"Tell them that tomorrow is the day to start breaking the forcefeild."
"Yes my queen"
Crystal stopped as she heard the words. She put her pale blue ear up to the door. She carefully brushed her sapphire mane from her face and listened.
"We will storm Canterlot as ordered, but is the real Cadence captured?"
"She has been dealt with."
Crystal gasped at the words. Then she decided to peak through the door.
"Changelings" she whispered in shock. Queen Chrysalis looked that way and pulled her in the room.
"Eavesdropping, were we?" She hissed, and stared at the unicorn filly she was levitating.
"P p p please. D d don't h hurt me." Crystal closed her eyes in fear, and a green light surrounded her.
....................................... .
"H h h hello?"
"Finally awake, are we?" The familiar of the Changeling queen.
"Where am I?" Crystal asked as her horn lit the Crystal Caves.
"The Caves under Canterlot. Once home to greedy unicorns who wanted the gems found inside, and now your prison."
"No one can hear me from down here, so there's no point in yelling for help."
"The others had trouble with that part."
"Why did you send me here?"
"I can't have you interfere with my plans to take over Equestria. I could just kill you."
"Please! Let me free! I promise not to tell anypony!" Crystal was afraid as she could be. After all, a queen just told her she could have killed her.
Now, if Queen Chrysalis actually thought about it, she would have realized she was scareing a filly who meant no harm, but she found Crystal as a threat to the mission.
