- "He stares at the monolith before him, lifts his wand and begins to chant eerily. The surface of the cabinet glimmers, atremble in the ambient light. Almost alive. Then he stops. Looking back, his eyes haunted, he slips away. Light plays within the cabinet. Movement. Shadows flicker within, coalesce."
- —Description of the charm being used by Draco Malfoy[src]
Harmonia Nectere Passus was the incantation of a spell used to repair a broken Vanishing Cabinet and perfect its performance. It required more than simply speaking the incantation in front of the damaged device, as proven it took Draco Malfoy a year of effort to fix it.
Draco used this spell on the broken Hogwarts-Borgin and Burkes Vanishing Cabinet pair in the Room of Requirement at Hogwarts School of Witchcraft and Wizardry in the 1996-1997 school year, which had been damaged by Peeves in 1992. By 30 June, 1997, after a year's worth of painstaking efforts, Draco succeeded. Granted, Draco was working off of Borgin's instructions instead of bringing the damaged cabinet over for him to see firsthand, which hampered his efforts.
In Latin, harmonia means "harmony;" nectere means to connect or tie together; and passus can translate to mean "spread out," "extended," or "open," but may most likely be a Latinisation of the English word "pass."
