GUARDIANS OF EZLYANIAS STORYLINE

AILITH is a 19-year-old orphan who lives with Mr. and Mrs. Freddy, her adoptive parents. One day, Ailith and her childhood friend, Florent, encounter a creature like no other. Dangerous. Bloody. Wounds. All in all, not a pleasant experience for either of them. Then someone appears. A female with a slim, but muscular figure, intersects the creature. She holds one heavy metal sword; its blade engraved with ineligible letters and its hilt embroidered with sparkling red stones. She raises her sword hastily and decapitates the creature in one swift swing. Her abnormally sharp jaw tightens as she observes the bloody mess in front of her disintegrate into a glitter-like particle and get swept away by a gust of wind. 

 

Who is this female? How come Ailith could see this horrible creature, to begin with? How did her parents die?
