Revenge of Tenebris

The black stallion opened his eyes. "It is time." he said. A guard just happened to be passing by when he heard the stallion mumble to himself.

"Huh? What are you mumbling about in there?" he asked, "Have you finally gone crazy?" The stallion lifted his head, and his horn glowed. Suddenly two tendrils shot out, and rammed into him. "I-Impossible! You shouldn't be able to use magic!" he said. One of the tendrils started to suck the energy out of him, and the other grabbed the keys.

He unlocked the door just as he finished draining the guard of his magic power. "Well that's your mistake." he said, throwing the guard into the pits of Tartarus. As he started to walk along the path some of the prisoners noticed him.

"Hey get me outta here!" one called.

"Help us!" said another one. Finally he could stand no more, and sent out tendrils, and sucked up their magic power. After that no one called out again. He smirked, and continued along the path until he turned a corner, and ran into two guards. Their eyes widened in surprise.

"A prisoner has escaped!" one said.

"Let's get him!" the other said, flying towards him. He smirked, and sent a tendril out, wrapping it around the guard. He then sent a large volt of electricity through the tendril, shocking him. "Augh!" he screamed out, "Quick! Get reinforcements!" The other guard stumbled, and ran away as he threw the one he had into the pit.

"Yes. Go get reinforcements." he said, "I shall absorb all of their energy too." He then continued to trot along the path until he heard the sound of guards. About ten soon came into view, and he stopped.

"That's the escaped prisoner! Get him!" one roared, as they flew towards him. He just smirked as he sent out tendrils to wrap around all of them. They screamed in agony as he ripped their life force out of them and added it to his own power. He then threw them all into the pit, and continued walking.

As he went on he continued to suck out the energy of every guard he met. Soon enough he'd reached the gates of Tartarus where the three headed dog, Cerberus lay. Cerberus immediately knew that he was a prisoner, and let out a growl. Cerberus then lunged at him, it's three heads snapping at him. His horn glowed, and five tendrils shot out, and wrapped themselves around Cerberus.

He then sucked out all of the energy the monster had, which was not as much as one would think, and then slammed it against the gates, busting them open. For a moment he was blinded by the brightness of the light, but he recovered, and stared at the open desert in front of him.

It seemed that the landscape had changed since he was sent here. Last time he'd seen it it had been a dark forest filled to the brim with dangerous animals such as manticores, and hydras. "I guess a place can change in a millennium and a half." he commented.

His horn then glowed, and two wings made of dark energy sprouted out from his sides. He gave them a flap, then took off into the air, headed towards the mountains in the distance. "Soon, Celestia, soon I'll have my vengeance upon you and your sister." he said.

Finally he reached the mountain caps. He hovered over them, and looked down at the city sitting upon the side of one of the mountains. "Ah, Canterlot. It hasn't changed a bit." he reminisced. He then flew down, and landed in front of the castle, startling the guards stationed at the door.

"Halt! Who goes there?" one questioned.

"An old acquaintance of the Princesses." he said, dispelling the wings, and wrapping magic tendrils around them. They struggled, but he quickly depleted them of their magic power, and threw them off of the cliff. He then slammed open the doors with his magic powers, and waltzed in.

Along his way he found more guards, but he just took their energy too, and slammed them against the walls. Finally he had reached the throne room where Celestia, and Luna should be. He charged up the magic in his horn for a second, and then used it to bust open the door, startling Celestia.

"Yes?" she asked as she turned towards the door. When she saw who was in the door, though, her concentration broke, along with the porcelain tea cup she'd been levitating. "No! I-It's impossible!" she stuttered.

"Oh, it's very possible. I thought I told you that a long time ago."  he said.

"B-But I locked you away in Tartarus!" she said.

"Oh, you did. For over 1000 years I might add." he said.

"But how?! How did you get out Tenebris?!" she demanded.

"Oh Celestia. Did you really think it would be as easy for you to seal me as it was to seal your sister." he said, making her eyes widen.

"But how do you know that?! That happened after you were imprisoned!" she exclaimed.

"Oh, I have my ways." he told her. His horn then glowed, and the ground started shaking.

"Tenebris what have you done?!" Celestia asked once the shaking had stopped.

"Tell me or else!" she told him, her horn glowing.

"Oh, no, not just yet." he said, his horn glowing, "I can't just have you ruining my plans now can I." Then a large wave of dark magic shot out, and the glow on Celestia's horn faded. His horn then glowed again, as the ground shook for a second time. When it stopped shaking he spoke again, "Now I would love to stay, and have a reunion with Luna, but I must bid you a due." Then, in a puff of smoke, he disappeared.

At that moment the royal guard chose to burst in. "Princess! What's going on?!" asked Shining Armour, captain of the royal guard. She let out a defeated sigh.

"Something terrible has happened." she said, "Bring my student, and her friends to Canterlot immediately. I'm afraid we'll have to use the elements of harmony."
