A world of secrecy and adventure awaits, following the exploits of Tim and Terranis. Tim is a young man living an ordinary life. He has friends, works at a job, and is part of a secret society known as the Mimics Creed. Sworn to protect the Blood of the Earth, an ancient race of shapeshifting creatures, Tim carries out the duties and responsibilities of a Keeper, a guardian of their secrets and culture. However, a sinister plot causes him to question himself, eventually sending him away from his hometown with Terranis, a warrior of his race. As the two set off to venture around the world, they stumble upon more than they can chew: a threat towards both Humanity and the Blood of the Earth. As they face the Superii, the H.A.N.A group, and many more, their strange friendship will be put to the test. By forging new friendships and meeting new allies, the duo hopes to stop that which threatens all. And maybe someday, both worlds may live together in harmony.
