When young Heart, a pony with pink hair, meets ZACH, a blue dragon, they set out on a journey of immessurable proportions to stop the evil Anti-Hero, a phoenix who believes his destiny is to destroy the world. Along the way, ZACH and Heart meet some valuable allies, such as the Rogue, a white she-wolf who wants revenge on the Anti-Hero, whom she was trained by (which is what the Anti-Hero regrets the most), and also whom tried to kill her while they were once allies, Jason, a white tiger who is very loyal to Heart and ZACH, and the Auracle, a blue dragoness surrounded by a light blue Aura and has the ability to see parts of the future. Now they must begin the quest that could mean saving the world from an apocalypse that has the power to destroy the entire world. Will ZACH and Heart succeed, or will they lose their homes to the darkness?
