Alys (last name unknown) (b. c. 1985) was a student who began attending Hogwarts School of Witchcraft and Wizardry in 1996 and was sorted into Hufflepuff. In her first year, she was taught Potions by the Potions master, Professor Horace Slughorn. As Alys was clearing up her things with the other students, Slughorn called to her, and reminded her to take the rat tail she had left behind on the desk.
In 1998, Alys participated in the Battle of Hogwarts against Voldermort's Army. Minerva McGonagall believed she was too young to fight, but Alys decided to fight for her life. Alys was able to survive the battle and was able to learn the patronus spell by summoning a huge elephant that bashed several Death Eaters.
