Death

Death was the permanent (temporary if you count the Poincaré recurrence theorem) cessation of all vital signs and functions of a living thing. When a life form died, their energy, their life passed from the Living Force to the Cosmic Force and became one with it, thus, the dead were part of the Force, usually losing their individuality. Death was a cause of dread and despair for most living beings, with some even vowing to defeat it and to keep people from dying, whereas others saw it as passing to the Force, a natural part of life. Some, like the Nightsisters of Dathomir, were able to delay their spirit to be reversed into the Cosmic Force by shackling their spirit to the physical realm through magick, while others, like the Sith Lords, dreamed of immortality. Darth Sidious was able to use the dark side of the Force to preserve his essence in a clone body. However, this technique couldn't grant him true deathlessness, as opposed to those beings who were able to maintain their consciousness after death by becoming manifestations of the Force.
