King Sombra's Resurrection

Princess Celestia was pacing around the room, thinking, and planning how to get out of her cell. Her thoughts were interrupted by the sound of the guard. He was nicer than the rest and he loathed the king and how he ruled over this unknown land. The guard walked, over to her setting down a tray of food. As he did so, one of the many keys fell to the stone covered floor next to the tray of food. Outside the door the other guard heard the sound of the key hitting the floor, and asked “Everything ok in there?” The kind guard with Celestia said, “Everything’s fine”. His horn glowed, creating a copy of the key that fell. He walked towards the door and left. She picked up the key, a picked up a sheet of moss, and a stone brick that was loose, and set it beside her quietly, Princess Celestia put the key down in the gap and then covered it with the sheet of moss, then placed the brick on top of the moss, hoping it cushioned the key from breaking. She smiled as she looked at the stone covered floor. The moss covered small cracks and the rest of the floor looked the same. The moss fit perfectly with the room. She ate the food on the tray, then shoved the empty tray to the door. The door opened and the guard picked up the tray, closing the door and walked off.
She smiled and noticed a green dragon sleeping beside an egg, in the next cell. She whispered to the dragon “I need your help”. The dragon yawned and said to her, “I will help you but you have to do something for me. See this egg?” The princess nodded, the dragon continued, saying, “When you escape take this egg with you. Can you do that for me?” The princess said to the dragon “I will”. Princess Celestia used what little magic she had left to make a parchment and quill. She wrote furiously and rolled the parchment as the quill faded away. She said to the dragon, “Ok this is where I need your help. Send it to my friend’s place. She will know what to do”. The dragon looked at the address on the parchment, rolled it up and breathed green fire. The green fire consumed the scroll and within seconds it was gone.
