Qui-Gon Jinn's Master was
Sifo-Dyas was one of the few Jedi in the history of the order with the ability of Foresight. Meaning he could clearly see future events. He was also a close friend to his eventual murderer, Count Dooku. Master Sifo-Dyas was born on Minashee in 102 BBY as the son of a fisherman.
While Dooku was certainly evil -- and even had a Darth sobriquet, Tyranus, that he rarely used -- he was never quite a Sith, at least not in the true sense. Unlike those who espoused the Sith doctrine, Dooku wasn't motivated by hatred or fear, but by the same purpose that drove him as a Jedi.
Over the next decade, the galaxy was on the verge of civil war with entire star systems—led by Count Dooku, Yoda's one-time Padawan—threatening to secede from the Republic by 22 BBY.
The story centers on Jedi Master Mace Windu as he attempts to rescue his former Padawan, Depa Billaba, from his homeworld, Haruun Kal.
Padawan Windu was trained in the ways of the Force by Jedi Master Cyslin Myr.
Palpatine, pretending to be a helpless bystander, goads his future apprentice on. “Do it!” he hisses. Skywalker does, beheading Dooku as he gives in to his base emotions. He almost immediately feels regret, but Palpatine works to dismiss it.
The reason Dooku joined the Separatists, he said, was that he learned a terrible truth: a Sith Lord called Darth Sidious controlled the Senate. With Obi-Wan at his side, they could destroy the Sith.
Count Dooku became a Sith because the Jedi served a corrupt Republic, but he had another more personal reason to betray the order. The following contains spoilers from Yoda #4, on sale now from Marvel Comics. Darth Sidious was Star Wars' master schemer.
A member of the Jedi Council before the blockade of Naboo, Sifo-Dyas believed the galaxy would soon be plunged into war, and agitated for the Republic to create an army for its defense.
According to Star Wars Legends content, the first Sith was a former Jedi Master, Ajunta Pall, who became a so-called Dark Jedi, or “Fallen” Jedi.
The Prime Jedi was an individual who became the first Jedi to ever use the Force. The Prime Jedi was also the founder of the Jedi Order. The Prime Jedi established the Order on the planet Ahch-To, around 25,025 BBY.
Sidious, born Sheev Palpatine, was trained in the dark side of the Force by Darth Plagueis.
Palpatine rules the galaxy for over two decades before Vader betrays and kills him to save his son, Luke Skywalker.
At one time, Dooku was the Padawan of Yoda, the Grand Master of the Jedi Order. In 86 BBY, Dooku later completed his Initiate Trials and hoped to be selected as the Padawan apprentice to Lene Kostana due to her mission in hunting down relics associated with the dark side.
In Anakin's case, it was his background (son of a slave raised in poverty) and his prosthesis what made in inferior in Dooku's eyes.
While Dooku was certainly evil -- and even had a Darth sobriquet, Tyranus, that he rarely used -- he was never quite a Sith, at least not in the true sense. Unlike those who espoused the Sith doctrine, Dooku wasn't motivated by hatred or fear, but by the same purpose that drove him as a Jedi.
Sidious may have given Dooku the title of Darth Tyranus, but because the Jedi Order knew him as Count Dooku, greatly preferring to not indulge his role as a Sith, they continued to call him by that name.
It's not shown, but it is clearly insinuated that Anakin killed the younglings. This is confirmed later in the movie when Obi-Wan informs Padme that Anakin killed them. Both are torn apart with hurt and confusion, trying to make sense of something so terrible. How could Anakin do such a thing?
In Star Wars canon, there are currently only four younglings that are known to have survived the infamous Order 66 and Darth Vader's slaughter, while in Legends, there are 20 known survivors.
The Younglings Reminded Anakin of How Different He Was
Those negative emotions also power the dark side, meaning Anakin likely felt stronger as he killed the younglings. That, in turn, reinforced his belief that only the dark side could save Padmé.
Within the Star Wars Legends continuity, Yoda's Jedi instructor was N'Kata Del Gormo, a Hysalrian Jedi Master, according to an in-universe legend.
In 19 BBY, the lightsaber was lost when it was dropped out of the window of Supreme Chancellor Palpatine's office prior to his death. In 18 BBY, Duros salvagers recovered it and gave it to Senator Sano Sauro.
