Guardians of Alleira: Beginning of Journey

Long, long time ago humans and creatures which we now consider magical, were living together on a planet called Keraciah. They all existed with each other in harmony, until there was a war between human, demon and dragon tribes, details of the incident kept a secret by The Royalty. Since then, humans (along with "nonmagical" animals) and the rest of the creatures got separated by the first group of the dragon Guardians into two individual dimensions, in two different solar systems: the Earth, and the Alleira. The strongest demons got locked in the underground prison - Heige. However, some of the smaller and rather harmless demons got stuck in between these two worlds, yet still unnoticed by humanity.
Now, the only people who can travel from one dimension to the other are the halfblood humans: the rare children of both human and a "magical" creature.

Humans and the other races were living in their own worlds in peace, not bothering one another. It was like an endless paradise taken out of someone's dream, you could say. Or at least it were like that until the Demon King, Uzlaregh, was awakened and released from the Heige by the traitor of Fiereye Tribe - the Fire Element Royalty. Traitor made a pact with Uzlaregh, willing to kill anyone who stands on their way in connecting these two dimensions, making the chaos rule in both of them and stealing all the Guardians' Elements, becoming the most powerful creature on both planets.

Will the new generation of Guardians be able to defeat the traitor, protect both worlds and find out the history behind all those events which were taken to the grave by the first Guardians centuries ago? How will Ashford, the main character, handle all this responsibility which has gotten on his shoulders when entering the Alleira for the first time?
