"With eyes as blue as the ice that traps the streams,
and hair as white as the snow that falls in winter,
she will bring chaos and flame.
With the Hellbringer's mark bestowed upon her,
she will drive the world to its knees.
and know what she will uncover."
Alexandra has never known her parents. She was abandoned under a tree when she was just a babe, and an adventurous boy from the nearby village stumbled upon her. He carried her back to his village and to his parents, and together, they raised her like their own.
Now Alexandra has turned 18, and, along with others, is going to be chosen by her soul-tie when the moon is at its highest. Her wish is that she is chosen by an apex predator of sorts so she can join the Royal Knights, but what she gets is much more powerful--and bigger--than what she expects. So powerful, that she is personally selected by the Prince to be his personal guard.
What creature could possibly cause all of this? Simple. A dragon.
