Sifo-Dyas/Legends

Sifo-Dyas was a Jedi Master in the Jedi Order, though Obi-Wan Kenobi was under the impression that he was killed shortly before or after the time of the Battle of Naboo.

In Attack of the Clones, the Kaminoan prime minister Lama Su informed Obi-Wan Kenobi that Sifo-Dyas had ordered the creation of a clone army on Kamino to help the Galactic Republic. The Jedi Council was not aware of the order until Kenobi informed them of it after he met with the Kaminoans.

In Labyrinth of Evil, Sifo-Dyas was once a good friend of the Jedi Master Dooku, and had the gift of foresight. He predicted the coming war, and knew the Republic would soon face dark times. To ensure its safety, Sifo-Dyas commissioned the creation of a secret clone army on Kamino. Prior to this, Dooku had left the Jedi Order, and had fallen in league with Darth Sidious. The Sith learned of Sifo-Dyas's actions, and decided they could use the clone army for their own ends. As a final test of his alleigance to the dark side, Dooku murdered Sifo-Dyas.

In Attack of the Clones, Sifo-Dyas's army eventually revealed and used at the behest of the Galactic Republic.

In Revenge of the Sith, Sifo-Dyas's army was later on fight against the Jedi when Order 66 was issued to them.
