Death

"Death is a natural part of life. Rejoice for those around you who transform into the Force."

- Yoda

Death was the cessation of life functions in biological organisms, permanently rendering it unresponsive to any external factors. Once a life ended, its spirit would ascended to a different plane of existence and become one with the cosmic Force; however, some Jedi were able to maintain their conscious individuality beyond death by learning the secrets of the Living Force. Certain individuals who were not followers of the Jedi teachings often referred to the different plane where the dead reside as the "other side." Many individuals also sought a way to forestall death or even avoid it entirely.

Darth Plagueis was a Dark Lord of the Sith whose knowledge of the midi-chlorians was said to be such that he had the ability to keep those he cared about from dying. Anakin Skywalker, desperately seeking a way to prevent what he had seen come to pass in his vision of the death of Padmé Amidala, was entranced when Darth Sidious told him a tale of this.

The Nightsisters of Dathomir kept their dead close by, suspended in pods near their village, so that no sister ever truly left the clan. They believed that the dead could share in the emotions of the living, and with a magical chant could temporarily be reanimated in the form of undead warriors, which was called into combat during the Battle of Dathomir, but they were ultimately destroyed by Grievous.

When the body of the last Nightsister, Asajj Ventress was laid to rest in the pools of the village, green mist arose as the voices of her sisters welcomed her home. After death, the spirits of the Nightsisters were tethered to the altar in the Nightsister lair. They were awakened by Ezra Bridger and Maul. Two Nightsister spirits possessed two of Ezra's friends, Sabine Wren and Kanan Jarrus, in an effort to return to the physical world and rebuild their clan, but he destroyed the altar and consequently the spirits dissipated.

Besides combat-related deaths such as the Force, lightsaber strikes and blaster fire, other causes of death could include dehydration, starvation, untreated or untreatable physical damage to the body, exposure to certain chemical substances, and certain diseases.

Although dying while on Mortis, Ahsoka Tano was revived back to life by the Daughter, who transferred her life form to Tano after being stabbed by the Son.

The Death Star was named after the concept of death, as well as the highly specialized Death trooper.

Project Blackwing sought to find a way to conquer death, but instead created a virus that would kill and then reanimate those it infected. The stormtroopers infected were referred to as Undead Troopers.

The death of Han Solo left his son, Kylo Ren, conflicted with his choice of the dark side of the Force, as he initially thought killing his father would relieve him of any emotional hindrance.

Luke Skywalker's death resulted in the disappearance of his physical body as he became one with the Force.
