In the great hall, students and professors was apprehensive, in a coming battle, as a group of armor knights Apparated away, and once they were gone, Dumbledore turned to those who had assembled. "You all know the drill, we have been practicing, and Ron, Hermione, make sure my god-daughter is safe," they nodded as they headed to the door, but were stopped, as a large round reddish mist appeared. "What is that?" Hermione asked. "Everyone back away from it now!" Dumbledore yelled, but a second later, a girl of fifteen stepped through, and looked about as the mist disappeared.

For a while no one spoke, till the girl looked to the professors. "Great I'm not home yet!" she said, looking tired. "Excuse me, who are you?" Dumbledore asked, his wand was drawn, as well as others the second the girl appeared. "My name is Alexandra Potter, I'm from another reality, and I'm trying to find my way home," Alex said, as she sat down. "Everyone, head out to your assigned posts, I will have a word with Alexandra." Dumbledore said, as everyone headed out, but they were as weary as Alex.

Once the great hall was cleared, Dumbledore went to Alex. "Alexandra-" Dumbledore started, but Alex stopped him. "Call me Alex," Alex said, as he nodded. "Alex, are you a relative of the Potters?" he asked. "Yes, I am actually James and Lily's only child, since they were killed, a year after I was born," Alex said. "So in your reality, the Potters had a girl?" he asked. "Yes and no, since a prophecy indicated that a girl would face Voldemort, you hid me as a boy for fifteen years so my name use to be Harry Potter," Alex stopped, as she looked to the side. "There is a battle, Harry and others are fighting powerful wizards," Alex said. "Yes, in this reality, Harry is called a Weapon Mage, and has a four year old daughter, which I will explain later, but for now, I think you should head to the Gryffindor common room," Dumbledore said. "No, I can help, since I am both a mind and fire Elemental," Alex said. "Then follow me, I need to check on Shawnee," Dumbledore said, and headed out, as well as Alex.

As they walked, Alex told Dumbledore about her reality, and the other realities she visited and helped, Dumbledore listen to every word, and ask a number of questions, but the talk stopped, as Alex closed her eyes. "Sir, someone tampered with the Floo network, I am picking up a lot of dark activity all over the castle, they have got all the exits blocked, and dark wizards are heading to where the students are," Alex warned, and Dumbledore looked to her. "Go help them, I will round up the professors," Dumbledore said, and Alex teleported away.

In another part of the castle, Ron and Hermione and a number of DA students, were pinned down in the hallways behind suites of armors, as Death Eaters fired so many spells they couldn't fight back. "I hope that Harry hurries-" Ron started, but stopped as a spell was cast. "MASSA ASSORDA!" a girl yelled, and bright light hit almost all the Death Eaters and they fell stunned. "Hey guys a little help, Please!" Alex quickly said, as she dodged a number of spells by rolling behind a suite of armor.

As Alex fought, she had notice both her friends seem to be older, and knew from the wizard that taught her to open portals, each reality, she encountered, sometimes wouldn't be synchronized with her timeline, so she might be in the past, present or the future of another reality, and in this one, Alex knew she was probably a year into her future.

As Ron blasted a Death Eater, spoke to Hermione. "Who in heavens name is that girl?!" he asked, as he shot more spells. "She is the one who appeared in the great hall, who ever she is, she seems incredibly powerful, maybe as powerful as Harry-" Hermione said, as she sent a Death Eater flying, but was cut off, as a Death Eater, whom seem able to block all their spells called out to them. "I challenge one of you babies, to duel me," a woman's voice said. "Bellatrix Lestrange!!!" Neville called out in hatred, but Alex quickly stepped up.

All the DA members, watched in fascination as the stranger stepped up to the center of the hallway. "Lestrange, I will duel you, for the pain you caused Neville and other families!" Alex said, the fury barely contained. "And who are you little baby?" Lestrange teased in a deadly tone. "My name is Alexandra Potter, Stupefy!" Alex called out. "Protego" Lestrange called out, but the spell went threw her shield, and Lestrange quickly dodged it. "You'll pay for that, Avada Kedavra!" Lestrange called out and Alex just stood there as the beam shot at her until. "MURO DI LUCE!" Alex shouted, and a wall of light appeared, absorbing the curse. "How did you block that?!" Lestrange said looking shocked. "PETRIFICUS TOTALUS!" Alex shouted, and hit Lestrange in her chest, causing her to stiffen, and fall to the ground.

Once the duel was over, all the Death Eaters nearby, started to run, after seeing what Alex did, but none got far. "MASSA ASSORDA!" Alex shouted, and stunned the remaining Death Eaters. "Hurry and bind them!" Alex yelled, and teleported, leaving a shocked group of students.

Once Alex appeared, she was in the dungeon, where she felt a large group of students die. "Great I was too late," Alex thought, as she saw a hallway full of fallen Slytherin's. "Wait there they are!" Alex turned away, and ran down another hallway.

Not far from the fallen students, Alex came across Draco, but was surprise he was with a number of Gryffindor's. "Draco, you'll pay-" Alex thought, but quickly stopped herself from cursing Draco, when she felt this wasn't the same person who tormented her and her friends. "Great I guess I have to work with him," Alex thought, and ran towards the group.

Once Alex was close enough. "Hey guys, we got Death Eaters heading this way," Alex yelled, as they turn with their wands drawn. "Who are you?" Draco called out. "A friend, Dumbledore told me to help you," Alex said, showing her hands empty. "Alright, but we are watching your every move," Colin said, as Alex joined them.

Not far from where Alex met up with the Gryffindor's, they stumble upon the Death Eaters. "DEVII SCUDO!" Alex yelled creating a wall of light, just as the Death Eaters, shot hundreds of killing curses, that were reflected back at their casters, taking out almost all the Death Eaters. "Attack!" Alex called out, and everyone shouted a number of spells, that went threw the wall of light, that still protected them.

The battle was fast, since there were not many of the Death Eaters left, and Alex removed the wall of light, as the last Death Eater was blown into the wall. "Draco, look for the survivors and secure them, I will report this to Dumbledore," Alex said tiredly, since the shield spells had drain her, she teleported. "Lets do what she says, and make sure you check each Death Eater," Draco said, as he and the others, carefully check each of the fallen bodies.

As Alex appeared in the great hall, she just missed Harry apparating away, and the Weapon Mages, were quickly taking out the remaining Death Eaters. " STUPEFY! STUPEFY!" Alex quickly said running up to Dumbledore behind an over turned table, taking out two Death Eaters. "Alex, how are the students doing?" Dumbledore asked her. "The Slytherins were slaugtered, but the rest are fine, your order members are giving the Death Eater problems," Alex said, then turn to a group of Death Eaters, that was shooting spells at her shield. "REDUCTO!" Alex yelled, and a huge explosion threw them about, not all of them landed in one piece. "Oops, I still need to control that spell," Alex cringed at the sight, but turn to another set of Death Eaters. "MASSA ASSORDA!" she yelled and they fell stunned. "Good job Alex, but next time don't mess up the room." Dumbledore said, as they continued fighting.

In half an hour of continuous fighting, the few Death Eaters that seem to not want to end the battle, suddenly went stiff, and thanks to that, Alex, Dumbledore, and the few others, that were trapped in the great hall, quickly took them out, without any trouble.

Once the great hall was clear of Death Eaters, students, order members, and Weapon Mages, that were fighting in the hallways, arrived to tell the news, of the Death Eaters Defeat, and soon within a couple hours, the hallways was cleared of the fallen and wounded.

It was pass nightfall, as everyone who was not in the hospital wing, gathered in the great hall, they was talking excitedly as they ate, at the confirm death of Voldemort, and the hopeful recovery of their savior Harry Potter.

As everyone ate, Alex looked to Shawnee, whom was talking to Dumbledore. "I was not afraid, but they were mean, they destroyed your office, uncle," Shawnee said, telling Dumbledore what had happened in the office. "It is alright, later we can repair the damage," Dumbledore said reassuring Shawnee, then turn to Alex, whom was sitting with him. "Alex have you met Shawnee Potter, Harry's daughter?" Dumbledore said kindly. "No I haven't, nice to meet you Shawnee," Alex said. "You have daddy's magic in you, are you daddy in disguise?" Shawnee asked in a childlike voice. "No remember your dad is in the hospital wing asleep," Alex said. "Speaking of sleeping, Shawnee it is time for you to go to bed," Dumbledore said. "Do I have too, I want to talk to aunty Alex," Shawnee shyly said. "Sorry you have got to sleep," Dumbledore said, and gestured Alex to follow.

In a private room in the hospital wing, Dumbledore helped get Shawnee settled next to Harry, when Sirius and Remus appeared. "Shawnee, did you change some people into clowns?" Sirius asked. "I didn't," Shawnee said smiling, as Sirius came up to her. "Shawnee I know you did, come on, let's change them back, before you go to bed," Sirius suggested, but before he reach Shawnee, she disappeared. " great, look like they got to wait till morning" Sirius said, in defeat.

Once Shawnee was gone, Dumbledore turn to Sirius. "She will be back, Shawnee wont go far away from her father," Dumbledore said to assure them. "By the way, have you met Alexandra Potter?" Dumbledore said, pointing to Alex, sitting on a chair watching everything in interest. "No I haven't, nice to meet you," Sirius said trying to put the charms on Alex. "And nice to meet you Snuffles and Moony," Alex said, smiling at their shocked looks. "How do you know about our nick names?" Remus asked. "Please everyone, let sit and both Alex and I will explain everything," Dumbledore said, and everyone got seated, Alex told all.

Once Alex was done, both Sirius and Remus accepted where Alex came from, and was talking to her, till Dumbledore spoke up. "Let's head to bed," Dumbledore suggested, and Alex was shown to a guest room.

For two weeks Alex stayed to learned to do wandless magic from Harry, whom treated Alex like a sister, but Alex knew she had to leave, so on the last day of the second week, she decided, to try to go home.

Once Alex said her plans, everyone was saddened of Alex leaving, and Dumbledore made a big going away party for Alex. "Now Alex, I know when you return to your world, you will defeat your Voldemort," Dumbledore said, as they sat and ate. "Alex, if you want help, count me in to help," Harry said, since he knew Alex could come back anytime she wanted. "Harry, I should have more then enough help, for my last battle, but I will come back, to visit as soon I find my reality," Alex said, as she hoped it was soon.

The next morning, after saying good-byes to everyone, Alex was walking with Dumbledore down into the dungeon. "Do you think we will find this book, in our reality?" Dumbledore asked. "I'm sure of it, the wizard who told me of it, said it should be there, as long as Hogwarts was built," Alex said. "And this book, would have the history of Hogwarts from it being built, to all the spells that was cast in and around the castle?" Dumbledore asked. "It should, that is why I am looking for it, since every reality, is different, I hope the books will be written differently, and I could learn many spells that was lost during the years," Alex said hopefully, as they came to a statue of a phoenix. "Publicus" she said, and the statue was gone.

Once a copy of this reality's book was secure in Alex's backpack, Alex turned to Dumbledore. "I guess this is it," Alex said sadly. "You will see me again in the next reality, I'm sure of it," Dumbledore said, as Alex nodded. "But he would be probably different," Alex said with a sigh. "I guess I should be going," Alex said, as she turned around. "Portale magico," she said, creating the portal. "So long professor, I will visit when I can." Alex said, before stepping into the portal. "Good luck Alexandra Potter, I hope you find your way home soon," Dumbledore said, as the portal disappeared.

Unfortunately, Alex didn't, she will needed to pass threw hundreds more realities, before reaching to her own, and along the way, she gained the strength to overcome tough obstacles, made new friends, as well as fighting old and new enemies, and even-though some realities looked alike, there was realities unlike anything she could ever imagine, and there was a few she was more then willing to stay, but knew she had to leave in the end, to find her own reality, which she did, but always promising to return.
