The final siege. Breach the gilded halls of the Forbidden Citadel, unravel the 66-day conspiracy, defeat The Grand Preceptor across three epic phases, and claim your ending.
The towering capital citadel of the Empire. Golden tiled roofs, vast marble courtyards, and celestial astrology chambers defended by elite Imperial Dragon Guards and mechanoid siege engines.
Ensure all 7 Heart Elixir Flasks are upgraded and the Prototype Alchemical Stabilizer from Part 4 is in your inventory if aiming for Ending 3.
Sprint across the great marble causeway, using your grappling hook to evade the Dragon Ballista fire. Wall-run along the vermilion outer ramparts to flank the artillery gunners, then drop-assassinate the gate captain to unlock the inner palace courtyard.
Inside the Celestial Astronomy chamber, rotate the bronze zodiac sphere until the Dragon constellation aligns with the North Star. This opens the golden elevator descending into the Throne of Eternity where The Grand Preceptor awaits.
Soul confronts the mastermind of the empire, The Grand Preceptor, an ancient sage who commands forbidden dark alchemy and celestial sword techniques.
Boss Profile: The ultimate combat test combining martial arts, clockwork sorcery, and celestial energy.
Ending 1: Vengeance of the Assassin (Standard Ending)
If you destroy the heart altar and execute the Preceptor without collecting the stabilizer, Soul avenges The Order's patriarch but peacefully passes away as his 66th day reaches its twilight beneath the falling cherry blossoms.
Ending 2: The Emperor's Shadow (Dark Ending)
If you accept the Preceptor's dying proposition and absorb the dragon core into Soul's artificial heart, Soul claims the imperial throne for himself, becoming the new sovereign master of the shadows.
Ending 3: The Eternal Blade (True Secret Ending)
If you collected the Prototype Alchemical Stabilizer in Part 4, Physician Sui administers the compound directly into Soul's heart before the final battle. The heart permanently fuses with Soul's lifeforce—curing the 66-day death sentence and allowing Soul to ride into the sunset as the immortal protector of the realm.
