A Nightmare's Crystal

Nightmare Moon grinned. "We're almost done, my dear." Her horn began to glow. Crystal began to panic, but then calmed. Nightmare Moon had her under a spell. She was making Crystal a supporter... a soldier... a slave. When it was over, Crystal was freed from the stocks and given a dark set of armor. She put it on and walked to Nightmare Moon.

Nightmare Moon laughed evilly. She had done it. She had turned one of the most powerful ponies into a slave. She grinned, as she watched over Ponyville, Crystal by her side.
