A/N: This is my first story. Be kind please. Constructive criticism is welcome. This will eventually be slash. This first chapter is long. I don't know if the others will be as long. I'll try not to be too long between posts. Hope you enjoy.

Disclaimer: I don't own anything you recognize and will make no money from this. I won't remember to put this on every chapter so this covers the whole story.

Chapter One

The morning was peaceful as heavy mist rolled off the lake. Birds were starting to chirp again, finally overcoming the shock they had just lived through. Small creatures leapt from the lake making tiny splashes. And a few tentacles reached out of the water trying to catch the jumping creatures.

The scars in the earth were beginning to heal themselves. Fresh grass and other growing things were beginning to grow over the gouges made by rogue spells. Nature always found a way to heal the damage caused by man. The people who lived in this place were glad to see that the land was recovering from what had happened here.

There was a disturbance on this peaceful morning that caught the residents off guard. Seemingly from no where a lone cloaked figure appeared beside Black Lake. The tall figure seemed to be staring up at the damaged castle next to the lake, deep in thought. Was this person considering approaching the castle? Or were they simply stunned by the amount of damage Hogwarts castle had sustained during the battle? How had they gotten past the wards newly repaired wards?

Minerva McGonagall and Severus Snape hurriedly approached the doors of the castle concerned over this unidentified figure. Minerva was still on guard after the war and the battle that had happened on the grounds of her beloved school. Severus, barely recovered from the injuries he had sustained during the battle and from Nagini's venom, was equally on guard. Everyone knew that some Death Eaters had escaped the battle and the aurors.

Together, wands in hand, they decided to approach the still stranger. They crossed the scarred lawn quickly in case the stranger decided that they had been still long enough. No one else was going to attack the castle on their watch.

When they reached the cloaked stranger it was Severus who spoke. "Who are you and why are you here?" he demanded sharply.

The stranger jerked slightly, having been startled out of their thoughts, before two slender, tattooed hands emerged from the folds of the cloak and reached up the lower the hood. The woman that was revealed was young, not long into adulthood, and startlingly beautiful. Her hair was long, black as onyx and streaked with deep red. Her skin was pale and flawless. Her cupid's bow lips were naturally red. Her eyes were brilliantly, almost unnaturally, blue and framed by long lashes that were the same black and red mix as her hair.

"Miss Nagero?" Minerva blinked as she looked the girl over. To say she was surprised was an understatement. No one had expected to see this girl again.

"Good morrow Professors," Trinity Nagero gave them a soft smile of greeting before returning her attention to the castle, "What happened here? It's only been three years since I left for home."

Severus's voice was cold as he answered her. "War happened Miss Nagero. A war that was brewing long before you returned home."

"And it spilled over to the school?" Trinity growled, "Where was the Ministry? They were under strict orders that Hogwarts was to be protected. And we were to be notified the moment they realized that they couldn't fulfill their duties."

Minerva sighed heavily before explaining, "The Ministry fell to Voldemort long before he moved on the school. There was no one left to inform Karant after that."

"Dumbledore has the means to contact my mother. She made sure of that before she left Hogwarts," Trinity couldn't seem to tear her eyes away from the school that had been her home for the better part of seven years, "And Sofinara or Lycinaya would have been able to get in touch with us."

Minerva glanced at Severus before looking back at Trinity. "Dumbledore was killed before the Ministry fell and he took whatever secrets he had to the grave."

"As for the Contaxis twins," Severus shifted, "they threw themselves into the war. I can only assume they were too distracted to contact Karant."

Trinity nodded and fell silent. She was not troubled by Dumbledore's death. Much of the war could have been avoided if he'd shared his secrets. As for the twins, she wasn't surprised they had involved themselves in the war. They were very much like their mother and brother in their desire to fight to protect. They were also headstrong enough to believe that outside help was unnecessary.

She should never have left. And she wouldn't have if she'd had a choice but her duties in Karant made it impossible for her to stay. Her mother had needed her at home but Kalia could have lived without her just a bit longer. Karant would have been fine for a couple of years. Had she been here the damage wouldn't have been so great. Hell, Kalia should have been here for this, leading the armies of Karant. Witches and wizards fell under the rule of Karant.

"Why are you here Miss Nagero?" Severus asked again to draw the girl's attention back to them.

Trinity came out of her musings and looked him in the eye, "I believe we should discuss that inside Professor."

"If you believe that is best," Minerva said before turning to lead the way inside.

Trinity followed the two professors in silence. Her eyes moved rapidly to take in everything. The broken and burned halls caused sadness to well inside her. The damage caused by dark magic wouldn't be easily repaired. It would take months, if not more, before the castle was put to rights. It angered her that this hadn't been prevented.

Before she knew it they were in the headmaster's office. Trinity removed her traveling cloak and placed in over the back of a nearby straight-backed chair before sitting down. She saw both professors take their own seats while staring at her arms.

The markings were hard to ignore she supposed. Her left arm was completely covered in swirling red and orange flames from her shoulder to her hand where licks fire met at the red rune on her palm. Her right arm was a pale greenish blue that was shot through with blue and white lines that splintered out from random places from her shoulder to her palm where the fracture lines met where a blue rune rested. These were marks of her power and a sign of how powerful she really was.

"Now to answer your question," Trinity looked at Minerva who was sitting behind the headmaster's desk, "I'm here to see Harry Potter."

To say this answer shocked both professors was an understatement. Both of them tore their eyes away from her arms to stare at her with gaping mouths. For long moments neither could come up with any words.

"Why would you want to see Potter of all people?" Severus demanded harshly after the prolonged silence.

"Because he is my brother."

Minerva's mouth opened and closed like a fish before she forced out, "B-b-brother? How is that even possible? Why didn't you say anything before?"

Trinity sighed and settled more comfortably in her chair. "My mother only told me who my father was a month ago. I came back to this world as soon as I was able."

"James Potter was your father?" This came from Severus.

"Yes. Apparently he and my mother were together once and she left Hogwarts pregnant," Trinity told them, "She was not the only one. The other three girls from other worlds were pregnant as well."

"What!?" Severus barked while Minerva was trying to wrap her head around the horror of a group of pregnant students on her watch.

"Drexnata Haunting was pregnant with Sirius Black's son. Olympia Contaxis was pregnant with Remus Lupin's son. My mother was pregnant with me," Trinity paused and gave Severus a hard look, "And Darkana Fairdane was pregnant with your daughter Professor."

"Dark was pregnant?" Severus slumped in his chair. His voice was faint when he spoke again, "I have a daughter. Why didn't she tell me? I taught my own child and never knew it."

Trinity looked at him with pity. "From what I understand, you had already fallen in with the Death Eaters. Darkana had already ended things with you. As soon as she returned home, Queen Darian fell ill and Darkana had to take the throne. Telling you fell to the back burner and she had no idea that you would be teaching here. Arabella had no idea who her father was, none of us did. Our mothers decided to tell us all together.

She and Devonash, who is Black's son, will be coming here after their honeymoon to see their fathers. Xebrex will come to find out about Lupin after he visits with his mother and sisters. I came to find my brother and possibly get information for the others."

Minerva cleared her throat. "I'm afraid both Sirius and Remus were killed in the war. Remus does have an infant son, Teddy, who is being raised by his grandmother. Sirius was Harry's godfather and named him his heir as Sirius was the last of the Blacks. As you see, Severus is here, if a little worse for wear."

"I shall tell them when we speak again," Trinity was saddened by so much death, "Now, what of Harry?"

"He is at home. He was injured during the final battle and has shut himself away there while he heals," Minerva explained.

Trinity frowned at this. Harry was injured? How badly? Should he even be on his own? She had to see him right away. He was her little brother. Family was important, something to be cherished and taken care of. If he wanted a sister, she would take care of him whether he liked it or not.

"Take me to him now," and it was not a request.

HPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHP

Trinity stepped out of the fireplace and shook the soot from the hem of her cloak. She despised floo travel but apparently it was the easiest way to reach Harry. She stepped forward into the dark room trying to locate Severus. He had come through first to reassure Harry if he had been in the room.

This sitting room was positively depressing. What little light was in the room seemed to be unable to push the darkness back. The furniture was old, worn, and neglected. Dust and cobwebs were thick on every surface. And she was sure there was something unpleasant living in the heavy black curtains she could just make out across the room.

Severus was muttering something about useless elves as he strode confidently to a heavy door that Trinity hadn't even seen. "Be quiet in the hall," he told her shortly, "We don't want to wake that horrid portrait."

Trinity nodded even though he wasn't looking at her and followed. The house was dark and musty everywhere. The elf heads on the wall were disturbing to say the least. Drexnata would be horrified by the display. Creatures fell under her rule and she would punish those who did this severely. There was an evil feel to this house that made her skin crawl. No one should be trying to recover in this place.

They made their way down to a basement kitchen that was remarkably different from the rest of the house. It was warm and inviting. Every surface gleamed in the bright lights. This room was lovingly cared for. And that care seemed to be winning the battle against the darkness that permeated the rest of the house.

"Kreacher!" Severus called sharply, startling her from her observations.

There was a loud crack and a little elf was standing before them. The ugly creature was wearing a gleaming gold necklace and a clean tea towel like a loincloth. His bulbous eyes looked at the two of them with suspicion. "Half-blood called sir?"

"Where is Potter?"

"Master Harry in the library sir." His voice reminded her greatly of nails on a chalkboard.

"Bring him to us. Please," Severus bit out.

Kreacher disappeared with another crack. Trinity looked at Severus with an arched brow. He did not seem the type to say please, especially to a servant. "Potter demands politeness when dealing with the help," he told her.

Before she could respond Kreacher had returned, bringing Harry with him. She watched as Kreacher helped the boy into a chair. His short black hair stuck up in every direction, like he'd stuck his finger in a light socket. His brilliantly green eyes were dull with what looked like pain. His skin was pale, shockingly so, like he hadn't seen the sun in months. There was the lightning bolt scar that she remembered but there was a new scar that made a mess of his face.

Starting under his left eye, covering most of his cheek and neck disappearing into his shirt, it looked like he'd been mauled. There was no telling how big the scar really was. The long, jagged marks were still red and looked as if someone or something had tried to rip off his face. He was moving stiffly, like his leg didn't want to move on its own. She was torn between wanting to see the extent of his injuries and hoping that she never had to.

He shifted uncomfortably in his chair as he thanked the elf. Then he focused on Severus. "What are you doing here? And who is she? You know I want to be left alone," he demanded in a voice rough from disuse.

"This is Trinity Nagero. She was a student three years ahead of you so you may not remember her," Severus told him sharply, "She wanted to meet you and she's not someone even I can say no to."

Harry turned hard eyes to Trinity. "Why would you want to meet me? If it has anything to do with the war, you can go ahead and leave."

"It has nothing to do with the war," Trinity assured him before motioning to the chair closest to him, "May I?"

He looked her over once more before giving a jerky nod. Trinity smiled softly before pulling out the chair. As she sat her eyes never left her brother even as she was aware of Severus moving around the table to take his own seat. Harry simply waited for her to speak again.

"I wanted to meet you because..." Trinity paused as she was caught off guard by a sudden flare of nerves. She cleared her throat twice before the words just tumbled out of her mouth, "I'm your sister."

Harry's mouth fell open in shock and he blinked rapidly, faster than she thought possible. Trinity did not take her eyes from him while she waited for him to recover. After ten long minutes she was beginning to believe she broke him. Even Severus seemed to be concerned.

"Ex-excuse m-me?" Harry finally stuttered, "W-what? How?"

"James Potter was my father," Trinity told him, "Apparently there was a lot of fire whiskey involved and my mother left Hogwarts pregnant."

Harry frowned deeply, "Why didn't I know about this? My parents were together at school. My father wouldn't have..." he trailed off.

"According to my mother their relationship was very new and they were still trying to get used to each other. James and Lily had a terrible fight. Lily, in her anger, told him they were through. James was very upset and very drunk when my mother found him. Mother loved James the way he loved Lily so she offered him comfort. James took advantage of her offer and she took advantage of his drunkenness. She knew she would never have another chance because James would never have betrayed Lily in his right mind.

James never remembered what happened with Mother. He and Lily made up two days later. When mother fell pregnant she said nothing. James was the kind of man who would want to marry the mother of his child whether he loved her or not. Mother, more than anything, wanted James to be happy and Lily was his happiness. So Mother hid her pregnancy and returned home after graduation," Trinity explained to her brother.

"How long was Kalia pregnant in school?" Severus questioned.

"Nearly the entire year. She was very careful with glamors and bulky robes. I was born almost as soon as she returned to Karant. I'm the eldest of the Hogwarts babies by far."

"Why didn't you say anything before?" Harry demanded abruptly, "Am I suddenly worth having as a brother now that I'm the 'Savior'?"

Without thinking of her actions, Trinity reached for him and took his hand. "No Harry, it has nothing to do with this 'Savior' business. I didn't even know about the war coming to a head until I arrived today," she explained gently, "Mother told me about my father a month ago. I demanded to be released from my duties and returned here as soon as I was able. I rearranged everything, upended my life, and traveled between worlds as fast as possible to get here. There is nothing more important than family Harry."

Harry seemed stunned by her impassioned words. He stared down at where she was still holding his hand. "Karant? Why does that sound so familiar?" his asked quietly without moving away from her.

It was Severus that answered this. "Don't you ever pay attention to your lessons Potter?" he asked snidely, "Karant is the kingdom that rules over all humans with access to magic, like wizards, no matter what world they're in. It used to be in this world centuries ago but was moved to a different dimension when muggles became a threat. Kalia Nagero is the queen of Karant and Trinity is her heir."

Harry's eyebrows shot clear into his hairline. "You're a princess?"

"Yes," Trinity answered with a half smile, "and that brings up something else. A gift from my mother."

Confusion filled green eyes searched hers. "Why would your mother give me a gift?"

"My mother loved James Potter greatly. She was devastated to learn that he and Lily were both gone. Had she known that you had been left alone nothing would have stopped her from bringing you to Karant. We are family," Trinity explained, "She feels that she failed James, me, and, most importantly, you. So she wants to make you a prince of Karant."

Both Harry and Severus gaped at her like she'd suddenly grown a second head. She'd never seen the Potions Master look so inelegantly flabbergasted in her life. Poor Harry looked as if he might just faint from shock. Something like this had only happened once before in Karant's history. Catherine St. Clair, the former queen of Karant, had made Kalia a princess because she had no heirs of her own. Catherine had disappeared as soon as Kalia came of age.

"What does that even mean?" Severus barked out suddenly.

Trinity looked over at him and heaved a heavy sigh before answering the question. "It means that he'll have a permanent home in Karant, a boost in funds, and a boost in power. It means that if something happens to me and my mother has no other children he would be the Heir of Karant. It means that he will be protected by the full power of Karant. Even here the Ministry can't touch him. Anyone who tries to harm him in any way will feel the full fury of of myself and my mother. No one, and I mean no one, will be able to use him, abuse him, steal from him, lie about him, or force him to do anything he doesn't want to do ever again. He has one of the most powerful families in any world to love and protect him. It means he will never be alone again. All the things he would have had if Dumbledore hadn't kept his own council."

Her fervent words seemed to amaze Harry. It saddened her greatly to know her brother had known so little acceptance and support in his life that a few words floored him. No matter if he decided to take her mother's gift or not he would always have Trinity's love, support, and protection.

"And if I say no?" Harry asked worriedly.

Trinity squeezed his hand as her eyes found his. "You are my brother Harry. I love you, never doubt that. You will always be welcome in Karant even if you aren't a prince. You will always have my support and protection. And I'm going to be spending all of my time getting to know you for the foreseeable future. My mother has released me from my duties for as long as I need. Even when I'm ready to resume my duties I won't be returning to Karant if you do not wish to live there. As long as you want me for a sister, you are going to be stuck with me."

"I won't insult your mother if I don't accept?"

Trinity smiled softly at him and shook her head. She was caught completely off guard when Harry awkwardly launched himself into her arms. Trinity grinned at Severus as she held the boy. She thought she saw the corner of his mouth twitch upwards before she rested her cheek on the top of Harry's head.

HPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHP

She didn't get an answer that night. Much to her surprise, Harry had fallen asleep in her lap. She and Severus had talked softly while he slept. Kreacher had appeared about and hour after he dozed off and taken Harry to his room. Severus had followed after the duo to check on Harry's healing. Kreacher had returned to feed her.

Severus had left for Hogwarts with a promise to return later. Out of boredom Trinity had gone to explore the house. She destroyed every dark object she found, eradicated some particularly vicious doxies, killed four boggarts, and banished a ghoul.

The raging portrait of a rather vile woman was stuck to the wall. Trinity silenced the annoying woman while she tried to figure out a way to remove her without destroying the portrait. After a while she shrugged and set the portrait on fire. She carefully watched the fire and put it out once the job was done. Smiling, she cleaned up the mess and hoped that Harry wouldn't be too upset.

She found a tapestry that had been hexed quite a few times. It was stuck to the wall as well but as it was a family tree she didn't want to destroy it. Unlike the insane portrait it had done nothing to offend her. So she simply repaired where it had been hexed and left it alone.

After that Trinity called Kreacher and politely asked for a place to sleep. She was exhausted. Traveling between dimensions was tiring and she'd used quite a bit of magic in the few hours since Harry had fallen asleep. Even with as powerful as she was she had pushed herself a bit too hard today.

Kreacher showed her to a dreary, but clean, room with two beds. She thanked him with a smile before falling across the bed and promptly falling asleep. She never felt the little elf tucking her into bed.

HPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHPHP

The next morning found Trinity dragging herself out of bed late. Princess she may be but a morning person she was not. She stumbled her way down to the kitchen grumbling about waking before midday. Stupid royal training getting her out of bed whether she wanted to be or not.

Harry was already awake and had been for hours. He sniggered at his sister's grumbling. Kreacher took one look at the bleary eyed woman and promptly served her fresh coffee. Trinity's response was something along the lines of, "Thanks for not giving me tea." Which made Harry laugh out right. She glared at him as soon as she could focus her eyes.

"Not fond of mornings?" Harry asked her cheerfully.

Trinity snorted as she downed her entire cup of coffee, which Kreacher was quick to refill. "Not in the slightest," she finally answered him.

Harry smiled, sipping his tea. Then he said, "I noticed Mrs. Black's portrait was missing..."

"I was going to think of a way to simply remove her but she annoyed me, so I burned her off the wall. I'm sorry if that bothers you."

"Oh no, I'm fine with it. Been trying to get her off the wall for years."

"Good. I also got rid of a few pests and a mess of dark objects," Trinity shrugged, "I was bored."

Harry was astonished. "You must be powerful because those were some nasty objects."

Trinity nodded, "The people of Karant and other worlds are more connected to magic. I have more power than all the wizards in Britain combined. You're the most powerful wizard in this world. I can see your magic flowing and pulsing all around you. If you decide to accept Mother's gift, your power will grow significantly. You won't be as powerful as I am because I am Heir of Karant, like I'm not as powerful as Mother because she is queen."

Harry nodded and promptly lost himself in his thoughts. Trinity muttered something about bathing and left the room. Did he want to be a prince? The protection offered would be nice. He trusted the Ministry about as far as he could throw them without magic. He didn't need money or power, he had more than enough of both. But his own family was something he desperately wanted.

The Weasleys hadn't been around since the end of the war. He hadn't even heard from Ron or Hermione in months. Other than Madam Pomfrey and Professor Snape no one had visited. Ginny hadn't been able to stomach the sight of his injuries. The aftermath of the war had shown him how alone he truly was.

Trinity was his sister, his very own family. She was a princess and extremely powerful. She wanted nothing from him, needed nothing from him. Professor Snape trusted her and deferred to her in a way he hadn't deferred to Voldemort or Dumbledore. She had no need for his money or his fame. She'd changed her entire life simply for a chance to know him. No one had ever done something like that for him before.

And then there was Kalia Nagero, Queen of Karant. She'd loved his father. The way she'd been with James Potter was a bit underhanded but she'd stepped aside so James could be with his true love. This offer was a way for her to make amends for keeping Harry and Trinity apart. And she wouldn't be offended if he turned her down.

Trinity reappeared in jeans and a black t-shirt, her hair still damp from her shower. She hardly looked any more awake than she had before she went upstairs. Kreacher was quick to supply more coffee. Harry wasn't exactly a morning person himself but he was better at mornings than his sister it seemed. He didn't bother to disguise his snort of amusement.

Instead of teasing her, he brought up the offer. "I'm not sure I want to be a prince."

Trinity shrugged. "It's an open ended gift. I don't need an answer anytime soon. It doesn't matter if you give me an answer now or ten years from now. You have plenty of time to think it through."

Harry nodded, relieved. It was a big decision. He wanted to think it through. He had spent enough time simply rushing into things in his life. And that rarely ended well for him. And there were many people that would agree he was rash and emotional. Having the time to think was good.

"That tapestry upstairs looked like a family tree," Trinity said after finishing her coffee, "Yours?"

"In a way, I suppose. It's the Black family. Sirius Black was my godfather and named me his heir when he died."

"Then you have a brother too, after a fashion."

Harry had thought she was done surprising him. "Huh?" was the best he could manage.

"Devonash Haunting, Prince of Hallasta, is Sirius Black's son. He's married to Arabella Fairdane, Princess of Iouna, Severus Snape's daughter. They'll be coming to this world soon. And Xebrex Contaxis, Prince of Unapegon, is Remus Lupin's son. He's already in this world visiting his mother. His sisters, Sofia and Lycia, were in the same year as you. I'm sure Brex already knows about Remus. When Ash and Bell meet with Severus they'll learn about Sirius," Trinity explained, "When Ash learns of your relationship to Sirius he will see you as his brother. The four of us are family and now you're a part of that."

"Did anyone know that these women were pregnant? Because neither Sirius or Remus ever mentioned having a son."

"Severus was on a dark path and already falling in with Death Eaters, so Darkana never told him. Drexnata's father was ill so she had to rush home before she even knew she was pregnant. Her father died and she became queen and time got away from her. As for Olympia, I don't know if she told Remus or not. Considering the father's feelings has never been high on her list of priorities."

Harry fell silent, thinking. After a moment he murmured, "Yesterday I had no family. Now there's so much."

Trinity smiled at him. They were quiet while Kreacher served a light lunch. She complimented the elf lavishly while she enjoyed yet another cup of coffee. Harry had never seen anyone drink so much coffee before.

"So, do you want to come to Karant? Stay in England? Travel around? Or pick some random place to live?" Trinity asked as she finished eating.

Indicating his leg, Harry said, "I'm not really up for much traveling and I don't think I'm ready to visit Karant. I know that I don't want to stay in England, but where would we go?"

Trinity waved her hand and a weird little machine appeared on the table in front of Harry. It was colored like a rainbow. There was a rectangular window near the top and beneath that was a round black button. Harry shot Trinity a confused look.

"My Aunt Pia called it Location Roulette. She lived in this world while we were attending Hogwarts. To make things interesting, since moving between worlds is hard on children, she came up with this little box. On holidays we would press the button and it would give out a random place. No matter where it said, that's where we would spend our holiday."

"So, just push the button and we'll live wherever it says?"

Trinity nodded. "Every town in this world is in there. Go ahead and give it a shot. If you want to that is..."

Harry considered the machine. He actually liked the randomness of the thing. Taking a breath he pressed the button. Lights appeared in the window and flashed like a strobe light. He and Trinity waited with baited breath. Both leaned over the machine when the lights stopped.

"Forks, Washington, United States of America."
