Guardian: The Great Beginning

Lunaria is a perfect world of peace and balance, located in a different time and universe than the Earth we humans live on.
It is ruled by divine creatures called Spirits, who are in charge of all the energy that flows through the planet and its inhabitants.
When the youngest Spirit, Asura, in a desperate attempt to follow along with his older siblings, whom he feels left out and mistreated by, accidentally meddles with the Darkness that lurks within Lunaria, things go desperately wrong.
It is up to his eldest sister, Akilah, to find a way to save both her little brother and the world from the Darkness and prevent it from consuming the entire world.
The question is, however, whether or not Asura even wishes to be saved anymore.
A battle between light and dark commences, with Lunaria's fate in the balance.
