In the world of Zidiya, 600 years ago, a catastrophe occurred, later called the Fall. Under the blows of the allies, the Empire of the Night, created by vampires, collapsed. And today, the pitiful remnants of their people are hiding around the world in the hope of surviving and finding the Night Stone, a powerful artifact that gives the opportunity to return to their former greatness. The mission of return is entrusted to Paola, a vampire whose chance encounter turned her into an exceptional entity. But there are many obstacles on the way, which are almost impossible to overcome alone.
