One fateful night, Harley and her best friend discovered an astonishing secret: their horses possessed extraordinary abilities. This revelation led them to a hidden Realm, a gathering place for horses and riders from across the globe, each transformed by a mysterious power. Within this Realm, Harley learned of their true purpose: they were selected for the Race for the Realm, a perilous competition fraught with life-threatening challenges, monstrous creatures, and relentless mercenaries driven by a desire to exploit the horses' powers. Faced with a critical choice, Harley must decide whether to abandon Angel and return to the safety of her home or embrace the risk, joining the Race to fight for their place as Protectors of the Realm.
