Shadow faded from the world of forms and things, falling slowly into the realm of the shadows, and the things that are meant to be seen with closed eyes.
It had once been home, not it felt like a constricting flow of things bumping against him. But he needed to be there. Now that link had shielded himself to protect what little was left of himself, the energy Shadow had for surviving was severely limited.
He dug on Link's memories, tracing back his steps as best he could. But it was all coming from too far away, and pieces of the memories were missing, leaving dense mists that stopped Shadow from fully understanding what had happened.
But he only needed one piece. The first time he had sung for Link. When the hero laid cold and alone, in the middle of a forest where he wanted to be lost into.
"Cry…" he'd whispered to him, making him scream in despair of feeling himself impure.
"Be gone, you monster!" shouted Link, running, trying to get away from something hiding in his chest.
"Cry, cry now…shout the truth, for only I will hear you, and I have heard it from the start"
Back then he was nothing more than a spectre putting together as much energy he could steal from his host. To bring back the memories, the knowledge, the power lost in that last battle where the hero had ripped him away from his heart.
"What are you trying to do?! Why do you still follow me?!" shouted Link. He looked back at the fading for of Shadow behind him and tripped over a rock, falling down on his face. Shadow laughed, loud and clear, pushing the hero over the edge of shame, of failure.
"I will be with you always." Not a warning, or a treat, but a promise.
"I don't want you to be with me. I want…I want…"
"But you have left Desire behind, little hero…"
And so had he. In Link's divine separation, Shadow had left his own desires, in the form of a small shadow drifting aimlessly through creation. He wondered what he should do then. Soon, the hero's party would be out of the forest, and he had to get his own part of himself back before anything could happen.
Luckily he still had Need, and that had kept them both together. Even if they couldn't touch each other, even if they couldn't want each other…The need between themselves, the need for one to be black so the other could be white. It kept them together.
