An idea I had that's kinda similar to the "Secrets project", is the "Wrong Road" idea. This is where your character would be if they decided to take the wrong path in life. This is to say they took the "Evil" or "Dark" road.
In Riona's she was fed up with waiting for her father, filled with Sorrow and anger she left the daycare to pull mischief to make herself feel better. and oddly enough, it did, slowly the pranks grew worse and worse, until she learned how to properly wield her attacks. Eventually the pranks became chaotic, she was burning down houses, ruining public and private property, permanently damaging important sites. She was out of control. When referred to she was often called "Hellfire" From the destruction she caused from her incinerate attacks.
Note: Riona creates an illusion to make her look like her collar fur is on fire when she uses Incinerate to it's full potential. The illusion is involuntary.
