It was a stormy evening in the outskirts of Wiltshire, and it was a hard night for the family living in the manor. The reason this is a hard night is because tonight marks the 15-year-long disappearance of the youngest Malfoy.

Inside the sun room, a couple stared at a family portrait hanging over the fireplace. The portrait consisted of two adults with pale blond and black hair respectively, with the eldest male holding an identical toddler boy. The younger adult was holding a bleary-eyed infant girl in his arms with a bright grin on his face.

The black-haired male in the portrait was sitting on the couch underneath a warm blanket and leaning against his husband's shoulder, lost in a flashback of when his precious baby girl was born..

Flashback starts
Severus Prince-Malfoy was laying in a bed, exhausted but enthralled as he stared at the tiny infant in his arms. This was the product of his and Lucius's love.. a life that he carried for nine months..

Bundled in a snow-white blanket, the baby blinked open bleary emerald eyes to stare at her mother.

Lucius entered the room with a curious ten-month-old Draco in his arms.

The young child curiously eyed the baby in his "Mama's" arms. Poor thing was too young to know his actual mother, and since Severus was raising him, it only made sense to call Severus "Mama".

"Mama?" Draco cooed, noticing the new person in the room.

"Say hello to your new baby sister, Dragon. Her name is Yue Carina Prince-Malfoy," the exhausted wizard whispered before falling asleep with his daughter still cradled in his arms.

After having a house-elf take Draco back to his nursery, Lucius gently lifted his daughter up into his own arms and kissed her forehead before placing her into a bassinet next to the bed.

He smiled at his baby daughter, and hugged his mate close to his chest before finally drifting off into Morpheus's embrace.
Flashback ends

A tear ran down Severus's cheek as he thought about the baby he lost fifteen years ago. Yue, his beloved little moon, was only about two weeks old when their manor was raided by the Order of the Phoenix.

Her terrified cries haunted his memories, but he knew that as much as his heart ached, he and Lucius still had Draco to take care of. That being said, Severus never stopped loving her or praying to find her again.

Since Draco's biological mother, Narcissa Elise Black-Malfoy, had died in childbirth, Severus stepped up and helped Lucius to take care of him. Eventually, Sev started to care for the baby as his own son.

Before long, he ended up falling in love with Lucius and had a child with him. And then, just two weeks after giving birth, his child was taken away from him. It seemed that he was not allowed to be happy at all...

''I hope you know we love you, Yue.. Happy Birthday, Little Moon,'' was his last thought before crying himself into an exhausted and dreamless sleep.

Little did he know, on 4 Privet Drive in Little Whinging, Surrey, a small girl with twinkling green eyes curled into a ball while trapped in a broom closet under the stairs. ''Happy Birthday, Lia,''

15-year-old Helena 'Lia' Marie Potter dutifully finished cooking breakfast for the Dursleys. The task brought her no joy, however, as it was a chore instead of a hobby for her.

"Hey, freak!" Petunia shrieked. "Start doing the dishes! I want all your chores done by the time we get home!"

Lia, knowing better than to disobey her, meekly replied, "Yes, Aunt Petunia."

With a haughty sniff, the Dursley family finished their food and left for work and school. The child wearily sighed and got to work.

As she washed the dishes, Helena started singing an old lullaby. It felt familiar to her somehow, but couldn't remember where she heard it.

"Where the North wind meets the sea
There's a river full of memory
Sleep, my darling, safe and sound
For in this river, all is found

In her waters, deep and true
Lie the answers and a path for you
Dive down deep into her sound
But not too far or you'll be drowned

Yes, she will sing to those who'll hear
And in her song, all magic flows
But can you brave what you most fear?
Can you face what the river knows?

Where the North wind meets the sea
There's a mother full of memory
Come, my darling, homeward bound
When all is lost, then all is found"

All while she was singing, Yelihn completed her chores in a timely manner and still found time to cook herself some lunch.

Suddenly, an owl knocked on the kitchen window with a letter in it's beak. Helena giggled slightly and opened the window, allowing the bird to perch on her arm.

Taking the letter and opening it, the letter read:

"Dear Ms. Potter,
It seems that your vaults have been losing gold, even though our records state you've never made any withdrawals. This note is a Portkey and will take you to our bank. Simply say, "Carina", and you will be transported.

May your gold always flow,
Griphook"

Confused, the girl said, "Carina?", and was taken from the house with a tug at her navel.

When she arrived at the bank, Griphook was waiting for her. "Hello, Ms. Potter. As I said in the letter, someone has been draining gold from your vaults. First, place seven drops of blood onto this parchment," he instructed.

After nicking her finger on the silver knife and placing seven drops, the results shocked her.

Helena couldn't help but stare in shock. She wasn't a Potter; her real name was Yue, Draco was her brother, Snape was her mother, and Lucius Malfoy was her father.

Suddenly, a distant memory flashed in her mind.

It was Prof- her mother. He was standing in a nursery.. and there was a baby in his arms. The child, only a few days old, had wispy platinum-white hair and twinkling green eyes.

"Oh, Yue. I hope you know that I love you now and forever.. If someone took you, I won't stop looking until you're found."

Her baby self just cooed in response and dozed off.

Calming down, she stared at Griphook, and told him, "Call my family.. I want my mum."

The goblin grinned and replied, "Consider it done."

Severus stared at the note in his hand, trembling with anticipation, happiness, and relief.

"Your daughter has been found. She's waiting for you at Gringotts.

-Griphook"

Found.

She's been found.

His daughter was alive..

She was alive!

Without a second thought, he ran into the family parlor, where Lucius was sitting on a sofa with Draco napping in his lap, and handed Lucius the note.

The blonde read the note before carefully getting up, trying not to wake Draco up. The young teen had a nightmare about his younger sister being killed in front of him, and was up the rest of the night.

After a shout of "Gringotts", the family of three asked the teller that they needed to speak to Griphook.

"Follow me," was the gruff reply as they were led to the goblin manager's office. Severus knocked on the door, and after hearing, "Enter", opened the door.

Sitting in one of the chairs was a small girl with platinum white hair reaching her middle back and big, doe-like emerald green eyes.

There was no mistaking it, this was his girl.

"Yue?"

Yue looked up at the call of her name, and upon seeing her mother standing there, teared up. She tentatively took a step forward, before launching herself into Severus's arms. "Mummy, mummy!"

Draco looked at his father, who nodded and gestured him forward. Walking up slowly, so as not to frighten her, he spoke up.

"Hi, Yue.. I'm your brother, Draco.."

The child shyly peeked over her mother's shoulder before giving an adorable smile.
