A mystery motif written by John Williams and performed by the London Symphony Orchestra first appeared in the 2002 Attack of the Clones soundtrack. It is an arpeggio figure in a minor key, ascending and descending in a succession of notes. The leitmotif has multiple variations, sometimes having a conjunct, undulating motion.
In the Star Wars: Episode II Attack of the Clones, the motif is first heard in the track "Return to Tatooine," in cue "2m5 Library Scene"—at the Jedi Archives, where Obi-Wan Kenobi was searching for the planet Kamino. Later, it sounds with in cue "3M1 Finding Kamino", when Kenobi first makes planetfall on Kamino and encounters its rainy environment. It is next heard in the cue "3M6 The Meeting With Fett", when a Kaminoan-ridden aiwha emerges from Kamino's ocean and flies around Tipoca City, immediately prior to Obi-Wan's meeting with Jango Fett. The motif is later heard in the cue "3M8 Rainy Ramp and Anakin's Nightmare", when Obi-Wan makes his report to the senior Jedi from a Kamino landing platform (featured in "The Meadow Picnic" on the released soundtrack). The leitmotif also accompanies the plotting of the Separatist Council on Geonosis.
A variation of the motif sounds in "Council Meeting," cue 3m1 of Star Wars: Episode III Revenge of the Sith's soundtrack, again written by John Williams. It is followed by four notes that forms the first four notes of Ahsoka's Theme, first heard in the Star Wars: The Clone Wars film written by Kevin Kiner. In the Star Wars: The Clone Wars TV series, which was also scored by Kiner, the motif appears in the episode "Voices," as Qui-Gon Jinn guides Yoda through the misty swamps of Dagobah, teaching the Jedi Grand Master about the Force and immortality.
In the 2014 Star Wars Rebels episode "Fighter Flight," just after Ezra Bridger frees farmers who were captured by the Galactic Empire in Imperial Troop Transports, the mystery motif trails the Force theme in a manner similar to that of the "The City in the Clouds" track. In the 2016 episode "The Protector of Concord Dawn," the mystery motif appears and is further developed by composer Kevin Kiner as the Spectre Sabine Wren plants explosives at the Protectors Camp on Concord Dawn.
The 3M1 cue is reused by composer Gordy Haab with some variation in the 2017 video game Star Wars Battlefront II for its Kamino loading screen. In Star Wars: Episode IX The Rise of Skywalker, the Attack of the Clones track "Return to Tatooine" is reused for the rooftop scene beteeen Zorii Bliss and Poe Dameron. The mystery motif is included, and sounds when Bliss lowers her helmet's eye-shields. In the same 2019 film, the leitmotif is played in forte, overlaying the Force drain scene and increasing in speed, pitch, and volume as Darth Sidious takes the power of Rey and Ben Solo for himself.
Variations of the leitmotif are used in various BBC documentaries released in the 2000s and 2010s.[source?]
