Shadow found eternal night was quite enjoyable. He loved the beautiful moon. Was Luna happy now? He hoped so. He hated to see her unhappy. But he also wondered why ponies didn't feel the same way as him. So what if the sun wouldn't come up? There was enough light to go around even without the sun. He decided to go visit Luna. He flew to her cloud. "Luna? Er... Nightmare moon?" "Oh Shadow. Have the ponies not learned their lesson yet? You're the only good pony besides me. Look at all those pathetic ponies whining. It's getting on my last nerve." Her horn started glowing and the noise silenced. "That's MUCH better. Now Shadow, I have a plan. Celestia doesn't understand me. She is a horrible ruler, and I think we should take over the throne. Together." Prince Shadow... Yes I could use a name like that. He thought, and smiled. "I'm in." "Good. Now here's my plan. I am very good with a sleeping spell, and I have been saving my energy for a very powerful one. It will put all the ponies in Equestria to sleep, that is, except you, I, and Celestia. Why Celestia? Well we would want a fair fight, wouldn't we?" She doesn't really mean... Does she? Kill the Princess? Her own sister? That couldn't be right... could it? "We're going to... KILL Princess Celestia?" Shadow asked cautiously. "Bingo. Now come, we can't waste time." She flew down to earth and declared: "Hello, my subjects. Sleepy?" Her horn glowed and everypony collapsed, asleep. Nightmare moon smiled. "Come Shadow, We have a princess to finish."
When they got to the castle, Celestia was trying to rouse her guards, but with no success. When she saw Nightmare moon and Shadow, her eyes narrowed. "Luna... You did this?" Nightmare moon laughed. "Yes, Professor! " She snickered. "And now I'll finish YOU." "Luna, I didn't want to do this, but you've forced me to. You have to think about what you've done, and I know the perfect place for you to do that... The moon. Goodbye, sister." Her horn started glowing. Her crown was different than it was before. Shadow didn't know it at the time, but that was the elements of harmony. "Celestia, No! NO! NOOOOO!"Nightmare moon's screams disappeared into the night as she disappeared. At first Shadow was too shocked to speak, then he ran as fast as his hooves could carry him. Celestia just watched and sighed. "Maybe he will learn eventually." She muttered, and went over to her guards, and watched them wake. As soon as Shadow was a fair distance away from the castle he watched miserably as the sun came up. He watched the moon go down, and noticed a mare-like figure there. That's my Luna... He thought miserably. Suddenly rage pounded inside of him and he knew what he must do.
Get revenge.
