The greatest (and most troublesome) alchemist of the Itatlon Empire, Buell Osei Divan Princess, was exploring the ruins of a new star region when a damaged ancient magic array accidentally pulled him into a spatial rift, leaving no trace of his body. After countless years wandering the void, with his soul on the verge of vanishing, Buell was unexpectedly summoned to an unfamiliar plane by a bloodline-sacrifice magic array. Taking the opportunity, he used the Philosopher’s Stone to recreate his body, only to discover that his summoner was a descendant of a distant uncle from his family who had gone missing long ago. The summoner had sacrificed his soul, and his one hope was to restore the family’s former glory and continue its bloodline. Restoring the family’s glory would be easy for a master alchemist, but continuing the bloodline would be much harder. An alchemist who possesses the Philosopher’s Stone cannot have children with ordinary mortals. What’s more, the magic in this plane was primitive by comparison, not even having reached the level of interstellar civilization. It was as primitive as could be. So Buell decided he should find the two humans with the strongest Princess family bloodline in the world and have them produce a few children with an even purer bloodline. And so, on the eve of the Christmas when he had just lost his parents, young Severus Snape, a gloomy, awkward victim of school bullying in his second year at Hogwarts, gained a mysterious great-uncle as his guardian... Meanwhile, far away in America, young Oscar Cabodiri, a vain, peacock-like scientist who judged people by their looks and believed in no gods, felt a chill run down his back... He had no idea that the scientific world he’d lived in for more than a decade was about to switch channels to fantasy...
