"Ha! Hufflepuffs standing up to you? That's a joke, mate!"
"Yeah, but it's funny, right?"
Two third-year Gryffindors were walking to Charms when a dark shape whistled past them and landed on the floor in front of them. It was some odd girl wearing a cape. She was pretty average, really, but for the cape, the black pants, the black long-sleeved T-shirt, the black Converse, and the black fedora she was wearing on top of her brown hair.
"Were you just dissing Hufflepuff?" the odd girl with the cape asked dangerously.
"N-n-nooo!" one of the boys squeaked.
The odd girl's eyes flashed. She reached into her pocket and pulled out a Recorder, a magical tape recorder. She hit a button on it and played back the conversation.
"Ha! Hufflepuffs standing up to you? That's a joke, mate!"
"Yeah, but it's funny, right?"
"Would you like to change your answer?" the odd girl asked softly.
The boys nodded.
"Now, you should know, I don't like Gryffindorks. They're annoying and they smell funny. But I especially dislike Gryffindorks who mess with my House. Do you know who I am?"
The Gryffindors shook their heads.
"I am Cassiopeia Rodgers! My mother is the daughter of Bellatrix Lestrange and You-Know-Who! And my father is even more dangerous. My father is a Dementor who guarded Azkaban. And you know what that makes me?"
The two boys gulped simultaneously.
"Dangerous." She reached into her pocket again and pulled out a dark gray rectangle with rounded sides. "This is made of a Dementor's cloak. It sucks happiness out of you. It sucks out your soul." She grabbed a girl walking down the hallway and brought it down on the girl's wrist. With a crash, the rectangle formed to fit around the girl's wrist.
The girl screamed. Then Cassiopeia pulled the rectangle off of her wrist and unrolled it. With a snap, it reverted to its original state. The girl who had just been tortured looked at Cassiopeia, and asked in a shaky voice, "Who are you?" The girl ran down the hallway, her sobs echoing off of the stone walls.
The two Gryffindors took a step back.
Cassiopeia slapped the rectangle around her wrist. "This doesn't bother me, because I've killed before. That's the way to gain immunity to things like this. And I'm not afraid to do it again. Now, before you run off like the cowards you are, just remember something: I'm a Hufflepuff. And I'm not the most dangerous one."
The two boys turned around and ran back to the Gryffindor common room. Cassiopeia stood there for a second, and then called out, "Okay, Penny, you can come out now!"
The girl who had been tortured, Penny, walked around the corner, doubled over in laughter. "Did you see their faces, Cassandra? I think one of them peed himself!"
Cassandra laughed too. "If I'd known that all it took to get even with the Gryffindors was a Recorder, a cape, and a slap bracelet with the paper ripped off, I would have done this years ago!"
