The Black family motto is "Toujours Pur," which is French for "Always Pure". It is a reference to the Black familys belief that wizard blood and Muggle blood should never mix. The motto is featured in the main story quest "The Polyjuice Plot" in the game Hogwarts Legacy, where the player must discover it to gain access to the headmasters private quarters. During the quest, the player must speak to Scrope and choose the dialogue option "Its to do with purity of blood" to learn the motto. However, there is no penalty for choosing the wrong answer, and any of the choices can be selected to eventually obtain the password.
