Why destroy when you hate it?

Chapter 11

I exit my room and go into my nest. Cross has put his chocolate in the library. He hides his chocolate in different places around the mansion that you wouldn't expect because Horror and Dust love stealing his chocolate. I grab a bar of chocolate with my strings and make my way to the living room, ears lazily twitching due to my mood. I found out if I use enough magic I can hear out of them aside from my normal hearing so now I have double the hearing capabilities.
Cross sees Error eating a bar of chocolate in his nest above the living room. "You made sure to put the hiding spot back exactly as it was?" He asks.
"YeAh." I lazily reply, tail swishing behind me. I decided I wasn't gonna wait and used more of the galaxy yarn to make a tail that also reacts to my magic. And somehow I can feel pain from it to so that's something new. I only feel pain if it gets shut in a door or gets pulled.
Nightmare notices Error is in the nest above the living room but says nothing and returns to his book. He know Error will leave his nest and join the gang when he's ready. He remembers when he first met the Forced God of Destruction.
(Flashback)
Nightmare had just entered the Anti Void to get away from the gang when he heard a glitchy cry of pain. Could this be the Destroyer of Worlds? But why would he be crying out in pain? He's immortal and practically invulnerable. He teleported
to the negative emotion source and was surprised at what he saw. There lay Error, the Forced God of Destruction, whimpering in pain.
Blood flowed from his wounds as his magic attempted to heal him. Several bones were broken or fractured. Most of his ribs were completely broke off. Dust cascaded down his form but he didn't die, he couldn't die. No matter how many times he tried Fate just wouldn't allow it.
Nightmare instantly picked up Error using a tentacle. He gave a small wince when he felt a bone shoot through the tentacle holding Error. He must have haphephobia. The King of Negativity thought as he sent a wave of negativity through his tentacle. He felt the Destroyer calm down and fall asleep.
(End Flashback)
Unbeknownst to Nightmare he is releasing a wave of calming negativity throughout the room.
I watch as everyone else, including Nightmare, fall asleep due to the calming negativity that fills the room. I start feeling tired so I close my eyes and succumb to the darkness.
