Amplerix is a distant planet deprived of a natural source of light, feeding itself from the inside by fire, water, and air. The planet’s population is divided into six tiers—from the first, crowned and untouchable Queen, to the sixth, where the most powerless inhabitants of this harsh land are placed. The Queen’s fatal illness, which costs her blood to protect Amplerix’s orbit from an invasion of demonic lizards, forces the representatives of opposing tiers to unite and find a cure for their ruler. In these searches, under an eternally black sky, alliances are born, love is shattered, intrigues are woven, and terrifying answers emerge to long-forgotten secrets of Amplerix.
