Earth is the first planet to have survived a war with Hunters and still have their element crystals intact. Fifty years have passed since the death of the Element Guardians and nobody knows where the crystals are. Though the realm still possesses the chance of new Guardians appearing, things have looked grim for the last fifty years - and as a result, all hope is lost. Terra turns fifteen within the next five full moons. Like every human left on the planet, she is a slave – the server girl to Hunters from day till night, only allowed a few hours of sleep. Survival was all she focused on, until her grandmother's life is taken by the cruel treatment of the Hunters. Now, Terra wants revenge. But what can a small girl like Terra do to a whole race of a ruthless alien species? She’s just one human girl, no magic, no nothing, just like three other adolescents who want nothing more than to restore human kind and the mortal realm. They have absolutely no power over the Hunters. Right?
