The Ninth Sister is an Imperial Inquisitor in Star Wars Jedi: Fallen Order, released in 2019, where she hunts the surviving Jedi Cal Kestis. Armed with a spinning double-bladed lightsaber, she serves as one of the game's most intimidating early bosses, and her weapon's harsh ignition has become a recognisable audio cue for fans. Short clips of the sound now circulate on soundboards and in fan edits, where creators reuse it to signal an Imperial threat or a powerful dark-side character without needing footage from the game itself.
