16-year-old Hermione Granger grunted as she tried to get her trunk onto the train. She blinked as a girl with vibrant red hair in front of her snapped and her trunk lifted from her grasp suddenly. She looked at the girl and only saw she was the same age as herself, probably just a little younger and had long flowing hair. "You're welcome," said the girl and Hermione snapped out of her stupor.

"Th-thank you," she replied. "W-wait up!" Hermione hurried after her.

"Did I invite you along?"

"No. I-I just assumed…"

"Don't worry." Hermione gasped as the girl turned around and she saw striking, almost glowing, emerald colored eyes hidden behind thin rimmed glasses and under a star shaped scar.

"Y-you're…"

"Ooh. A fan. Always a pleasure." She took Hermione's hand and kissed the back of it. "Even though you know my name, I was still taught to introduce myself accordingly. Harriet Morningstar. At your service."

"H-Hermione Granger."

"Oh, like the Shakespeare character? Unique. And a very beautiful name."

"Th-thank you."

"Care to sit with me, Miss Granger?"

"S-sure." Harriet grinned before leading Hermione into an empty cart.


(Fifteen years ago)

Lucifer Morningstar looked at the crying baby lying on the counter in front of him and thanked… well not his father, that would be too cliché and just vindicating the old man, but whoever he could thank that Lux was closed for the day. He looked at the one who brought the child here and frowned slightly. "Why am I staring at a baby," he asked.

"Don't recognize your own daughter, Lucifer," asked Remiel as she leaned against a wall across from Lucifer.

"Daughter? I'm sure I've always been careful about that kind of thing."

"Apparently not."

"Incoming," said a voice from the window. Lucifer turned to his balcony and saw another sight he didn't expect to see. "Hi, Luci!"

"Azrael," asked Lucifer. He stared at his other sister before noticing a soul with her and looked at the woman she brought. "Lily Potter?"

"Seems your little tryst bore fruit," said Remiel. "I knew you would screw up eventually."

"There was an incident," said Azrael. "Father's Magical Community has gone through a second war. This one led by a man named Riddle. And your daughter has been marked by a Delphi descendant."

"So the Moirai have gotten involved, have they?"

"They have. Your daughter is supposed to stop Riddle when she grows older. And father has ordered Remiel not to bring her mother to the Silver City. She was to bring little Harriet here while I brought back her mother."

"Why have you done that?"

"We don't trust you to raise a child alone," said Remiel. "She'd just turn into a smaller, female version of you."

"And as the destined Master of Death, that wouldn't be good," said Azrael.

"I thought the Peverell's were extinct," mused Lucifer.

"They survived through the Potter's. And James Potter, Lily's husband who she told of her affair with you, Blood Adopted Harriet without a second thought. They're love and bond was that strong." Lucifer looked at the baby, Harriet, and saw an unusual scar on her forehead.

"Oh. Look at that. A regular Morningstar."

"Shut it," said Remiel. "It's from a curse that tried to kill her. Poor bastard didn't know mortal magic doesn't work on Nephilim. Especially not Arch-Nephilim." Remiel looked at the child. "The fact that Father doesn't want me killing this abomination…"

"Means you should love her, Remi," said Azrael with a smile. "She is your niece, after all. And she could do to learn from her huntress auntie if she's going to bring Riddle to Hell." Remiel smiled at Lucifer before snapping and bringing Lily Potter to physical form and lying the sleeping woman on Lucifer's oversized bed.

"And why on Earth should I do what dear old Dad says," said Lucifer.

"Because unlike any other thing Dad's wanted you to do, he's not trying to teach you a lesson. He's looking out for his granddaughter. The First Nephilim born in millennia and this one blessed by the Moirai and Auntie? She's important. And given how things are in the British Wizarding Society, a bit of rebellion will go a long way. And I believe that's your area of expertise." Azrael picked up the child and handed her to Lucifer who held the baby at arm's length. "I'll be back, little Hari! If only because I want to see my niece! Bye, Luci!" Azrael waved as she and Remiel grew their wings and flew out of Lux, leaving a perplexed and annoyed Lucifer alone with an unconscious woman and her baby who desperately needed a diaper change.

"Bloody Hell…" He looked around before carrying the baby to the foyer. "Maze!"


(Present Day)

Harriet looked up and smiled as the door to the car opened. "Lovely," she said, spotting the two girls standing in the doorway. "Two more fetching beauties to speak with." The girls, a redhead and a dirty blonde, blushed at the comment, and at the girl who said it. "And a fellow redhead? I must be lucky." She reached out her hand to them and the redhead took it. "Harriet Morningstar. At your service."

"Morningstar," asked the blonde. "You mean like the…"

"The Devil. Of course." Harriet smiled before kissing the girl's hand with a wink. "And who might you two lovelies be?"

"S-Susan Bones," said the redhead.

"H-Hannah Abbot," said the blonde.

"Susan and Hannah. Pretty names for very pretty girls." Again, both girls blushed as Harriet gestured to the other girl in the car. "This is Hermione Granger, my new acquaintance. Say hello, 'Mione."

"Hello," said the bushy-haired girl.

"Come join us, ladies. Two's company, but four's a party." She snapped and the girls' trunks floated up to the compartments above Harriet's head as she flashed a smile at the two. Susan and Hannah exchanged a look before entering the car and sitting down. "Now, judging by your ages, I'd say you're all first years as well?"

"We are," said Susan.

"Lovely that. Wouldn't want to start the year without knowing someone."

"Is your family name really Morningstar," asked Hannah.

"It is. Dear old Dad came up with it himself eons ago."

"Your dad just started a family name all on his own?"

"Well it's not like it was hard." Harriet rolled her eyes.

"Do you not know who she is," asked Hermione. Hannah and Susan looked at each other before looking at her.

"Not really," said Susan. "Who is she?"

"Only the most famous musician in the world! She's sold out concerts in America since she was 6!"

"That's my dad's talent rubbing off on me," said Harriet with a smirk.

"You can play instruments," asked Hannah.

"Piano, like my dad, violin, guitar, drums, I can even sing. Though, that's reserved for private sessions." She winked at the girls who blushed at the implications before shaking their head as the car opened again.

"I heard Harriet Potter was in this car," said a loud blonde boy. "Is she?"

"No Potter here, handsome. Best look in another car." She waved him off and the boy glared at her before stepping into the car.

"Do you have any idea who I am?!"

"A loud obnoxious 'Pure-Blood' who doesn't know anything about manners? Look, I'm having a conversation with my acquaintances, kindly fuck off and leave us alone." She flicked her hand forward and the boy was thrown backwards into the two boys who had followed him to the car. She snapped and the car closed before she crossed one leg over the other and resuming her smile at the girls. "Now then, where were we?"

"You were bragging about your musical talents," said a voice at the window. Harriet gasped as the other three girls jumped. Harriet turned to the window and smiled.

"Aunt Remi!" She hurried to the window and hugged the stern woman who glared slightly but didn't pull away. "What are you doing here?!"

"You forgot this." Remi handed her a long item bundled in cloth before sighing as the girl hugged it. "I should've just left it at Lux."

"Aw, you wouldn't want to see me sad, Auntie!" Harriet smiled brightly at Remi who sighed before moving away from the window, allowing the other three girls as well as the occupants in the other cars to see the winged woman glaring at the car.

"Don't lose it!"

"Bye, Auntie!" Harriet waved as Remi rolled her eyes before flying up to the clouds. Harriet hugged the cloth covered object with affection as the girls stared at her.

"Are you part Veela," asked Susan. "Would explain why I'm all bo…"She gasped and covered her mouth as she blushed.

"I suppose you could label me like that. Why?" Harriet leaned in close to the girl, darkening the blush. "Have a thing for Veela, do we?" Susan blushed even more before turning away, opting not to speak as Harriet smirked. She turned to the other two who blushed at the look in her eyes. "And you two?" Hermione gulped before reaching into her bag and pulling out a book while Hannah found interest in her skirt. It was as Harriet sat back down and crossed her legs again that Susan turned back and looked at the bundle in the flirtatious girl's arms.

"What is that?"

"What? This? It's Moa."

"Moa," asked Hermione, looking up from her book.

"Magical Omni-Apparatus. M.O.A. Moa."

"Magical what," asked Hannah.

"A gift from my Auntie Remi. It's a magical device made of a malleable metal and imbued with pure magic. It becomes everything and anything I could ever want. Though it can't turn into food, drink, or, Hell forbids, a loyal servant. Could do with my own Mazekin. Would save me some serious energy for menial tasks."

"Mazekin," asked Susan.

"Oh, just a demon Dad brought from Hell. Does his every whim. Well, sort of. She's been a bit bitchy lately."

"You should really watch your language, Miss Morningstar," said Hermione. "It's very unladylike."

"You remind me of my mother and stick-in-the-mud Uncle Amen. Always wanting me to behave a certain way. If you weren't cute, I'd be berating you, 'Mione." Hermione blushed bright and turned away, muttering under her breath as the door opened once more. Harriet looked up and her eyes met with two pairs of cold blue and warm green eyes behind two more girls. "Well. Now it's an orgy, isn't it?" The raven-haired newcomer with green eyes smirked.

"Oh, I knew this was the right car," she exclaimed. Her companion sighed and face palmed as the other girls in the car blushed like mad.

"Merlin there's two of you," she muttered.

"Do I detect an Icy Queen in need of melting," asked Harriet with a grin.

"More like permafrost," muttered the raven-haired girl, earning a smack from her companion.

"Ooh. She's kinky, too? I am a lucky girl." This earned a smirk and blush and scowl from the new girls, respectively.

"I like her, Daphne," said the first girl.

"You would," said the blonde, Daphne.

"There's room for two more in here," said Harriet with a grin. "Might be a tight fit but, I'm sure one of you wouldn't mind sitting in my lap." The raven-haired girl giggled before turning to Daphne who rolled her eyes and closed the door to the car. Harriet pouted slightly before shrugging.

"You're a shameless flirt," exclaimed Susan.

"Guilty as charged, Love. I am my father's daughter, after all." Susan and Hannah looked at Hermione who cleared her blush as she finally wrapped her head around Harriet's suggestive comments.

"Harriet's father, Lucifer Morningstar, is known as being the flirtatious and highly influential owner of Lux, a popular club in Los Angeles," said Hermione.

"Dear old Dad truly made a reputation for himself. And is known to be a very generous host to some lucky women, and the occasional man, at Lux."

"Isn't he married to your mum," asked Hannah.

"Technically. Though it's more of an open marriage. Hell, Mum's been known to join Dad on occasion. When she's not busy, that is." Harriet pulled out Moa and had it morph into the shape of a violin before taking a more wooden texture. As a piece of the device broke off into a bow without any hair. The girls looked at her questioningly before she started drawing the bow across the wire on the violin. They froze as a beautiful sound came from the instrument and Harriet began to idly play.


In the next car over, Daphne and her best friend, Tracey, sat beside Pansy Parkinson and Millicent Bulstrode as they started hearing the music playing from the car Tracey and Daphne just left. Tracey closed her eyes with a smile and listened to the music as Daphne blushed lightly as she heard the song that was playing. Pansy and Millicent listened and both exchanged smiles as they heard it. Tracey snuck a glance at Daphne and nudged her as she saw the blush on her friend's face. Daphne scowled at her before schooling her expression, trying to ignore the song as it played out its course. Though she couldn't help but feel her heart flutter as whoever was playing the violin in the other car, she presumed Tracey's counterpart, ended the song with a flourish worthy of a professional.


"How," exclaimed Hermione after she regained her sense of awareness. "How did you make any sound?!"

"Thestral hair bow," said Harriet with a grin. "Because of the nature of Moa, it can morph into almost anything. Provided it has a memory of the composition of said item."

"But that's impossible!"

"Call it heavenly magic, Love. There are tiers that no one else can achieve. Well, not unless you're my family, that is."


A few hours later, Harriet felt they were close to their destination and glanced at the girls with a smirk. She snapped and the girls blushed as they felt their clothes swap to their uniforms. Harriet smirked as they instinctively covered themselves after the fact. "Oh, I'm going to love it here if you three are just the appetizers."

"I feel violated," muttered Hannah.

"Oh, believe me." She moved close to the blonde girl and cupped her cheek with the crook of her finger. "It only gets better from here." Hannah's face resembled a tomato as Susan blushed and gently pushed Harriet from her best friend.

"Thank you for the quick change," she muttered. "And for the song. Can you please tone down the flirting? I don't think our hearts can handle anymore of it."

"Very well. I'll simmer down, for now. But no promises for later, Beauty." She winked at Susan who cleared her throat and settled her blushing before nodding.

"Thank you." Harriet flashed another smile before snapping and Moa transformed into a silver bracelet in the form of a snake on her left wrist. She smirked and rubbed its head before turning to the girls.

"Right then. Need help with your trunks?"

"If it's not too much of a bother," said Hermione. Harriet smirked.

"For you, Love? Of course not." She winked as Hermione blushed before snapping and making the trunks float behind them as they pulled up to Hogsmeade Station and climbed off the train. She set them down in a neat stack before snapping once more and seeing two more trunks land beside them. She turned around and winked at Daphne and Tracey who scowled and winked back respectively. Tracey made her way over and grinned at her. "Hello, Lovely."

"We haven't been properly introduced," she said. She held out her hand. "My name is Tracey Davis." Harriet smiled and took it before kissing her hand.

"Harriet Morningstar, at your service."

"The good kind, I hope."

"Ooh, cheeky. I think I'll like you."

"Then here's to a beautiful friendship. And hopefully more down the line."

"Ooh, flirt."

"If you two are quite done," said Daphne. "We should get moving."

"Is she always…"

"An Ice Queen," asked Tracey as her best friend walked away. "Sadly. It's because she needs to keep her emotions in check, especially if she's gonna be in Slytherin with people like Malfoy. He can infuriate even the most practiced Occlumency users."

"Let me guess. Blonde, British, slightly handsome, full of himself?"

"Oh, you've met!"

"Not a fan."

"Most aren't. He's a ponce."

"I can tell." Harriet put her arm around Tracey's shoulders as they made their way to the docks. "So, Lovely. Did you enjoy my song, earlier?"

"So that was you! Very nice!"

"Thank you, thank you! I aim to please!"

"She's world famous, you know," exclaimed Hermione behind them. Tracey jumped and turned around as Harriet smiled. "She plays concerts all around the world!"

"Really," asked Daphne as she looked back at them out of curiosity.

"It's true," said Harriet as she met the girl's gaze. "I'm a teen sweetheart to all my fans. But I can be naughty when it counts." Daphne blushed before looking forward. She smirked alongside Tracey who caught sight of it as well.

"I'm going to love you," sighed Tracey with a grin.

"I'll make damn sure of it too." Tracey grinned before they continued to the boats and Harriet grinned as she plopped down in front of Daphne as Tracey took the spot beside the blonde. Harriet waved as Daphne scowled at her. She looked up as Hermione climbed into the boat next to her and smiled as the bushy-haired girl blushed lightly. "Well this is cozy." She looked up as another girl, this one a platinum blonde, sat in her lap. Harriet grinned. "And this is just delightful. Hello~" The girl looked back at her with a slightly spaced look.

"Hello," she said. "I figured you wouldn't mind."

"Not at all. And if you fall out, I'll be sure to fish you out and keep you dry."

"Thank you." Harriet quirked an eyebrow and exchanged a look with Tracey who snickered slightly as the girl showed no signs of embarrassment.

"Something you care to share?"

"Not at the moment," said Tracey with a grin.

"This is Luna Lovegood," said Daphne. "She doesn't react normally to things. In primary, people often called her Loony Lovegood."

"That's horrible," exclaimed Hermione.

"Is it," asked Luna.

"It's a matter of perspective," said Harriet with a grin.

"Oh no," muttered Hermione, getting a feeling of what was coming.

"Loony people tend to be very creative in bed." Hermione blushed lightly.

"I knew that was coming…" Luna tilted her head slightly as Daphne shook her head and Tracey grinned.

"I thought you've only met her today," said Daphne.

"The entire train ride felt like years. I feel like I already have a grasp what Harriet is going to be like."

"Besties for life," sand Harriet. Daphne facepalmed as Tracey grinned.

"Hah," she exclaimed. "I knew someone had the same philosophy!"

"I'm going to hate the next four years, aren't I," muttered Daphne.

"Oh, by the end of this year you're going to love being around her," said Luna. Harriet gasped and smiled.

"You're a Delphi," she exclaimed.

"A what," asked Hermione.

"Only the best people ever!" She hugged Luna with a grin. "It's official, I'm keeping you!"

"Keep her?!"

"Ok," said Luna.

"Luna, you can't just agree to that!"

"But she's heavenly." Harriet grinned and hugged the girl closer.

"Settles it, she's mine," exclaimed Harriet with a grin. "And to answer your question, a Delphi is a descendant of the Ancient Greek Oracle! They've inherited the Oracle's Gift of Prophecy and are exceptionally rare since granddad's followers hunted them down out of fear and their whole 'False Prophet' thing. Honestly, you'll never find a bigger bunch of paranoid hypocrites on Earth."

"Thank Merlin," muttered Daphne. "We're finally departing from the docks. I swear, this is the most tedious Hogwarts tradition they should've done away with when they changed the age requirements for the school."

"Why did they do that," asked Hermione.

"It's because the DADA teacher keeps getting replaced," said Harriet. "And it's been getting more and more violent. A lot of parents were getting worried about their younger children getting put in potential danger so they whined to the Ministry and they strong-armed Dumbledore into adjusting the years for new students." She looked up at the stars. "Not like it makes a difference when compared to back home anyways."

"Are you talking about Ilvermorny," said Tracey.

"That I am. Ilvermorny has taken Hogwarts former spot as greatest magical school in the world."

"So why not go there," asked Daphne.

"Don't really have a choice in the matter."

"Her grandfather is forcing her to go," said Luna.

"That he is. Once a prat, always a prat."

"Who is your grandfather," asked Hermione. "I've never read anywhere that your father ever mentions him."

"He mentions him all the time. And every time he mentions his name."

"You actually believe the spiel he gives about actually being the devil? Aren't you a bit old for that nonsense?"

"Nonsense? My dad's been nothing if not honest about who he is since he first came to Earth from Hell. You saw my aunt Remi. Didn't something seem different about her? Veela often change their arms to wings to fly. But Auntie Remi had them on her back. Sound familiar?"

"I'm sure there are examples of…"

"She's an angel," said Luna. "And Harriet is a Nephilim."

"Arch-Nephilim. Please get it right. Honestly. Daughter of the Morningstar and no one seems to get it right."

"Sorry."

"It's fine. Though why they remember to say Archangel when my family is brought up is a bit of a pain." Harriet sighed dramatically before shaking her head. "Even Dad seems to forget at times, and he's been raising me for years. Well, I say raising but it's more Mum making the decisions. Dad just spoils me rotten and sometimes exploits my talents for Lux. And occasionally teaches me how to better be like him. Charismatic, intuitive…" She winked at Tracey. "Flexible."

"Tease," said the brunette with a smirk.

"I'm this close to pushing you both out of the boat," said Daphne.

"Can't wait to get me wet, can you," chuckled Harriet. Daphne and Hermione blushed brightly before the former turned away and Hermione buried her nose in her book before she shook her head.

"Wait. It can't be true," she said. "For you to be a Nephilim that would mean that…"

"God, Dad, Heaven and Hell? All real. And Purgatory. But that hasn't been managed in centuries."

"So, Lucifer Morningstar is literally…"

"The Morningstar, yes. We've only been saying it for years."

"We're only protected from seeing their divinity because our magic is a direct gift from Hecate. It's divine in its own right," said Luna. "And Yahweh took the credit…"

"As usual. Grandpa tends to be a bit of a thief. And also tends to be a tad self-righteous." Hermione jumped as thunder sounded as clouds started rolling in. "It's true, Geezer!"

"Suddenly I'm having second thoughts being around you," said Hermione.

"Too late. We're gonna be joined at the hip, I just know it."

"Joined at the…?!" Harriet smirked as Hermione's face resembled a tomato.

"Ooh. Someone's got a dirty mind, haven't they?"

"She's not the only one," said Tracey as she smirked at her best friend who mirrored Hermione.

"Shut up," said Daphne. "Or I'm disowning you."

"You won't. I'm your only friend."

"Oh, we're going to get along just fine," exclaimed Harriet with a grin.

"Agreed!"


As the boats sailed to the castle, a figure watched them from above. Lucifer Morningstar crossed his arms as he watched his daughter head for her new school and sighed as he heard a flapping of wings behind him. "Yes," he said, turning to face the dark-skinned man behind him. "What is it, Amenadiel?"

"You shouldn't worry, Lucy," said the other angel. "She'll be fine."

"I know that. But you know better than I do that a father worries. Especially with Riddle being here."

"Hari can handle it. Besides, I'll be here for her."

"Oh yes, because that makes it so much better." Lucifer looked at the castle. "And Riddle isn't the one I'm worried about. It's her headmaster. I met the man when he personally handed her the acceptance letter. He felt like our dear older brother. Lies and fear."

"That's why we influenced the Wizengamot, remember? Making sure Hari was older than the previous First Year age and definitely smarter thanks to Lily. She'll see through the manipulations Albus may use against her. He won't stop until her prophecy is fulfilled to his specifications. So we worked against anything he might try to use against her."

"Covered every single trick did you? That's believable."

"She'll be fine, Lucy. You just gotta have faith in her and in me."

"Her I do have faith in. You? Not so much. You really haven't adapted to life on Earth so well, brother."

"I think I've adjusted well. Dan seemed to think so."

"Who?"

"Daniel Espinoza? Chloe's ex-husband?"

"Oh, Detective Douche. That's… reassuring."

"Just stop worrying, brother. It's not like you can watch over her at school. There's not even a position open." Amenadiel chuckled. "Well, unless you find a way to deal with Riddle and take the Defense position. Lucifer perked up slightly and turned to his brother.

"Now there's an idea." Amenadiel turned to Lucifer.

"Luci, no."

"I'll just take the soul fragment now and become the Defense Against the Dark Arts professor. Maze and Lily can take care of Lux, Detective Decker is annoyed with me currently. It all works out!" Lucifer pat his brother on the shoulder. "Thanks for the suggestion, Amenadiel!" Lucifer flew down to the castle and Amenadiel blinked before rushing after his brother.


Down at the lake, Hari noticed a couple of flashes of white and looked up, seeing two figures flying for the castle ahead of them. 'Uncle Amen lasted longer than I thought before giving dear old Dad an idea,' she thought to herself. She smirked to herself as she felt a soul fragment enter Hell a few moments later and leaned back in her spot in the boat. 'One less thing to worry about. Now I can focus on the lovelies in the school! Harem Queen time!'


(Author's Notes)

So here's an idea I had a while back I hadn't really felt like uploading until now. Bit of a fun thought I had when watching the final season of Lucifer with my mom. What if the Devil's Daughter was Harriet Potter? And yes, Aurora will still be born. It wouldn't be right not to include her in this, since she's integral to where Lucifer ends up at the end of the show. I haven't read the comics, so this story will be purely based on the show, sorry to the purists. If any of you are regular readers of mine, and wondering why I went silent, again, a week after I uploaded the first chapter of For Hearts and Souls, my grandmother passed away. I really haven't been in a good mindset since then and am slowly trying to work out a routine to get my mind back in working order. I can't promise regular updates, I can promise to have old and new ideas coming eventually. Until next time, Y'all!
