Oblivion

In a realm far beyond imagination, two kingdoms went to war: The Dragon Kingdom of Reilas, and The Ogre Kingdom of Urgong. The kingdoms were at war for 2 years until the ogres had almost put the dragons on the brink of extinction. In an attempt to keep her kind's existence alive, the queen of the dragons ordered her most trusted knight to take her egg and run far, far away-as far as he could in order to keep her unborn child safe. But on his journey, the egg was stolen by bandits and sold to an assassin, who took it to another realm: The Human Realm.

The child was born and raised in The Human Realm, and the assassin tortured and turned her into a cold-hearted, loveless killing machine. Combined with her immense magical powers, she was practically invincible. But she never used the powers for what her mother intended her to. Instead, she turned the fairytales of evil, fire-breathing dragons into a reality.

But when she discovers her origins, she's going to take what's rightfully hers: her throne. And when she gets to it, there is going to be no mercy for any kingdoms.
