Darth Bane was a legendary human male Dark Lord of the Sith and the sole survivor of the destruction of the Sith at the hands of the Jedi Order during the Jedi–Sith war a thousand years before the Clone Wars. As the only surviving Sith, Bane recognized that Sith infighting had weakened them to the point that the Jedi could destroy them. To rectify this, Bane reformed the Sith and created the Rule of Two, mandating that there could be only two Sith—a Master and an apprentice—at any given time. These new Sith would begin a plot to destroy the Jedi in secret. With Bane's defeat, the Jedi wrongly believed that the Sith were defeated with him
The vendetta Bane held against the Jedi was fulfilled during the Clone Wars, when Supreme Chancellor Palpatine, secretly the Sith Lord Darth Sidious and a follower of the Rule of Two, transformed the Galactic Republic into the Galactic Empire and destroyed the Jedi Order. However, the victory was short-lived, as the redeemed Jedi Knight Anakin Skywalker, formerly the Sith Lord Darth Vader, defeated the Sith twenty-three years later
Anakin Skywalker was a Force-sensitive Human male who served the Galactic Republic as a Jedi Knight and later served the Galactic Empire as the Sith Lord Darth Vader. Born to the slave Shmi Skywalker in 41.9 BBY, Anakin was conceived by midi-chlorians, the symbiotic organisms that allowed individuals to touch the Force, and he and his mother were brought to the desert planet of Tatooine to be the slaves of Gardulla the Hutt. They soon ended up as the property of the Toydarian Watto, and Skywalker exhibited exceptional piloting skills and a reputation for being able to build and repair anything even at a young age. In 32 BBY, Skywalker encountered the Jedi Qui-Gon Jinn and Padmé Amidala, and he helped them secure the parts they needed for their starship by winning the Boonta Eve Classic podracing event—only to learn that he had also won his freedom in doing so.
Revan—renowned as the Revanchist, reviled as Revan the Butcher, worshiped as the Revan, dreaded as the Dark Lord of the Sith Darth Revan, and praised as the Prodigal Knight—was a human male who played pivotal roles as both Jedi and Sith in the Mandalorian Wars, Jedi Civil War, and Great Galactic War.
Believed to have been born around 3994 BBY in the Outer Rim Territories, the child later known as Revan was found by the Jedi Order and apprenticed to the Jedi Master Kreia. The Padawan had an insatiable hunger for knowledge and soon became the Jedi’s most promising pupil. Alongside his friend Malak, he became a Jedi Knight and a vocal and charismatic critic of the Order's inactivity in the ongoing Mandalorian Wars between the Galactic Republic and the Mandalorian Neo-Crusaders. In defiance of the Jedi Council, the Knight took upon the name Revan and started the Revanchist movement to combat the Mandalorians as the Republic Military's Supreme Commander. Revan and his forces gradually pushed back the Mandalorians, saving countless worlds at the price of devastating moral compromises and the embrace of dark side practices. On Malachor V, Revan defeated the Mandalorian leader Mandalore the Ultimate in single-combat and ordered the activation of the Mass Shadow Generator superweapon, destroying both armies and the planet but winning the war in the process.
