Her ambitious younger sister.

Julia Livia Cordelia, or Livia for short, is the younger sister of the crown princess Ariel, and as such, she's the next in the line of succesion, should anything happen to her beloved sister.

Always living in the shadow of her more talented and beloved sister , Livia's life has been nothing but frustuation and boredom, for she knowns that as a regular princess, whatever her ambitions and dreams might be, her ultimate destiny is going to be either married somewhere off, or to spend all her life as a vestal priestess. Things that she doesn't want to become, for she wants to rule!!.

But between her current situation, and the dream she aspires to be, there's a problem in the middle, namely, her sister, for if she wants to become queen, she needs to go out, but it isn't she's gonna assasinate her, hell no, she's isn't that cruel!.

Instead, to achieve her goal, she's gonna make use of a ancient clause on the rule of succession, that stipulates that, should the current heir be deemed incapable, he or she, can have his/her claim removed. Which is exactly was she's looking to happen.

By secretly sabotaging her image with well placed pranks and schemes, Livia hopes that Ariel will be declare incapable, so that she will be the one to rule the kingdom, and what better way for it to happen, but for her to leave Ariel humilliated in front of everyone. But before she can put any kind of plan into motion, she's gonna need one to begin with.
