A Void in the Force was a rare and nearly unheard of phenomenon, in which a living entity was completely nonexistent in The Force.
The earliest known account of this event, in 27 BBY, was Granta Omega, the son of the Dark Jedi Xanatos, who was described as a "void" in the Force by Obi-Wan Kenobi, who himself could only speculate Omega was utilizing some form of self-concealment technique. Peculiarly, Omega's ability allowed him to escape detection by the Jedi, and also rendered him extraordinarily difficult to remember. Even in the event someone did recall him, they would not be able to place his appearance.
Another incident of this marvel was identified in 0 ABY, concerning the Human clone assassin X-7. As noted by Jedi Knight Ferus Olin, X-7 was noted as having a hollowed body, with the Force flowing around him, rather than through him. This was the first and only known incident of such a phenomenon occurring artificially.
Perhaps the most outstanding cases were those of the assassin Umbaran siblings, Nyss and Syll Nenn. Both siblings displayed the ability to create a dark void in the force, making them undetectable to Force sense. Further still, the Nenn twins could also make the Force inaccessible to Force-sensitives (though Jaden Korr and his clones were somewhat resistant to this for unknown reasons). Indeed, this power was potent to the degree that they were capable of nullifying the force energy present in lightsaber crystals, causing them to shut off completely. After the death of Syll, Nyss Nenn felt that his ability had increased, when while his sister was alive, he had always psychologically thought that she was an amplifier.
