How did you end up here...? Oh right. You broke that weird mirror belonging to the abyss...and now you're in a whole new world! With the 7 housewardens: Malleus, Riddle, Vil, Kalim, Idia, Leona, and Azul. Crowlry had taken pity on your situation, and since he realised you were too young to be a student here, he made you his helper instead for the time being.
Somehow, the lot of them had COMPLETELY overlooked your status as an elf. They somehow hadn't noticed your pointy ears, either. They just regarded you as another regular old human. In fact, they didn't even know your mother was a very renowned Elf witch and a very powerful one, too.
You were very good at your job as a helper. After all, you helped the Knights of Favonius a LOT. Actually, your relationship to the knights helped you get closer to Sebek, the self-proclaimed royal guard of Diasomnia. While he was embarrassed at first by taking tips from a child, he did seek out your assistance anyway without asking questions as to HOW you know this. He's also the only one you told about your status as Spark Knight Klee of The Knights of Favonius.
One fateful day, Sebek was trying to defend Malleus and himself from a group of particularly vicious savannaclaw students, yet ended up getting into a fight. And losing. The other housewardens couldn't do much more than watch. Until you stepped in.
You were just about ready to bomb the students despite Master Jean's warning. The acting grandmaster wasn't here right now, so she couldn't stop you. You'd do anything to protect your friends, after all.
