Force stealth

"You're the Sith Lord!"

- Anakin Skywalker

Force Concealment can be used by highly skilled Force-users to mask their Force alignment (Light or Dark), their ability to use the Force, or even their entire presence from others who are Force sensitive.

This ability manifests in different forms; Vergere would shrink her presence in the Force to a microscopic size, where she was almost undetectable and able to avoid mental attacks, even from Luke Skywalker. Palpatine was the most powerful and notorious user of this power, having hid his dark nature for over three decades from the Jedi Council, even when in the same room. Revan used the technique to shield his true light-side affiliation on Korriban in order to infiltrate the Sith Academy. Darth Traya used a powerful version of this to evade both the surviving Jedi and her Sith apprentices, as well as mask her nature from her own student, the Jedi Exile. Millennia later, Granta Omega used this power to disguise his dark-side nature from Anakin Skywalker and Obi-Wan Kenobi. It is unknown exactly which derivative of Force Concealment Omega employed. Other users included the Jensaarai, who constantly hid their presence in the Force from both the Sith under Darth Vader and the New Jedi Order. The spirit of Exar Kun most likely used this power to escape detection by Luke Skywalker when he founded his Jedi Praxeum on Yavin IV, as he was only discovered and destroyed upon revealing himself to the trainees at the academy.

It is also speculated that this is the power used by Darth Bane to escape Kaan's thought bomb.

One of the more prevalent derivatives of Force Concealment was the Quey'tek meditation. When properly applied and maintained, a Sith Lord or Dark Jedi could mask their own dark signatures appearing completely benevolent to even the most powerful and alert Jedi.

Known users of the Quey'tek meditation included Asajj Ventress, Dooku (although Obi-Wan Kenobi and Anakin Skywalker were eventually able to see through his shielding), and possibly Darth Maul. Jacen Solo also used this technique to hide Lumiya's dark presence. Jacen also used it to hide his own emotions from other Force users whenever he was upset or under stress.

Behind the scenes
In Wizards of the Coast Star Wars roleplaying game, this ability is referred to as "Force Stealth". The original version allowed a force user to not only hide his or her force sensitivity, but increase his or her ability to hide. The Revised version only provides a way to cloak ones connection to the force. Any use of the force causes this ability to fail, although Jedi Sentinels learn to use Force Stealth and Force Camouflage together.
