About
Sierra is the eldest of the Vanille sisters. She takes after her father, sporting the familiar silvery hair and blue eyes that her family are famous for. Her horn is pure white and curved. Her dress sense is usually less than elaborate, looking more for practicality than anything else. She's a seasoned fencer, and rides horses frequently.

Personality wise, Sierra is described as fiery. Having been raised as a lady, she knows exactly when to act refined and placid, but enjoys company in which she can be brutally frank and more outgoing. Her temper - though flaring less frequently than Gabriel's - is the stuff of legends.

Even before Gabriel took to the throne, she was intended for someone important to wed. When the chance arose, it was Oswald, a long time friend of the family, who chose Sierra as a potential bride for the young King. Whilst knowing her duty, Sierra had a few doubts of her own. Her love for her country shone through, and after the night on which she accidentally killed Rafiel, she began to see a softer side to Gabriel which she liked - even loved.

In Seven Wonders, it is revealed that Sierra has a half-sister by the name of Niobe , after her father remarried. She is also the mother to two young adults -Lucas and Misha Cristata, both of which are unicorns like she and her husband.
