Retribution
Chapter 1: Secret plans of Return
"Hey" a silent mares voice said, "I need your help."
Apocalypse opened his eyes slowly and looked around in his dungeon to find the source of the voice but nopony else was in the room. "It must have been a dream" he thought.
"Hey! I need your help to escape from here", the voice whispered again.
"Who are you?" he yawned, "And where are you?"
"I'm a foe of Firestorm and therefore I'm a friend of yours." the voice whispered in his ears ignoring the other question.
"And how should I help you? I'm banished to this place. I can't leave hell." He said.
"I have something that might help you." The mysterious voice said as it died away, "Meet me tomorrow at town square."
"Wait! How should I meet you when I don't know who you are?" he asked but soon he realized that the voice had been gone.
He lay back down on his plank bed and was wondering if the voice was an illusion of his mind or if there is somepony who really wanted his help to escape and who this mysterious mare was.
In the next morning he decided to go to the town square to be sure that there was somepony who needs his help. After he had arrived he stood next to the fountain and waited for the mysterious mare. About half an hour later he heard the voice again "I'm glad you could make it." The voice whispered.
"Where are you?" Apocalypse asked with a bad feeling about this whole escape plan. "I'm behind the tavern." he heard the voice answering.
He went in the direction of the tavern as he saw a shape with a black cloak disappearing behind the building. Now he has the opportunity to find out who the mysterious voice belongs to. As he arrived he recognized that there was nopony behind the tavern. With a trail of frustration he asked: "Is there anypony?"
"Yes. I'm straight behind you." he heard the voice chuckling which made him feel a bit scared.
Apocalypse turned around just as the pony with the black cloak appeared out of nowhere. Even now after she pulled down her hood he saw that the mysterious mare was a bright blue unicorn with a pale blue mane.
"Why isn't your horn cracked as the horns of the other banished unicorns?" he said amazed.
"I used an illusion spell when Firestorm banished me so I could at least secure my horn. But that's not important. I need your help to escape from here." she said.
"But it is impossible to esca…"
"Impossible if you haven't got one of these." the mare interrupted him while she pulled an earring with a glowing purple gem hanging on it out of her mane.
"I-Is this w-what I think it is?" Apocalypse stuttered as he saw the glowing gem.
"It is one of the jewels of destruction." she said after she stored the gem back in her mane.
"How have you managed to bring him here down to hell?" he asked.
"Well…I stole it from Firestorm while he was banishing Me." the blue mare said with an evil smile on her face.
"You have a jewel of destruction and you need my help to escape from here? …" he summed up, "I might help you if you help me to take revenge on Firestorm."
"It seems that we have an agreement then." She smiled, "But how should we escape?"
"That's easy. We have to find one of those elite soldiers and manipulate him so he will open us the gates or we find a special demon that can dig us a way out." he said with a grin on his face while he thought about his revenge.
