Serenity's eyes snapped open as the killing curse engulfed them, but nothing happened. The green light swirled around them as if a sphere of protection blocked the two from harm. She would have put more thought into it, but other things clouded her mind. Images flashed before her. Men and woman all possessing what people called the 'dark mark' on their wrists. Names flooding into her mind, as well as memories from when she was a child. Being passed from one death eater to another, none of them telling her why she couldn't just stay with her father. Then:

-Flashback-

"The ministry of magic is becoming suspicious. I can't have her in my house any longer!" A male voice boomed. Many men and women sat together, Serenity knowing almost all of them. They were her father's followers, or at least they were.

"Well we can't take her to our homes. That would be asking to be sent to Azkaban." Another voice reasoned.

"Do we dispose of her then?" Hushed whispers began, thinking the idea over.

"No, if the dark lord should ever return . . . It would cost us our lives. I have a better idea." The blond haired man smiled and looked over to the door. "Serenity, dear, come here. I know you're there. Come on out." Lucius called to the small six-year-old Serenity. She nodded and walked towards him, her eyes on her feet.

"Yes Uncle Lucius?" She asked quietly as she brushed the small silver curls away from her face. Lucius directed his wand at her.

"Obliviate!" He said, and all went black.

-End flashback-

She frowned and her grip on Serverus' hand tightened. Thoughts of her dream; of the moon kingdom and her friends all dying now pushed their way into her mind. Then with a flash of white all the looming green energy vanished. The wound on Snape's chest healed, and all of Serenity's wounds did the same. She closed her eyes for a moment as she felt a new power overwhelm her. Her sailor fuku grew into a long, white princess' gown, and with a quick squeeze of Snape's hand Endymion's armor appeared on him. Her love of long ago wore this. The one she loved now will take his place, and the armor would protect him.

Her eyes fluttered open, and her father grew near once more with an even larger army. Every dark creature imaginable was following behind him, as well as creatures that were simply tempted to the dark side like the giants and other death eaters. The professors and aurors (sp?) walked out of the school, as well as seventh year students, D.A. members, and of course Harry, Ron, and Hermione.

Everyone stopped and stared at Serenity and Snape in awe. Snape had awakened, and the couple stood side by side. Serenity's back arched, and Snape supported her so she didn't fall backwards. A small flower shaped crystal emerged from her chest, and she held it between her hands. The pure white energy protected all those who followed Dumbledore as well as her father. Instantly afterwards the 'war' began, lasting for a fair amount of time until all of Voldemort's followers were gone. Voldemort stepped towards his daughter, Serenity stopping anyone else from coming near.

"Voldemort.." She said softly. A thin, pale hand rose to her cheek, and Voldemort smiled.

"Serenity, my daughter, why do this to me? Why betray me?" The white aura that covered Voldemort glowed brightly. Slowly it died away and Tom Riddle stood before Serenity, looking as he did in her only memory of her father from so long ago.

"Father, I can't ask you to understand all of this because it is much more complicated then you think, but know that it is not your daughter who betrays you but instead the princess of the moon. I stand for truth and justice, and because of this I must put a stop to your wrong doings. I love you, my father, but I must stop you" As she finished Snape took hold of Tom's hand, and Serenity ushered Harry forward. Harry raised his wand instantly.

"Cru-" He began, ready to make Voldemort pay for murdering his parents, killing so many others, for causing him so much grief, and for taking Sirius away from him.

"Harry wait. Don't do that. Just kill him and be done with it." Serenity pleaded, moving behind Harry and resting her hand on top of his. Tom stood watching his only daughter, his heir, telling his enemy to kill him. Though normally he would fight, he would not harm his daughter, not again. He freed himself from Snape's grip, and turned to look at one of his former death eaters whilst Potter argued with Serenity.

"If you hurt my daughter you will pay. I will get revenge from beyond the grave if I must. Do not betray her as you did me." He said, his voice dripping with malice. Snape only nodded, in shock slightly. Here he stood talking civilly with the darkest wizard of all time.

Tom turned to see a green light moving at Serenity and Harry from behind. Voldemort pushed his daughter aside and glared at the death eater. He dropped to his knees in pain, but still killed the death eater who dared attack his daughter for the second time. Then he saw Dumbledore staring at him, a look of triumph on his face, and he had to kill the old man who had plagued him for so long.

He pushed himself to his feet and started towards the old man. Both of them raised their wands, and bowed as if dueling. Curses of all sorts flew between them, but when Voldemort yelled Crucio he was surprised to have found his daughter take the blow for the headmaster. He stared in shock as Serenity writhed in pain on the ground, and then he laughed. He envisioned his wife of long ago in his daughters place, and he laughed at her like he had never done before. The woman who defied him and tried to take his daughter away, who turned against him and went to Dumbledore, the woman he killed.

"She deserved to die." He muttered as he yelled the curse again and again, madness evident in his eyes as he took pleasure in hearing Serenity scream. Snape and Dumbledore were doing all they could to stop Voldemort, and Harry trying to find an opening so he could kill the bastard, but neither of them succeeded.

"Pluto Deadly Scream!" (AN: I think that's right. I'm not quiet sure.) Voldemort as well as Dumbledore and Snape fell to the ground beside each other. A woman stepped forward and pulled Serenity, who had stopped screaming, to her feet.

"Hime. This must end." Serenity shot the woman a confused glance, but nodded. She pulled Harry towards her father.

"Finish it Harry." She said softly. Harry pointed his wand and said the killing curse without hesitation. Voldemort shrieked in pain and was reduced to a spirit like form, where he then appeared to have exploded. Ashes blew around the area, and Serenity caught on in her hand. Instantly the ashes became rose petals, and everyone watched as their enemy of so long was destroyed by two teenagers.

Snape came up behind Serenity and held her close. Dumbledore sent them an odd glance, but then laughed. He moved in front of the couple and wished them happiness, after apologizing for misjudging Serenity and thanking her. He then turned and led the students inside the castle. Soon everything was quiet and Serenity turned to look at Snape.

"I love you." He said gently and kissed her. He had been denying himself this for so long, and now that he had her . . . He would never let go.

ARG! I soooo hate this chapter. I hope you liked it more then I did. I was deciding whether or not to make this a sad ending where Voldemort killed his daughter right before he died or something, but . . .Well. I didn't. So yeah. And Pluto made a moments appearance. XD Well 'I can't let go' is officially finished! Now to start a new story. MUHAHA! BEWARE!
