As Nightmare Moon awoke she has remembered one of the doors in the hall. The more she seemed to think of it, she would remember more details. That door was fairly large, adorned in what seemed to be black stone, with a pattern on it that resembled that of a dark cave. The door itself seemed to be made of shadows and was pitch black. Something about that door was unlike the other doors there. It was not normal, it also felt rather sinister too. Unlike the other doors, there were black shadows that seemed to emit from under the frame even into where the doorways were. Whatever the case, whoever's door that was was not an ordinary pony. For a while, this probably captivated Nightmare Moon's mind.
Nightmare Moon awoke to a rather quiet atmosphere. The construction noises outside were still there but it wasn't as frequent as it was last night. Outside Nightmare Moon's room the guards stood. They wouldn't dare wake her or bother her. No doubt Nightmare Moon would have spent a bit in her room to get ready for what would come tonight. When the guards would see Nightmare Moon they stand up straight and salute her as if they were statues.
A unicorn would be putting up some tapestries. She was wearing some sort of clothes themed with dark blues and purples. Her cutie mark was 3 blue diamonds. The tapestries were all about Nightmare Moon standing proudly over the moon, with the landscape of the night was done in quite beautiful work. A few ponies were there, bowing before Nightmare Moon loyally. The Unicorn was focused on putting the tapestries up in an exact, perfect manner. There were other guards going about their business in the castle. Whenever guards or ponies would see Nightmare Moon, they would salute to her or bow down.
Twilight Sparkle was still asleep in her room. She had a nice sleep, it felt amazing to sleep in a bed for the first time in a long time. The guards outside of her room were standing there, as they were ordered to prevent her from leaving during the night.
