The year after his father was placed on "sick leave" by the Ministry of Magic, he disappeared from the "Ministry of Magic Staff Directory".
Belladonna Rozier knew it wasn't a disease—it was an erased record. She walked into Hogwarts and into Slytherin with her father's notes. Everyone there was taking sides, but she was the only one looking at how the rules were written.
Malfoy wanted to win her over, the Clan Elders wanted to sell her, and the Ministry of Magic wanted to erase her. She didn't follow anyone - she only did one thing: make herself the center of gravity of Slytherin.
From the isolated orphan Rosier, to the talker who everyone is waiting for her to speak, to the person who rewrites the rules of the Ministry of Magic - a rose does not reveal its color, and people know their roots.
Her name is Belladonna Rozier.
