So since 'The Emerald Rose' turned out so well, and I am still working on the other two stories with it, I thought I'd try this. It just popped into my head one day and there are not a lot concerning this pairing. I do not plan on making this like Emerald Rose with just a different pairing. Things will be different.

Still a gender-bending fic, Harry will be a girl. Will be paired with someone else this story. No, not Law. There are enough out there with Law/FemHarry pairing… and I can't think of a good one. Maybe later on.

Anyway, we continue onward!

Here the Chapter Starts

How could they simply forget her? It boggled his mind how easily it was for them to disregard their only daughter for her twin brother. Don't they realize that little Celosia is their child as much as Aiden?

Sirius shook his head, scoffing under his breath as he turned towards the little girl squatting on the stairs, grasping the bars she was peeping through while everyone else sang 'Happy Birthday' to her brother. Not a word even whispered to her. Not a single smile or well wish.

Was she crying? No. Sirius realized early on these little facts about his goddaughter. Little Celosia never cries. She simply stares with a blank expression, her eyes observing every detail without letting a drop of salty tears fall. Her lips never quiver, nor frown, nor smile. Her cheeks never flushed in embarrassment or anger or distress.

He also noticed, though, that the brightness of her forest green eyes faded each time she was overlooked. Each time she achieved a goal and wanted to tell her parents, she was ignored in favor of her brother for completing a mediocre task compared to her much more impressive one.

Aiden takes his first step, Celosia was already climbing the stairs without assistance. Aiden said his first word, Celosia was already speaking full sentences. Aiden realized that fire is hot, Celosia already understands that the changing color of leaves mean the change of the seasons. Aiden still believes in Santa Claus like most children, Celosia refuses his existence and prefers to celebrate Yule.

The difference in their intelligence and behavior was astounding, yet James and Lily completely disregard Celosia's accomplishments by focusing on Aiden. And little by little, as her parents gushed over their son, his tiny little goddaughter is slowly losing her will to live. Why should she continue on living with a family that hardly acknowledges her existence?

His eyes narrowed as he looked to his best friend and his friend's wife. They used to be good people that loved both children equally. Then Voldemort attacked. James and Lily were unconscious, spared to be made examples of later on after Voldemort kills the twins. No one knows what happened after that. All anyone knows is that Voldemort was defeated. Dumbledore declared that Aiden is the one who did such a feat, the V cut on his chest all the proof he needs, claiming Celosia's lighting bolt cut on her forehead must be from falling debris. From then on, Celosia was ignored. James and Lily changed into strangers.

Huffing, he went over to the couple once the song was over and the cake cut into. Pieces were already on small plates, each one with a fork to eat with. Sirius grabbed only one plate and left the room, ignoring the curious looks from the Potter couple.

Celosia watched him closely as he approached with a gentle smile on his face, holding the cake out for her to take. Her hands slowly released the bars she was holding, reaching between them to take the plate cautiously, like she was expecting it to be snatched away. Sirius conjured a candle shaped into a five and lit it, placing the candle on the small piece.

"Happy Birthday to you," he sang softly. "Happy Birthday to you. Happy Birthday, dear Celosia. Happy Birthday to you."

Her eyes were wide as he sang the song and her lips shook. She tucked them into her mouth, biting down on them as her watery gaze looked to the candle.

"Make a wish," he encouraged. "Blow out the candle."

She inhaled deeply then let out a quick puff, the small fire flickering from existence. Sirius made up his mind as he watched her calmly eat the piece of cake one tiny bite at a time.

Here is a line!

"You want to what?" James asked incredibly.

"Take Celosia," Sirius answered calmly. "You hardly pay any attention to her anyway. You're always focusing on Aiden."

"As we should," Lily snapped with a huff, crossing her arms. "Aiden needs us!"

"So does your daughter!" Sirius snapped back, his lips baring his teeth. "You don't see her like I do! Just last night, she almost cried because I sang Happy Birthday to her! While you two were in the other room with Aiden and everyone else! No one said anything to her or gave her anything!"

"He's the Boy-Who-Lived, of course he's going to get the attention of most people," James pointed out. "You want to break our family apart because you think we're neglecting our daughter?!"

"What was her first word?" he suddenly asked.

James blinked, reeling back in slight surprise. "Umm… I believe it was Dada."

"That was Aiden," the Grim Animagus pointed out. "Her first word was 'lonely'. And she knew what it meant. Where did she take her first step?"

"In the living room," Lily scoffed, rolling her eyes like the questions were a waste of time.

"Aiden again," he informed firmly. "Celosia's first step was on the top floor. I caught her before she could fall farther than two steps down. She almost killed herself and neither of you noticed!"

"What is your point?!" James shouted, slamming his hands onto the table.

"My point is that you two don't even know she's there!" Sirius roared back, knocking the table away. James jumped back in shock. "You call yourself her parents, but neither of you can see that she doesn't even smile! Or cry! Or laugh! Or even talk to you anymore! You're hurting her more than Voldemort ever could if he had the chance!"

"How dare you compare us to him!" Lily screeched.

"I am her godfather, meaning it is in my right to take her from you if I believe you're not taking proper care of her," he informed coldly. "All it would take is a trial, me against you two. Every little fact about how much you are neglecting her will come to light and you won't be the perfect little family you like to think you are. So make this easier on yourselves. Sign Celosia into my custody. Let me take her in and raise her like she should be raised. Like a real daughter and not some doll to overlook on a shelf while it gathers dust."

"We do not-!" James started, but was cut off.

"Fine!" Lily sneered. "You want her so bad, take her. Aiden needs us, and without her here, we can finally pay our full attention to him."

"You were doing that anyway," Sirius growled, yanking the papers from his coat. "Sign these and Celosia is mine."

The redhead snatched the papers from his hand, turning to the desk where the quill and inkpot rested. James paced angrily, glaring at him for his accusations. Sirius didn't care. He had watched the behavior go on for four years, and enough is enough. Lily called James over, making him sign his name as well before she shoved the papers into Sirius' hands.

"Thank you," a soft voice said, causing the adults to look over. There stood little Celosia, a fluffy black dog plush toy received from Sirius just yesterday clutched in her hand. Her green eyes were looking up at Sirius, but she wasn't smiling or crying. Despite that, Sirius could see her gratitude. "Thank you, Uncle Padfoot. Can we go home now?"

He smiled back at her, kneeling where he stood and held out his arm. "Yeah, we can go home now."

Unlike most children, she did not run into his arms with a giggle or a smile. She calmly left the door and walked over to him steadily, resting her head on his shoulder as his arms wrapped around her, securing her as he stood back up.

Celosia stared at her parents with a blank gaze, ignoring their shocked expressions at her act. They probably thought she would scream and cry about being taken away from home. No, she won't. This isn't home. And Sirius will be nicer to her. She'd rather have him as her father, anyway. He sees her. He hears her.

They don't.

Here is a line!

He couldn't say he was surprised. The Potter family stays in the headlines, yet not even a hiccup of Celosia's disappearance from their tiny circle. The public didn't know of her, and her parents weren't going to announce how their best friend 'stole away' their daughter.

Bringing Celosia into his home took a bit of adjusting, he'll admit. Most times, she's so quiet that he would turn the house upside looking for her. Most of the time, he found her in the library, reading a book open on her lap. Not a children's book, either. A thick tome of information, which she soaked like a sponge. He started to believe she was making it a game when he started finding her in new places.

He's found her under the kitchen table once. Another time, hiding in the towel closet. Under his bed. In his parent's old room. Even under that curtain he uses to cover up his mother's portrait. Once, he even found her in Kreacher's tiny cupboard room.

In a way, he thinks she was testing him, wanting to see how far he'll search for her. If he really does care enough to look anywhere and everywhere should she go missing. When she stopped hiding from him, he likes to think he passed her little test.

She still hasn't really smiled at him. She hasn't frowned either. She's mostly expressionless, despite his best attempts to get even a giggle. The only way she showed her emotions were through her body language and her eyes. While she won't laugh or cry, her eyes would darken in depression or light up in curiosity. She would tuck her head down when embarrassed or tilted it when she was curious. Occasionally, her lips would twitch when he does something particularly hilarious. Small progress, but progress all the same.

Here is a line!

"I think we should move," he decided, looking to his goddaughter across the table. She looked up at him, her head tilted slightly. "Let's face it, this place isn't the best place to live. What with 'mother dearest' screaming at us and Kreacher being… well, Kreacher." Though his house elf does love little Celosia, pampering her with sweets and doing anything she asks, Kreacher isn't the best of company.

"Where would we go?" Celosia asked, blinking curiously at him.

"I'll let you choose," he replied with a grin. "Anywhere you want."

"What if I want to live on an island in the middle of an ocean?"

"We'll make it happen."

"What if I want to live in another realm?"

"We can make it happen," he said easily, smirking at her confused expression. Reaching out and patting her hand, he rose to his feet. "Come on. I'll show you something really cool."

Her eyes watched him before she followed after, her step silent even on the hardwood flooring. He led her to the basement door, casting a quick Lumos to light the way downstairs, then started lighting various candles in the area.

Celosia was quite curious as to what her godfather wishes to show her. She has never been in the basement, Sirius having warded it to keep her out so that she wouldn't take a tumble down the dark stairs and break her neck. While she did not like being blocked from her exploration, she couldn't help the slight warmth that filled her with the knowledge that he does care enough to block her from areas for her protection.

Once all the candles were lit, her green eyes zeroed in on the arch near the back wall, torn and ripped curtains covering it. Runes were carved into the stone, each one with a gem in the center. It looked old and ready to crumble at a single poke, but she thought it beautiful still.

"Do you know what a Realm Jumper is, little Celosia?" Sirius asked, looking down to her with a smile.

She nodded, having read the term in a book from the Black Library. "They travel the realms," she explained calmly. "So long as they have a way back, they can always make it to their home realm in order to go to another. They often build gateways for security to and from realms."

"Very good!" he praised with a wide grin. "Well then, want to guess what this is?" He waved his hand to the arch.

"A Realm Gate," she identified with a sharp nod.

"Exactly!" Sirius praised again, not reaching out to pat her head after the last time he did so. She ducked down to the foreign touch and shied away. He figured he was moving too fast for her to properly adjust, so let her choose when she was ready for certain touches. "One of my many great uncles was a realm jumper, and he created this Gate. He also wrote a book about all the realms he's visited and how to get to them from his Gate. I'm sure you already found the book in the library."

She nodded. That book was full of wonders she truly wanted to see, but one realm sounded perfect. And she wanted to go there to live.

"Of course you did," the man chuckled fondly. "I bet I could say a title and you'll tell me exactly where it is in there."

Celosia nodded again, having the library memorized and sorted in her mind. As well as all the books and their subjects, having sorted them herself after finding how disorganized the library was until she got a hold of it. Her new guardian thought it was funny that she managed to do such a feat by herself within three days. He did try to help, but she chased him away.

"So if you want to live in another realm, we have this down here," he summed up, patting the old stone fondly. "I don't know how to make it work, but I believe you do. Otherwise, you wouldn't have asked about moving to a new realm."

"So… can we?" she asked lowly, looking up to her godfather with wide eyes. She knows that Aiden's fame will soon fade once the truth of that fateful night came to surface. When that happens, she will have no peace and would be ripped away from Sirius by her parents, who would want her back if only for the limelight. To act like they loved her all along, even though no one ever even heard of her.

"Whenever you want," Sirius answered with a small nod of his head. "Let me know and we'll pack what we need. Then we'll move whenever you feel ready."

She felt ready now. "We should pack."

Here is a line!

"This will change our money into that realm's currency," she explained, grabbing a pouch and dropping gold, silver, and bronze coins into it. Next, she grabbed two necklaces and three earrings, one for Sirius and two for her to use. "The necklace will let us speak their language, and the earrings will let us hear it. Even when we're using them, we're still learning the language so we don't depend on them forever."

"That's all handy," Sirius commented, accepting the necklace with the obsidian tooth and black diamond earring.

As he put them into place, he carefully watched Celosia put on her own emerald teardrop necklace then her green topaz earrings. She didn't once prick herself with the sharp point, slipping it into the near invisible hole she put in herself earlier that day.

"Anything else?" he encouraged for her to reveal her knowledge. He did look over the book his many-times great uncle wrote years ago. But after being denied the privilege of showing how intelligent she is, he feels that it would be best to encourage her to show-off a little bit. For now. If she gets too out of hand with it, he'll have to find some way of teaching her how to be humble.

"When we pass through the Gate, after setting the realm destination, we will be dropped into a random time period and location in that realm," she explained. "For example, we could spent five years in that realm while only two pass here because of us being pushed back three years before now, or we could spend one year there but ten have passed here. There is no control over time or exact location unless certain runes are put into place."

He nodded with a smirk. "Very good, Celosia," he complimented. "You are so much brighter than even your mother."

She blinked up at him, her eyes shining as she tucked her head down. "Thank you," she whispered.

"Now… do you have everything you will need?" he asked, giving her a playful scrutinizing gaze.

"I have my own bag of money from what I took after leaving them," she listed. "I put a lot of my clothing for all seasons into my trunk, and lots of books. You already set the Feather Light Charm on it, as well as an Expansion Charm. So I managed to pack blankets, pillows, toiletries, our toothbrushes and lots of toothpaste – you forgot yours, so I grabbed it for you -, and my toys."

"Here I was hoping to forget on purpose," he sighed dramatically, earning a small snicker from his goddaughter. "I packed plenty of preserved food, hopefully enough to last until we get a solid roof over our heads. A few weapons for defense and hunting, you will learn how to use some of them when you're older. It's a good survival skill to have. And a tent for temporary living quarters, again until we find a more permanent home. I also packed a few books myself, and stowed away half of the Black Fortune, so we should be set money wise for quite a while. Is there anything else we could have forgotten?"

Celosia thought for a moment then shook her head. "I can't think of anything pressing right now," she answered firmly. "If we need anything else, we should find a town, city, or village and see if we can find things to buy there."

"Good idea," he accepted. "What about something like a map?"

"I have the book," she informed, pulling her trunk closer to her. "Where we're going, there's a whole chapter on it. I can tell you more when we get there, if you want."

"Just tell me one thing for now," Sirius suggested, squatting in front of her. "Can we use magic there?"

His goddaughter nodded. "That's why this realm would be perfect," she clarified. "They have lots of strange things that happen there and most anyone with powers have them because they ate a special fruit. The fruits give them a specific power, so if we use magic, others may brush it off as us eating one of those fruits. So long as we don't swim with other people watching, they'll never know otherwise."

"Then we're set," the Animagus sighed fondly as he straightened up. Waving his hand to the arch, he smiled down to her. "You know how I operate it. I don't."

Her lips twitched upwards at him before she turned to the Realm Gate. Gently, she pressed her palm to the stones in a complicated pattern, occasionally asking Sirius to pick her up for the ones she couldn't reach. Each one pressed resulted in the gem glowing. Once done with the pattern, she turned to the rest of the basement and placed down a small rune on a dusty shelf.

"If we want to come back here, whether to stay or go somewhere else, this will help us," she explained, turning back to her godfather.

He held out his hand invitingly. "Best make sure we don't get separated," he offered.

Nodding in agreement, she grasped his large hand with her small fingers, her other hand gripping her trunk tightly. With a deep sigh from both, they stepped to the glowing Gate, salty wind blowing through the ratty curtains to their nostrils. They stepped into the curtains and vanished from the basement.

Here is a line!

I like Sirius, I do. It's just that, unlike in The Emerald Rose, he could have played a bigger part in her life. In that story, she was angry and hated him and he always thought he was doing what was best for her by trying to take her from Doffy. Dumb move.

Here, though, he is helping her grow and they are both going to learn new things. They will have a deeper bond.

Letting you all know this now, there will be a couple yaoi pairings. If that bothers you, do not read this story any further than this chapter. Those pairings won't pop up next chapter (maybe), but there will be mentions of previous pairings between two men. Then new pairings between two men will develop.

So there, you have your YAOI WARNING.

Let me know what you guys think and if I should pursue this idea. I'm already writing ideas, and I do not promise finishing this. But it popped into my head and you know me. I gotta share it.
