Callie stared out of the broken glass window of her tattered and beaten home. Or, what she considered it to be. She was forced from her home by the Mechas, sentient humanoid robots that were created to defend the country, but ended up destroying it. Now, every human was in a constant state of peril. The Mechas were after the human race, adamant to make humanoids the dominant race on Earth. Every human they found was either destroyed on spot or taken into custody for brutal torture. All remaining humans had to learn to survive, and quick. Including Callie. Hearing a noise behind her, she readied her stun gun. Stun guns are the only weapons that can permanently disable a Mecha, interfering with their core processing system and shutting them down. The gun was also lethal to humans. She looked over the rim of broken glass carefully, bracing herself for an attack. However, she stopped herself when she saw who it was. Lowering her gun and smiling, she stood and looked at the newcomer. "It's about time you showed up." She said playfully.
