3rd Pov

Months after the destruction of the first world, Y/n was training Salem turning her into the Sith. Y/n gave her knowledge of the Sith and how they are enemies of the Jedi. Salem did not realize she had the force since she was born. Y/n gave her new power which she will break her chains and become who she is. Salem created her lightsaber thanks to
Y/n's spare lightsaber parts and a crystal which he took from his master. Y/n wanted his apprentice and train him the sith. Y/n knows she will betray him and he wanted to test himself of becoming immortal. For days the training of becoming sith was faster than he ever expect. His new apprentice learned everything she had, Y/n feels the power of the Darkside in her and she would later kill him.

Hours later

Somewhere in the Grimm pool, Y/n was with Salem who is wondering about the source of a new Darkside power.

Y/n may have a new source of Darkside power. He closes his eyes as he senses the power in it, all the negative energy. Salem later had the chance to kill his old master knowing she knows the Darkside. Salem ignited his lightsaber and strikes him. Y/n dodges and uses his force lighting hitting her. Salem screams as he later falls down the Grimm pool. Y/n did not walk away knowing that she is immortal so she will come back. Y/n watches as she comes back with a different appearance.

Salem jumps up as she uses the force. Salem strikes at Y/n while he gets out his lightsaber and deflects her attack. The two clash with each other knowing that the victor will be the master. Salem was trained by him and she has her magic and force. Y/n has the god's power but he wanted to test her and himself. Salem uses all of her rage and power she has. Salem was taking advantage of her power over the Darkside. Salem stabbed Y/n and he disappear, what was left was his clothing and his lightsabers. Salem later sees a dark shadow that disappears out of existence. Y/n who is the great shadow has achieved his mortality. With great power, he later waited until his opportunity to create his own Sith warriors. For years the god of light created humans and a new race called the Faunus. Y/n later insert the force to make them force-sensitive. Y/n would not know if this would work but if it did work then he will have his Sith army outmatch the Jedi.

Timeskip many years later

Y/n in his dark entity form was watching the world change. Y/n later learns that Salem's husband Ozma was sent back by the Light God. Y/n knows that the Light God wants to make sure that the man who stole the power is gone or tries to kill him. Y/n lurks in the shadows and he witnesses new life. Y/n watches as Salem has four girls and he senses new power. Y/n had his idea that he will come back and later punish Salem for her betrayal and later train her and her children. Y/n later watches to learn more and find her weak spot so she will join him. Y/n watches as he later sees Ozma taking four of his children. This a foolish move that will make Salem angry, Salem later sees Ozma taking her children which causes her to attack him. The two fought and destroyed the whole tower. Y/n looks around as all her children are gone, Y/n smiles under the shadows to see that Salem will do everything. As Salem killed her husband in cold blood, he later appears under a dark cloak. Salem looks behind to see his master alive. Her eyes widen as he senses fear in her.

Salem: "Maa-Master!!!"

Y/n: "Yes Salem. I have returned."

Salem: "Yes and I am surprised that you killed your husband in cold blood."

Salem: "Master how is this possible?! I stabbed you."

Y/n: "Yes and it kinda tickles. I have finally achieved immortality thanks to you. And....I have something for you."

Y/n shocks her with force lighting. Salem screams in pain as she never felt pain as an immortal woman. Salem was screaming very loud and Y/n loves to hear her pain. Y/n stops as Salem was on her knees. He put her in his place but he does not want to kill her since he found a perfect apprentice and a goal that she would have or never have.

Salem: "Please....kill me....end my suffering...."

Y/n: "....Salem....You see me achieve immortality and now I will achieve something that no one will have. *Uses the force and grabs a dog toy* To achieve those who can be revived from death."

Y/n gives Salem the dog toy which she gets up and held. Salem looks at him as if she knows that he was right. If he achieves becoming immortal and can able to hurt her then he would achieve those who can be revived from death. Salem kneels as she later becomes the apprentice of Y/n. Y/n laughs as he now has the plan to get revenge on the Jedi and rebuild his new Sith Order under his vision. The planet will later witness the Sith's plan to dominate and kill anyone who dares to oppose his plan.
