The Vials of the Princess

In the Crystal Empire, an empire located on the utmost north of the continent, Eugénie is the only daughter of the Archduke. Being that, she is one of the most influential women in the empire but for her this isn't enough: Eugénie wants to be the most powerful. The only problem is that the emperor just married a new empress and, what may be worse, she originates from a common family. But she has her eyes set on a new way to power and she will stop at nothing to get what she wants.
