Shadow Hand

Shadow Hand was the title given to the second-in-command of the Sith monarch, or Sith'ari.

Later, members of the Sith Order would use it as both a title for the second-in-command of the Sith Master and as a term equivalent to an apprentice.

The Shadow Hand of King Adas would inherit the fallen king's holocron; while another Shadow Hand of King Hakagram Graush, many thousands of years later, betrayed his master to the newly arrived Dark Jedi, thus paving the way for the first of the Dark Lords of the Sith. After Hakagram Graush's death, Pall appointed his fellow Dark Jedi as his new Shadow Hands.

During the Krath Holy Crusade, the spirit of long-dead Dark Lord of the Sith Marka Ragnos branded Ulic Qel-Droma with the mark of a Shadow Hand, whom Ragnos said would become Exar Kun's first and foremost apprentice. During the Jedi Civil War, after disposing of his master, Darth Malak made Darth Bandon both his apprentice and Shadow Hand. A few years later, during the Dark Wars, Visas Marr served as Darth Nihilus's Shadow Hand after she was retrieved from the surface of her destroyed homeworld Katarr. The concept continued with later Sith. Darth Vader trained his own disciples, among them Lumiya and Flint, in the hopes of pitting them against one another to find a champion worthy of being the Dark Lord's own Shadow Hand. Prior to this, Darth Cognus, who, like Vader, was a Sith of the lineage of Darth Bane, trained her apprentice Darth Millennial as a Shadow Hand.

Darth Bane's Rule of Two had a Sith master as the Dark Lord of the Sith, while the aprentice servered and his/her Shadow Hand until they killed their masters to become the new Dark Lord and take their own apprentice to be their own Shadow hand.

The reborn Darth Sidious used the name for his campaign to retake the galaxy.
