Remember all those Disney Princesses... They were always the "good girls" being abused by the bad guy (usually an Evil Queen or Witch)? Lucinda's story is the exact opposite of that; she's the Anti-Disney Princess. Her folks were the evil rulers of a trans-dimensional empire that they ruled with an iron fist; but as stories like that tend to end, the forces good... usually show up and kill the evil mother and father.
So far we have an evil Princess (and her much less evil older sister) left as orphans by the good guys....who somehow ends up on earth; I could tell you more but that would be spoiling the fun.
