Shifting Sand was a meditation technique taught to the Jedi Order's Jedi Initiates that focused on using the Force to levitate small particles. Initiates Dooku and Sifo-Dyas learned the technique, and in 88 BBY, used it to sneak into the Archive of Forbidden Artifacts vault in the Jedi Temple on the planet Coruscant. The pair again used the technique in 42 BBY during the invasion of the planet Serenno by Abyssin mercenaries to break into a comm tower.
Shifting Sand was a meditation technique used by the Jedi Order. Jedi Initiates were taught the meditation as a way to focus on levitating small particles using the Force.
Dooku (pictured) and Sifo-Dyas used Shifting Sand on Coruscant and years later, on Serenno.
At some point during the Republic Era, Initiates Dooku and Sifo-Dyas attended a class on levitation taught by Jedi Grand Master Yoda. They learned how to use Shifting Sand in the session, and Dooku was considered the top of his class. In 88 BBY, Dooku and Sifo-Dyas broke into the Archive of Forbidden Artifacts, a secret vault of dark side artifacts hidden within the Jedi Archives of the Jedi Temple on the planet Coruscant. At Sifo-Dyas's behest, Dooku used the Shifting Sand technique to slide sand between the door to the vault and the wall, breaking the door's lock and thus allowing the pair entry into the room. Dooku later recounted the incident to his sister Jenza via holo-letter.
In 42 BBY, during an invasion of the planet Serenno by Abyssin mercenaries, Dooku and Sifo-Dyas used the Shifting Sand technique to break into an occupied comm tower on the outskirts of Serenno's capital city, Carannia. Around 23 BBY, Dooku gave data disks of his conversations with Jenza to his recently recruited Sith assassin—Asajj Ventress—for her investigation into Jenza's location, and she listened to the message mentioning Dooku and Sifo-Dyas' usage of the technique to sneak into the Bogan Collection. After Ventress found Jenza, the latter told her of the pair's application of Shifting Sand during Serenno's invasion.
The Shifting Sand meditation technique appeared in a flashback in the audio drama Dooku: Jedi Lost, written by Cavan Scott and published on April 30, 2019. The capitalization of Shifting Sand was confirmed by the audio drama's script release on October 1 of the same year.
