The corrupted organ in Notre-Dame blocks the way forward; play the melodies on the zodiac floor keys in the Great Organ Room. Each melody comes from a Melody Sheet, and each one clears a different corrupted path once you land on its keys in the right order.
Quick answer: Land on the floor keys in these orders. Fugue: Moon, Sun, Moon, Virgo. Sonata: Sagittarius, Capricorn, Pisces, Aquarius, Capricorn, Sagittarius, Capricorn. Concerto: Gemini, Cancer, Virgo, Leo, Virgo, Leo, Gemini.
Why the organ is blocking the way
In the Transept, purple corrupted pipes seal the path. Inspecting them brings up the note titled “THE CORRUPTED PIPES OF THE NOTRE-DAME ORGAN”, which reads: “This is the noxious work of Death. He’s corrupted the pipes connected to the organ.”
A Spirit under the stairs in the Great Organ Room points you to the fix: “Find the melodies of Music Masters of Notre-Dame, and you shall clear this corruption.” Each melody you play restores a section of the organ and opens a route that was sealed.
The 14 zodiac floor keys
A row of 14 floor keys sits under the giant organ, each marked with a zodiac symbol shown on the floor beneath it. Read from left to right, the order is:
- Aries, Taurus, Gemini, Cancer (keys 1 to 4)
- Leo, Virgo, Sun, Moon (keys 5 to 8)
- Libra, Scorpio, Sagittarius, Capricorn (keys 9 to 12)
- Aquarius, Pisces (keys 13 and 14)
There is no button prompt; a key plays whenever you touch down on it, whether by jumping, walking, or sliding across. It sinks, glows, and projects a green beam upward as a chime rings. Finish a melody correctly and the organ flashes green, with a glowing clef appearing in the pipes.
Fugue of Notre-Dame
The Spirit below the stairs in the Great Organ Room gives you the Melody Sheet for the Fugue of Notre-Dame. It has a bass clef and four symbols printed in left-to-right order.
Play by landing on the keys in this sequence: Moon → Sun → Moon → Virgo. Counting along the floor row, Moon is key 8, Sun is key 7, and Virgo is key 6. After the final key, the organ flashes green and a glowing bass clef appears in the central pipes. The route on the right opens to the Collapsed Crypt.
Sonata of Notre-Dame
The Melody Sheet for the Sonata of Notre-Dame comes from a Spirit in the Sealed Scriptorium, who says: “Accept my final sonata to heal our sick Notre-Dame. May it bring us back to light.” It carries an alto clef and uses seven keys, all on the right side of the row.
Land on the keys in this order: Sagittarius, Capricorn, Pisces, Aquarius, Capricorn, Sagittarius, Capricorn. In the floor row, Sagittarius is the 11th key, Capricorn the 12th, Aquarius the 13th, and Pisces the 14th. When it resolves, the pipes light green, chords play, and a green dome flash goes off. The path to the right opens.
Concerto of Notre-Dame
The Melody Sheet for the Concerto of Notre-Dame comes from a Spirit at the top of La Fleche, who says: “Take this concerto to cure our fair Notre Dame of this tragic misfortune.” It carries a treble clef and uses seven keys, all on the left side of the row.
Land on the keys in this order: Gemini, Cancer, Virgo, Leo, Virgo, Leo, Gemini. In the floor row, Gemini is the 3rd key, Cancer the 4th, Leo the 5th, and Virgo the 6th. When the last key plays, green floods through the organ and a glowing treble clef lights up in the pipes.
Each Melody Sheet also carries the banner “NEW CLUE ABOUT THE SHADOW”. The Shadow is Death’s Arcana, and after the Concerto the route ahead leads to the Transept, where the fight with Death follows.
