My name is Malum Prohibitum. I grew up alone, not knowing my family. My father was killed during a trial, and my mother was a thief who stole more then she bargained for.

One year after I revealed that my mother was the one to end not only her own life, but that of her sisters, a run of killings have occurred. . . and most of the suspects appear to be changelings. Now, I must find the truth behind them, if I am to help Princess Heart and Princess Celestia successfully complete the changeling merge.
