"-she wrote several books that have survived through the centuries, including Murder on the Orient Express." Calista continued to scroll notes across the chalkboard, ignoring the quiet conversations going on around her. "Agatha Christie was widely said to be the best writer in her time. She-" Calista froze, the chalk tumbling from her hand, as a terrifyingly familiar sound filled the air. Her whole body reacted to the sound of an attack.<br/><br/>She spun, eyes wide, and seized the closest child to her. She stuffed him under the desk, shouting at the others as she did. "Down<span style="font-style: italic">now</span>! Do not come out until I say!" She snatched up her bag and sprinted out the doors, her heart pounding in her chest. Despite the panic running through her head, her hands were steady as she pulled a small gun from her bag. As she stepped through the door the ground tremored and a resounding boom echoed through the building. Something had hit the ground. She braced herself for an explosion, but nothing happened.<br/><br/>Slowly, she peeked her way around the door frame. There, in the middle of the ruined playground, was a tall, round metal object. A faulty missile perhaps? She held the weapon in front of her as she crept closer, nerves on high alert. As she slowly circled the object, she spotted what looked like doors. Despite the devastation around it from it's landing, it appeared to be undamaged. She came to a stop in front of the doors, about to call out, when something started to happen. Slowly the thing flickered, and then changed. She took a step back as her heart jumped into her throat.<br/><br/>Standing in front of her was an ordinary outhouse; if she hadn't been looking right at it when it changed she wouldn't have given it a second glance. What black magic was this? A sound from behind her caught her attention, and she turned to see a gaggle of frightened students huddled behind her. She forced a calm smile onto her face.<br/><br/>"Class is dismissed for the day; I'll see you tomorrow morning." They glanced from her to the building behind her, but they all knew better than to argue with what was clearly not a request. One by one, they turned and started away towards their homes. Once they were all out of harms way, she turned her attention back to the building in front of her.
