There were too many hallways in the dungeon, it was a danger to an adventurous girl like Charlotte.  With a quick look at her watch, she had determined that there might be enough time to check one of the passages for... she didn't know, buried treasure?  A magic sword?  She didn't have a clear idea in her head of what she might find.

She thought she might have actually found something when she heard someone calling for help.  A girl, she thought.  A Damsel in Distress!  Like in story books! She followed the voice; it was muffled, but the enclosed walls still bounced it back and forth, echoing it from its source all the way to Charlotte.  She got to the point where she thought she must be right on the other side of a wall from the damsel in question, and she saw no door.  

"Hello?" she called in through the stone wall.  "Are you stuck?  Stand back," she said, remembering what had happened on the train when she had waved her wand, "I'll get you out."  She got her wand from her pocket and pointed it at the wall, producing a shower of gold and purple sparks, hoping for what, she wasn't sure.
