probably malnourished teenage boy chosen by Farore, I'm not evil, and it's nothing personal. It's just business.
I've been in this game of chess for years, helping balance the world. I don't enjoy the evil I do, but I must. Evil must rise before good can come. The night must come before the dawn, the winter before the spring. It's all about balance, and I am the ultimate peace keeper. I'm not a god, but I was chosen by Din. It's my destiny to go through every life, keeping the balance by committing acts of unbelievable cruelty—all so Farore's champion can fight me.
I suppose Zelda is important in keeping the balance, too, but ultimately, it always comes down to Din and Farore. Perhaps, Nayru is wise enough to keep her Chosen from the battle. I know everything, of course. I must be evil to keep the balance, and I know that whenever I come, it signals the balance falling. I must commit horrendous deeds to restore it. That's just the way it is. I must restore the balance, and I must face Farore's chosen, even if I have to forcibly drag him into my war.
That's why the Bulbins kidnapped his friends. When I came to this life, I realized that this Link, the Link of Ordon, had no reason to fight. He had no fire, courage aplenty, but no motivation. So I gave him some.
As I face him now, I pity him. He thinks Midna is still dead, and even though I've become accustomed to hurting the hero for the sake of the world, I'll admit it's cruel. We cross blades, and I shove back, knocking him to the ground. My work is worth nothing if he doesn't work for my defeat. He rolls to the side and stands again. For a moment, I wonder how in Hyrule he manages to keep that hat from falling off his head. In the next moment, he lunges at me, and we cross blades again.
When we do, there's an odd look on his face. It's almost confused, and I think I know why. I've suspected for a while. Link and Zelda don't remember their past lives as I do, but sometimes, when Link and I fight, I know he feels something familiar. Something distant and insubstantial tugs at him when Power meets Courage. It would explain some things. I have noticed that he's become rather apathetic over the years; he takes more risks. He'll jump off bridges without a second thought, jump from cliffs and buildings as if he thinks himself invincible. It's as if he just wants it all to be over. It's as if he's just so tired of fighting, and he probably is. I am.
But we keep going anyway. Our blades clash together, sending sparks flying into the air around us.
Zelda places great faith in the forces of Courage and Wisdom, but I don't think she's every stopped to consider the unbreakable bond between Courage and Power.
