In the dream world, Lucina entered a room where she sees a chest in the middle of the room. She stepped up to it and slowly opened it to find a lightsaber hilt inside. She reaches for it very slowly without hesitation. As she grabs it, the ignition sound of the lightsaber was heard and she moves her hilt away as she heard mechanical breathing echoing as the room began to change into a hallway where Charming Thunder faced King Sombra for the first time. Voices of Sombra, Chrysalis, and Celestia echoed as Lucina runs down the corridor. The room tilts and change as she tripped and fell on the floor of the castle she is currently in. She looked up to see a hooded pony making a droid which looks like BB-8 while Charming Thunder's scream echoed. The room then started to rain as she turned around to see Equestrian soldiers getting killed by Twivine's lightsaber in a nighttime environment. Lucina was frightened as she looked around to see corpses lying on the floor. She shuts her eyes and opens them again to see that she is standing in a hallway of a ship. She runs through the hallway when suddenly, Twivine emerging from the corner with her trident lightsaber active. Lucina screamed and falls back and the room changed into the crystal heart under the castle of the Crystal Empire. She turned to see a pony who looked a lot like her cousin; Flurry Heart grown up running out of the door past the crystal heart until a light shone in front of her. Lucina hid so that she wouldn't get caught as well. Flurry looked up to see a TIE Advanced X1 slowly landing to the ground with an armored figure that looked similar to the one Lucina saw at the museum on top of the fighter with his lightsaber active. The armored pony leaps off of his ship as it was about to touch down. Flurry jumped out of the way and activated her lightsaber. "You have unlocked the secret of the kingdom," the pony said. "How did you accomplish this?"
"You're smart," Flurry replied. "You figure it out." Flurry swung a strike at the pony, but he blocked the strikes and pushed her forward. Lucina watched as the duel started.
"No matter. The power within will soon serve me."
"I am not afraid of you."
"Then you will die just like your mother and father." The pony gave a few strikes as the duel continued. They then clashed their blades together and the pony pushed Flurry back destroying her lightsaber in the process. Flurry crawled away from him with fear as he approached. "Perhaps I was wrong." He raised his lightsaber and readied the killing blow.
"Leave her alone," Lucina shouted as she came out of hiding. The armored pony turned to face her as Flurry saw her walk out.
"I was beginning to wonder when you would be here. Our long-awaited meeting has come at last."
"I hope that was something to look forward to." The pony deactivated his lightsaber and took a step forward.
"We need not be adversaries. I will show you mercy if you tell me where Celestia can be found."
"I would not let give you that information and let you kill Celestia." The pony turned to look at Flurry who was still crawling.
"Perhaps the daughter of Cadence and Shining Armor will confess something you would not."
"I was beginning to believe I knew who you were behind that mask, but it's impossible. My father would never be as vile as you." The pony turned his gaze back to Lucina.
"Charming Thunder was weak. I destroyed him." Lucina closed her eyes and sighed.
"Then I will avenge his death."
"Revenge may not be the Jedi way, but you are no Jedi." The pony activated his lightsaber as Lucina drew her sword and got into his battle position. Lucina charged at him and was the first to strike. The pony blocked her strikes as he backed up. He tried to strike, but Lucina ducked and blasted him with her unicorn magic. The pony looked up to see her coming towards him in the air and blocked the incoming strike. They then clashed their blades and took their duel away from the crystal heart. They soon arrived inside the castle clashing blades. They destroyed objects in their surroundings in the process during the duel. Lucina held her ground as she clashed her blade together. The pony broke the clash and force pushed her out of the window safely landing on the ground unconscious. He then leaps out of the window and walks to the crystal heart where Flurry was trying to flee. Lucina soon regained consciousness as he walked past her. He used the force to lift Flurry in the air and slam her to the ground.
"No!" Flurry shouted as she tried to break free. "No, no, no, no, no, no, no, no, no!" Lucina got up and dashed towards the action. The pony turned to see her heading his way. Lucina jumped in the air and slashed him in the face and fell to the ground at the other side of him.
Lucina slowly got up and grabbed her sword when the pony said, "Lucina!" She had a shocked expression and turned to wonder how he knows her name. Breathing sound was different as he slowly got up. He turned to face her to reveal his exposed eye. "Lucina." She recognized the coat color and was shocked.
"Father," Lucina said as she got up. Charming Thunder got up as Lucina sheathed her sword. "I am not killing you. Not my own father." He breathed heavily as he looked away from Lucina. He then looked back at her to reveal his eye color turned orange.
"Then you will die!!" Charming Thunder activated his lightsaber and walked up to her, but was stopped when he began to glow. "NOOOOOOO!!!" He then disappeared and the room changed once again to a starry sky. Princess Luna appeared and walked up to her.
"Calm yourself, Lucina," Luna said. "It was just a nightmare you had."
"What was all that I just witnessed?"
"What you have seen was memories of the time before your father vanished three years ago."
"You mean the Charming Thunder I faced....was his dark side?"
"Correct. And I take it that you saw Twivine?"
"Who's Twivine? To me she looked a lot like my mother, but darker."
"She is the princess of the plunder seeds. Your father once faced him along with his brother and succeeded. Before she vanished, she asked Charming Thunder if the next time she would ever returned, he would reform her. But now things change."
"What do you mean, Aunt Luna?"
"With Charming missing for three years, he would not help now. That was when I had a vision of a mare would defeat Twivine and reform her. And that mare was you, Lucina."
"Me? How am I supposed to reform her? I have seen what she is capable of."
"The lightsaber you have seen was your fathers and it calls to you."
"Twilight held on to it ever since Charming Thunder switched to his cross guard lightsaber. Take it and reform Twivine. For it is your destiny." The room began to flash white as Luna flew away from Lucina.
---------------------
Lucina woke up in the morning and jumped out of bed after knowing what she has to do. She noticed Twilight enter as she fixed her mane. "Bad dream?" Twilight asked.
"More than like a nightmare," Lucina replied. "Hey, mom. Do you have my father's first lightsaber."
"Why do you ask?"
"You wouldn't believe me if I told you." Lucina then began to explain Twilight about what Luna revealed to her in the dream world.
