Petra:  Keeping her breath low in the darkness, Petra did her best to suppress everything from her body that could be defined as sound. She made her small body even smaller, mindful even of the crinkle of clothing rubbing against air. She walked with her hand over her mouth, for if she did not, her breaths, more chaotic than she could remember, would make a sound from her throat.

Petra:  “—!” Petra’s light-brown hair swayed as she walked unsteadily in the mansion, which she had begun to get used to, almost like she was lost in an unfamiliar world. She was glad that the floor had a soft carpet over it. Thanks to that, she was spared from having her trembling toes hitting the floor. She vowed to gratefully wash the carpet the next time she had a chance. Were it not for such silly thoughts, her legs would have stopped obeying her completely. As it was, her tottering gait was slower than that of a baby. If she stopped, she likely would never walk forward again. She was in a long corridor with no end to it. This one time, she was tempted to hate the vastness of this large mansion she had grown so fond of.
