Nightmare POV:

I slowly walked through the doors to the castle I'd taken over. It was, okay, I guess. It felt very lonely. I slowly walked over to the kitchen. I didn't have much there, mostly just a coffee maker and some food. I decided to have some coffee. I wasn't tired or anything, but a little extra boost never hurt anyone. It was quiet. Nothing but the sound of my breathing and the whir of the coffee machine. It had been over 400 years since I turned my 'brother' to stone. Everything felt quiet since then. No incredibly positive aura near me. I sighed. I had more negativity than I needed right now. Yet I still felt like it wasn't enough. I grabbed my coffee and began walking to the library. Books helped to pass the lonely time. It had become a routine. Wake up, spread negativity, work, spread more negativity, get coffee and/or read, work, sleep. Occasionally the Destroyer of Worlds, aka Error, would come. That made things feel less lonely for a bit. He never stayed though. I arrived in the library. The little ghost of the dead prince and guardian of negativity was there. I was now the king of negativity. He was the one I took my body from. He was farther down the room, looking at books. He stared at me, pointing at a book.

"You want me to read that one?" I asked, my voice echoing in the big empty library.

He nodded vigorously and pointed at the the book again. I sighed. Reading with him was the only way he wouldn't annoy me.

I walked down to him and grabbed the book off the shelf using one of my tentacles. It was a story about two brothers. 'Of course.' I looked up at him. He tilted his head. 'Always with the family stories.' I thought.

After I read with him for a few hours, I left. He stayed in the library. He couldn't speak, or he never wanted to, so I just always assumed he felt comfortable there. He only annoyed me if I ignored him.

I walked through the deadly quiet halls to my room. I had chosen a small room with a bathroom. There were bigger rooms, but I didn't feel right in them. My room was decorated to my style. It was the only part of the castle that didn't feel eerily quiet or sad and empty. I sat on my bed and pulled out my phone. Maybe a movie could help pass the time.

~The Next Day~

I woke up at the time I normally did. Nothing seemed out of the ordinary. I quickly checked if anyone entered the castle while I was out. Nope, no positivity or negativity emotions in the castle. Empty...As usual. I sighed and continued my normal routine. As I was drinking my morning coffee, I got really angry suddenly and slammed the coffee mug on the table, shattering it. I needed a change. Something that made me have to do things differently, but what? What could I do to change something? Something dawned on me. I needed company. Someone in the castle with me. Someone who wasn't a angry dead prince.
