Galactic Empire - Imperial star fleet

During the Battle of Endor between the Galactic Empire and the Alliance to Restore the Republic, the Dark Lord of the Sith Darth Vader and his son, Luke Skywalker, faced one another in a final lightsaber duel aboard the second Death Star, a space station capable of destroying an entire planet. Luke defeated his father and proclaimed himself a Jedi Knight but was attacked by the Emperor, Darth Sidious, who used Force lightning in an attempt to kill Luke. Refusing to watch his son die, Vader—who still had good within him—threw his Master down a reactor shaft. This act redeemed Vader from the dark side of the Force, and he once again became Anakin Skywalker.[1] With Sidious dead, the Sith were defeated.[3]

The choice to save Luke was ultimately a sacrifice, as Sidious' lightning struck Anakin when the redeemed Jedi threw the Emperor down the shaft. Anakin's redemption and Sidious' death brought balance to the Force, and Anakin fulfilled his destiny as the Chosen One.[4] Luke attempted to save Anakin by bringing him to a shuttle, where they could escape the Death Star, but Anakin knew that his death was imminent. At his father's request, Luke removed Darth Vader's helmet from Anakin's head, allowing the former Sith Lord to look upon his son with his own eyes for the first and last time. In his final moments, Anakin comforted Luke, reminding his son that there was always good in him—just as Luke had believed. Anakin passed away,[1] and his body disappeared as he became one with the Force.[5]
