Riku thought back to when he and Mickey had closed the door to darkness. It was the first time in a long time that Riku was able to see Sora as himself and not in someone else's body or with his thoughts being invaded. It was ironic really that once he had found the light he was missing, Riku ended up locking himself in the realm of darkness. But he knew he had done it for Sora and with the king's guidance he wasn't worried.
"When we closed the door I felt empty inside, like how it was on the island that day. You were so close, but I knew that in order to truly be with you again I had to confront the darkness within me, so I had to let you go again. I ended up in Castle Oblivion somehow, down in the basement. I was looking for Namine there, and I journeyed upwards, eventually running into DiZ. He basically guided me on my journey and when I found Namine, I figured out that she was restoring your memories. I was so emotionally unstable Sora, you have no idea. I didn't know how to deal with the contrast of light and dark within me and I didn't think I would ever be able to handle it if you forgot me. Vexen created a replica of me in order to break you, but I eventually ran into him and defeated him. The whole experience was a blur really. I just wanted to find you so bad, and no matter how many staircases I climbed, you weren't there."
Riku frowned, the memories now fresh in his mind. It was painful to have to reminisce. He had no idea what made him think the way he had back then but it seemed to him that things weren't changing in his brain. He was still as frazzled emotionally as ever and being in this strange place was making things worse.
