Naci Davis, as a descendant of the Obscurial, holds a yew wand in her hand and fulfills her mission as a guardian with Hufflepuff tenacity. From the crisis in the secret room to the Wizarding War, she has always stood at the intersection of light and darkness. She is both the healing hand of St. Mungo's and the founder of the underground resistance network "Hummingbird".
She formed a deep friendship with Lily Evans, experienced complicated entanglements with Severus Snape, and even composed a love song in the flames of war with Sirius Black. In the final battle, she guarded Hogwarts until dawn, carefully preserving the truth about Regulus, the Potter family's relics, and all war memories, becoming the guardian of history.
After the war, as a Defense Against the Dark Arts professor, her "Art of Guardianship" became a new magic classic, and the oath she and Sirius made in the Astronomy Tower was forever engraved in the starlight of the castle.
