Backstory:

Obi-Wan Kenobi was a legendary Force-sensitive human male Jedi Master who served on the Jedi High Council during the final years of the Republic Era. As a High Jedi General, Kenobi served in the Grand Army of the Republic that fought against the Separatist Droid Army during the Clone Wars, and was nicknamed "the Negotiator." Kenobi, however, was forced into exile as a result of the Great Jedi Purge initiated by the Republic's own clone troopers when Republic Supreme Chancellor, secretly Darth Sidious, implemented Order 66. As a mentor, Kenobi was responsible for training two members of the Skywalker family, Anakin and Luke Skywalker, both of whom served in turn as his Padawan in the ways of the Force.

Kenobi was born on the planet Stewjon in 57 BBY. He was Force-sensitive, and therefore taken from his family and inducted into the Jedi Order as a child. Raised in the Jedi Grand Temple on the planet Coruscant, Kenobi was assigned to Jedi Master Qui-Gon Jinn. In 32 BBY, Kenobi attained the rank of Jedi Knight by defeating the Sith Lord Darth Maul during the Invasion of Naboo. He also chose to train Anakin Skywalker—the prophesied Chosen One who was destined to destroy the Sith and restore balance to the Force—having promised Jinn who died in the lightsaber duel against Maul.

With the advent of the Clone Wars in 22 BBY, Kenobi adopted the military rank of High Jedi General in the Grand Army of the Galactic Republic, and was given command of the Open Circle Fleet, the Third Systems Army, and the 7th Sky Corps. Clone Marshal Commander Cody served as his second-in-command throughout the galaxy-wide conflict, with their forces achieving multiple victories over the Confederacy of Independent Systems. In the midst of the war, his old enemy Maul re-emerged into galactic affairs, bent on revenge against Kenobi for his debilitating defeat decades prior. Though they clashed in heated duels on multiple occasions, Maul failed to end Kenobi's life or cripple his spirit, despite murdering his former love, Satine Kryze, Duchess of Mandalore.

In 19 BBY, Kenobi killed the Separatist Supreme Martial Commander, General Grievous, during the Battle of Utapau, effectively ending the Clone Wars. He later survived the initial onslaught of the Great Jedi Purge against the Jedi Order, which resulted from the machinations of the Sith Lord Darth Sidious. After discovering that Skywalker had turned to the dark side of the Force, becoming Sidious' Sith apprentice under the name of Darth Vader, Kenobi defeated his former Padawan on Mustafar and exiled himself to the Outer Rim planet Tatooine as the Galactic Empire rose to power.

When We See Him (Through Vader’s Eyes):

Experiencing second thoughts about his journey to the dark side, Vader reassembles the lightsaber. He experiences a vision where he returns to the Emperor on Coruscant with the green lightsaber. Realizing that Vader has not embraced the dark side, he attacks the Sith apprentice. Vader defeats him in a duel and then travels to find his former Master Obi-Wan Kenobi. Seeking to atone for its wrongs, Vader bows before Kenobi who raises his lightsaber to strike him down. However, Kenobi experiences second thoughts and deactivates his lightsaber, calling Vader by his former name Anakin.

Awakening from the vision, Vader believes there is no turning back from the Sith path and uses the dark side to bend the kyber crystal to his will. As he pours his anger and hatred into the crystal, he experiences visions of the past including Kenobi, his late mother Shmi Skywalker Lars, Padmé Amidala and the Emperor. The dark side also triggers a lava explosion nearby.
