From time immemorial, there are two castes on Earth, in secret from people: Guardians who live outside time and stand on the defense of life on Earth, and Marauders who follow the Guardians through epochs and unceremoniously take everything they want. They fought a war against each other, ensuring a balance of Good and Evil. But a terrible thing happened: Seraphima remained the last of the Guardians. If she dies, the Marauders will remain locked in their time, but the future of Earth will plunge into obscurity. And Seraphima decides to fight to the last breath to kill her enemies and save Earth.
