|Aqua Eructo spellbook|
Prior to 1994
The Aqua Eructo spellbook is a book containing information on, and instructions of how to perform, Aqua Eructo. It was owned by 'Professor' Bartemius Crouch Jr. (disguised as Professor Alastor Moody), who kept it in a room of the Defence Against the Dark Arts Classroom in Hogwarts Castle for unknown reasons. Harry Potter, Ronald Weasley and Hermione Granger later came across it during the 1994–1995 school year and used it to learn the spell, which proved valuable against the Salamander which Professor Moody (Crouch) had kept in the room.
