Dead Prince at Hogwarts

When the dark wizards of Knockturn Alley put their dirty hands on the long golden needle on the chest of ten-year-old Ful Sanks, what they awakened was not a lamb to be slaughtered, but a sleeping ancient dragon and the lord of death. The red and black dragon thunder entwines the end of all things, turning living people into withered bones. Foer, a boy who possesses the power of the ancient dragon at the junction and the rune of death, but only wants to make friends and have fun, has since entered the Ministry of Magic's watch list, and is pleased to mention a temporary guardian with billowing black robes and a face darker than the bottom of the cauldron - Severus Snape. Carrying the lamenting dead prince's staff made of bones and dead wood, and carrying a raven "Sangbiao" who was proficient in Snape's poisonous tongue, Ful Sanks stepped into Hogwarts.
