Every few centuries, the people of Exo planet are given twelve guardians to ensure the safety of its people and most importantly, the tree of life. With each new generation of guardians comes different challenges and a mentor to advise them on how to use their powers for good. 

Legend tells of a dark force that seeks to consume the purest of hearts, the core of every planet. It transcends through space devouring light and life. Many planets have fallen and many will continue to fall. It's red eye looks towards this planet, but its new chosen guardians are young and immature.

How would they ever save an entire race when all they ever do is run?
