The Universal Trouble sent a long winter to the earth and left many orphans. Hard times have come, full of grief of loss... In a strange family, in a remote village, a foster child grew up - the miraculously saved Prince Svetel, heir to a once powerful empire. He decides to become a knight in order to find and save his parent’s son Skvara, who was forcibly taken away from home. And so Svetel, yesterday’s boy, walks in military formation under the sky of eternal winter. He adjusts his homemade harp, endures the ridicule of his elders, the hardships of the road, the pain and bruises of training. All in order to one day, having become a hero and leader, smash the Black Five stone by stone, and rescue his beloved brother! Meanwhile, sometimes the path of Skvara, who has become a secret warrior, winds through the hills and wastelands very close by. A shadow in the darkness, a whirlwind of weightless drifting snow, the shine of a swift knife... The brothers’ paths either converge almost closely, then diverge again. Are they destined to meet? And in the underground book depository, a small light does not go out day and night. A young scientist, busy with peaceful research, feels the breath of secrets that can shake the royal thrones. And then one day a chain of events starts, leading to an unexpected break...
