Revenge of Tenebris

Two ponies were standing in the middle of a courtyard. One was a light green stallion with an orange mane, and a shield as his cutie mark, and the other was a young jet black colt with a blood red mane, and no cutie mark. "One more time Tenebris." the green stallion said. Tenebris let out a growl of frustration, and slammed his hooves into the ground.

"Enough!" he yelled, "I'm tired of shielding magic! I want to learn how to fight!"

"Being a royal guard isn't just about fighting. It's about protecting those you care about." the green stallion told him calmly.

"I've had enough of your philosophical nonsense!" Tenebris yelled, his horn lighting up with a black light. The stallions eyes widened in realization. His horn glowed just as five dark beams shot out at him. They crashed into the shield he just conjured, draining almost all of his energy.

"That spell. Where did you?" he panted.

"Well since you weren't going to teach me what I needed to know I taught myself." Tenebris told him.

"But that's-"

"Dark magic? Yes I know." Tenebris cut him off.

"How did you get in?" he asked.

"Oh. It was only guarded by one simple spell." Tenebris said.

"But, that spell was cast by Princess Luna herself." he said.

"Her magic is nothing compared to mine." Tenebris told him.

"Impossible." he said.

"Oh, it's very possible." Tenebris said, his horn glowing again. Suddenly tendrils of dark energy shot out, and wrapped themselves around the stallion. "Now I'll take all  your magic for my own." he said, sucking out the stallions energy. In a few seconds he was dry. He flicked his head, and the tendrils threw him against the wall. "That's all? Some captain of the guards." The stallion lifted his head.

"You'll never get away with this." he said.

"Oh, but I already have. Next I'll suck the life out of every guard, and then I'll take the magic of the Princesses themselves!" Tenebris let out a loud laugh as he left, leaving the stallion to die on the ground.

Tartarus. Not a nice place by anyone's standards. It was a place filled with fires, and prison cells. It was patrolled by stereotypical demons. Though the ones that could really be called demons were the prisoners themselves. That's why they were in there. In one particular cell was a jet black stallion unicorn, who had no cutie mark.

A guard happened to be walking by when he noticed the stallion. He snorted. "Some conqueror of Equestria. Look at you now." he said, poking the stallion with his pike hard enough to draw blood. He snorted again. "Not gonna fight back? Prisoners these days are so boring." he said. The guard then left, leaving the stallion alone again.

After the guard left the stallion calmed himself with the thought that this would soon be over. A few hours later another guard came by, and unlocked his cell. He opened the door, and quickly stepped in, closing it behind him. "I've brought some food for you." he said, tossing up a loaf of moldy bread, and catching it again. "But first you have to beg for it." he said.

The stallion didn't move, making the guard angry. "I said beg for it." he said. When the stallion still didn't do anything he walked over, and kicked him. When he still got no reaction out of him he threw the bread down. "Fine." he said, "I'm going to torture some other prisoner." The stallion only sat up when he heard the door close, and the demons footsteps faded away.

He levitated the bread, and tentatively took a bite out of it. He retched at the taste, but still ate it anyways. The prisoners were only fed once a week, and he knew he had to keep his strength up. Finally he had finished eating. Next he decided to do a few physical exercises. If his body was weak his magic wouldn't be able to reach it's full potential.

Finally he conjured up the book he had been able to smuggle with him. It was an old worn leather bound book with the image of a skull on the front. He delicately brought his hoof across the cover, admiring the hoofwork it took to make. He flipped it open to the first page, and started reading.

He had already read this book from cover to cover many times in the thousand and a half years he'd been there, but he could never get enough of it. After all it was the only past time he had in Tartarus, and the book that originally had taught him black magic.

He flipped over to page ten, to his favorite spell. It was a magic draining spell. It was a basic spell, but very powerful if the right person got their hooves on it. It was a spell that allowed you to drain one of their magic, or life force, and add it to one's own.

He flipped over to page twenty three, another favorite of his. It allowed him to summon tendrils of dark magic to do what he wanted. He was able to use them for battle, or just plain picking stuff up. Very useful for keeping enemies still as he drained them of their magic.

He then continued to skim through the book until he closed it with a content sigh. He then cast a spell to hide the book again. The book faded from visibility just as a guard walked past. He then laid back, and closed his eyes. Soon. He thought. Soon, and I will finally get my revenge.

He thought about how he was going to destroy Equestria, and Bring Celestia and Luna to their knees. How he would finally get revenge for being imprisoned so long ago. He finally drifted off to sleep, an image of Equestria burning at his hooves in mind.
