Rey: "Purification?" Serenity: "Remember how Sidious continued to live on even after Anakin destroyed his body. How he used you and Ben to restore his present decaying form." Rey: "Yes, like he was sucking the life out of us." Serenity: "He has used the same technique as the first Sith emperor, Tenebrae, used to continue after death." She shows Rey through another door Tenebrae's story. Serenity: "He was the lesser son of a Sith lord who used the dark side to drain the life energy from all living things on his home planet. But he also cursed himself in the process to a perpetual decaying body. Then he learned how he could transfer his essence and infuse his soul into the bodies of other people, making them the Children of the Emperor. This is how he lived for so long like Sidious. By transferring his soul from body to body. His last body was that of the Emperor Valkorion of the Zackul Empire, and he used its resources to destroy both the Republic and the Sith Empire. When that body was destroyed, he inhabited the body of the leader of the galactic alliance and sought to use it to accomplish his ultimate goal of using the reeve ritual on the entire galaxy to make himself an immortal possessing absolute power. However, the Force used his family, his pride, and the one he saw as a means to ultimate power only to be defeated and expelled. Only for his soul to return to his original body which was a lifeless corpse in a tomb to await an unfortunate person to become its new vessel. But a short time later a former child of the emperor, Kira Carsen, and his former personal enforcer or wrath turned friend of the Jedi, Lord Scourge, found and destroyed Tenebrae's body. With that, his soul no longer had any way to remain in the material realm and so his reign of terror was brought to a permanent end. Others who have used the electric judgement used it in the same way. By letting the will of the Force be done through them, the essence and souls of evil force users are forever severed from the mortal plane. Even if you manage to destroy Sidious' body. He can easily jump into a clone or someone willing to be the vessel for his soul, as he tempted you to do." Rey: "So you're telling me that the only way to end his presence and reign forever is to use the electric judgement to purge his essence from everything he has infused it into." Serenity: "Not only him. He is now also the conduit for the souls of all the Sith as well as the souls of all evil Force users across the universe. He has bound them all to himself." Rey: "Severing his connection to the material plane will sever theirs as well." Yoda: "Thus the prophecy of the Sith being destroyed and the balance in the Force will be." Showing her his past after he returned from Malecore on his journey of discovery at the behest of Serenity. Rey stands next to Yoda watching himself in the Jedi Temple courtyard on Corusant. Yoda as speaks to masters Windu and Kenobi, "No longer certain that one ever truly wins a war I am. For in fighting the battles the bloodshed, already lost we have. Yet open to us a path remains. That unknown to the Sith is. Through this path victory we may yet find. Not victory in the clone wars, but a victory for all time." Back in The World between The Worlds Yoda turns to Rey to say, "That victory at hand now is. We are what you beyond must now grow." Rey then asks a general question to everyone, "Does everyone, even those not able to use force abilities, live on after death?" Anakin: "The simple answer to that Rey is, we can't tell you. Not that we choose not to, it's that we genially can't." Luke: "For death is meant to be the ultimate mystery along with how life began." Leia: "That unknowing is meant to give you a reason to treasure every moment you live and to encourage you work to leave a good legacy for future generations to follow." Qui Gon: "You must learn to enjoy the mystery and take a leap of faith into the unknown. For in the end that's all living for now and tomorrow comes down to." Rey: "Steps and leaps of faith."
