Daughters of Immortal Blood

Summary:

As the daughter of Damon Salvatore and Elena Gilbert, Stephanie was born into legend — the world’s first natural-born vampire and the last echo of a doppelgänger line.

At the Salvatore School she tries to figure out who she’s supposed to be… until Hope Mikaelson walks into her life.

Because sometimes the universe creates impossible people for one reason:

To find their epic love.

Chapter 1: The Salvatore Legacy

Summary:

They thought the cure ended the story of vampires.

But legends have a way of rewriting themselves.

Born from doppelgänger blood and dormant vampirism, Stephanie Salvatore is the first of her kind—a living vampire with a destiny written long before she was born. And somewhere out there, another supernatural soul is tied to hers.

Chapter Text

The house was quiet in a way it hadn’t been in years.

Not the heavy, grief-stricken silence that had hung over Mystic Falls after the funeral—but something softer. Gentle. The kind that came from a life slowly starting again.

Elena sat curled into the corner of the couch, a blanket draped loosely over her legs. The late afternoon sun spilled through the windows, painting the living room gold. In her hands was a small folded piece of paper—the doctor’s report she had read at least a dozen times already.

Across the room, Damon leaned against the kitchen counter, watching her with a mixture of curiosity and nervousness he would never admit out loud.

“Alright,” he said finally, breaking the silence. “You’ve been staring at that paper like it’s about to sprout legs and run away.”

Elena looked up, the corner of her mouth lifting.

“It’s still real,” she said softly.

Damon pushed off the counter and walked toward her, slower than usual. Careful. Like if he moved too fast, the moment might shatter.

“Let me guess,” he said, dropping onto the couch beside her. “Doctor says you’re stuck with me for at least eighteen more years.”

Elena rolled her eyes affectionately and handed him the paper.

Damon skimmed it lazily at first… until his expression shifted.

His eyebrows shot up.

“Well,” he muttered. “That’s… definitely new.”

Elena watched him carefully. “You okay?”

Damon looked up at her, something unusually soft in his eyes.

“A girl,” he said.

Elena nodded.

“A girl,” she repeated.

For a moment, Damon didn’t speak. His thumb rubbed absentmindedly over the edge of the paper.

“God help her,” he said after a beat. “She’s got our DNA.”

Elena laughed quietly, leaning her head against his shoulder.

“She’ll survive.”

Damon wrapped an arm around her automatically, pulling her closer.

Then his usual smirk returned.

“So,” he said. “What are we naming this tiny future menace?”

Elena hummed thoughtfully.

“I don’t know yet.”

“Please tell me you’re not about to suggest something like Moonbeam or Starflower.”

She nudged him with her elbow.

“I would never.”

Damon narrowed his eyes suspiciously.

Elena pulled her knees closer under the blanket, thinking.

“I’ve been making a list,” she admitted.

“Oh good,” Damon sighed dramatically. “There’s a list.”

“Don’t be dramatic.”

“I’m Damon Salvatore. Dramatic is the brand.”

Elena grabbed a small notebook from the coffee table and flipped it open.

“Okay,” she said. “First option: Caroline.”

Damon blinked.

“…you’re naming our child after the control freak blonde?”

“She’d be honored!”

“She’d start planning the kid’s wedding at age four.”

Elena bit back a smile and crossed it out.

“Okay… Jenna?”

Damon’s expression softened briefly.

“Not bad,” he admitted.

“But?” Elena asked.

“But if she gets Aunt Jenna’s cooking skills we’re all doomed.”

Elena laughed again.

She flipped the page.

“What about—”

Her voice trailed off.

Damon noticed immediately.

“What?”

Elena stared down at the page, her fingers gently tracing the name written there.

The room seemed to grow quieter.

“Stefan…” she murmured.

Damon’s expression changed.

Not pain exactly.

Something deeper.

He leaned forward slightly.

“You want to name our daughter Stefan?”

Elena shook her head softly.

“No.”

She looked up at him, eyes warm but a little emotional.

“What about Stephanie?”

Damon went still.

For a moment, he didn’t say anything.

His gaze drifted toward the window, toward the fading sunlight.

Stefan had always liked the sunlight.

Typical hero.

Elena watched him carefully.

“We don’t have to,” she said quietly. “I just thought—”

Damon interrupted her.

“…Stephanie.”

He leaned back into the couch, testing the name out loud.

“Stephanie Salvatore.”

Elena smiled faintly.

Damon rubbed the back of his neck.

“You know he’d hate that, right?”

Elena tilted her head. “Why?”

“Because it honors him,” Damon said with a small huff. “And Stefan was allergic to being honored.”

Elena laughed softly.

“Maybe,” she said. “But I think he’d secretly love it.”

Damon was quiet again.

Then he looked down at Elena’s stomach.

Still barely noticeable.

Still the beginning of everything.

“Well,” he muttered.

Elena raised an eyebrow.

“Well what?”

Damon smirked faintly.

“If she gets Stefan’s heart and your stubbornness…” he said, “the world’s gonna be in serious trouble.”

Elena rested her hand over his.

“So… you like it?”

Damon exhaled slowly.

Then nodded.

“Yeah,” he said quietly.

A small smile tugged at his lips.

“Stephanie.”

 


 

The Salvatore-Gilbert household had learned a new kind of quiet.

Not the heavy stillness of grief, not the cautious calm of rebuilding—but the gentle, fragile quiet of a sleeping baby.

Stephanie Salvatore lay in her crib near the couch, tiny fingers curled around the edge of a soft blanket. Sunlight streamed through the tall windows, catching in the dark wisps of hair on her head.

Elena stood nearby, holding a small jar of baby food and a spoon.

“Okay,” she murmured softly. “Just a little more.”

Damon lounged on the couch, watching with mild amusement.

“I’m just saying,” he said, “she’s my daughter. She’s obviously already developed superior taste.”

Elena shot him a look.

“She’s three months old.”

“Exactly. A prodigy.”

Elena rolled her eyes and gently offered the spoon toward Stephanie.

The baby wrinkled her tiny nose.

Then came the sound Elena had been hearing for the past two days.

Stephanie gagged.

Not just the typical baby fussing either. Her entire little body tensed as she tried to swallow the food before immediately coughing it back up.

Elena’s smile faded.

“Oh—okay, okay,” she said quickly, setting the spoon aside and lifting her daughter into her arms. “It’s okay, baby.”

Stephanie whimpered weakly.

Damon sat up.

“You said this happened yesterday too?”

Elena nodded, worry already creeping into her voice.

“And the day before.”

Stephanie pushed weakly against Elena’s chest, her face scrunching in discomfort.

Elena tried again with the spoon.

Stephanie gagged harder this time.

Within seconds she was coughing and crying, tiny body trembling.

Elena’s heart dropped.

“No, no, no…” she whispered.

Damon was already on his feet.

“Elena—”

“She’s not keeping anything down,” Elena said, voice shaking. “Formula, baby food, nothing.”

Stephanie whimpered again, weak and exhausted.

Damon frowned.

“Maybe she’s just sick.”

Elena shook her head immediately.

“No. This isn’t sick.”

She held Stephanie tighter, panic building in her chest.

“She’s not just refusing food, Damon. Her body’s rejecting it.”

As if proving her point, Stephanie let out another small cry before going limp with exhaustion against Elena’s shoulder.

Elena felt the terrifying lightness of her daughter’s weight.

Her breath caught.

“Oh my god…”

Damon’s expression shifted from confusion to concern.

“Elena?”

“She’s losing weight,” Elena whispered. “Damon, she’s barely eaten in two days.”

Damon ran a hand through his hair.

“Okay,” he said, trying to stay calm. “We’ll call the doctor—”

“No.”

Elena looked up at him, fear clear in her eyes.

“We’re not calling a doctor.”

Damon blinked.

“Elena—”

“She’s our daughter,” Elena said, voice tight. “Do you really want doctors running tests on a Salvatore baby in Mystic Falls?”

Damon paused.

Fair point.

Elena swallowed hard.

“I’m calling Bonnie.”

 


 

Bonnie arrived less than an hour later.

She barely had time to step inside before Elena rushed toward her with Stephanie in her arms.

“Bonnie, something’s wrong.”

Bonnie immediately softened when she saw the baby.

“Hey, little one,” she said gently.

But Elena’s anxious expression wiped the smile from her face.

“What’s happening?”

“She can’t eat,” Elena said quickly. “Anything. Her body just rejects it.”

Bonnie frowned.

“How long?”

“Two days.”

Damon leaned against the table nearby, arms crossed tightly.

“And before you ask, yes. We tried everything.”

Bonnie studied Stephanie carefully.

The baby looked pale.

Too pale.

Bonnie’s brows knit together.

“Okay,” she said softly. “Let me try something.”

Elena nodded quickly.

Bonnie pulled a small cloth from her bag and laid it across the table. Then she took a tiny needle from her spell kit.

Elena hesitated.

“Is that safe?”

“It’s just a drop of blood,” Bonnie assured her gently.

Elena reluctantly placed Stephanie on the table.

Bonnie pricked the baby’s tiny finger.

Stephanie let out a small cry.

Elena immediately took her hand.

“I know, sweetheart. I know.”

A single drop of blood fell onto the cloth.

Bonnie began murmuring softly under her breath, hands hovering over the drop as faint energy flickered through the room.

The blood shimmered slightly.

Bonnie’s eyes narrowed.

Then widened.

“…That’s weird.”

Damon raised an eyebrow.

Weird isn’t exactly comforting, Bon.”

Bonnie leaned closer, focusing harder.

The blood reacted again.

Darker.

Alive with something.

Her expression slowly shifted from confusion… to realization.

“Oh.”

Elena’s stomach dropped.

“What? Bonnie, what is it?”

Bonnie looked up.

“Stephanie’s blood… it’s supernatural.”

Damon straightened.

“What?”

Bonnie gestured to the cloth.

“There are traces of vampirism in it.”

The room went still.

Elena blinked.

“…That’s not possible.”

Damon let out a short laugh.

“Yeah, because last time I checked, both of us were cured.”

Bonnie nodded slowly.

“Exactly.”

She looked back at the blood.

“But it’s not full vampirism. It’s… partial. Like it’s only half there.”

Damon frowned.

“Okay, explain how that works.”

Bonnie thought for a moment.

“Maybe the cure didn’t erase your vampirism,” she said slowly. “Maybe it just suppressed it.”

Damon’s brow furrowed.

“You’re saying it went dormant?”

Bonnie nodded.

“And somehow… it passed to Stephanie.”

Elena looked down at her daughter, heart racing.

“So what does that mean for her?”

Bonnie exhaled slowly.

“It means her body might not be able to process normal food.”

Damon’s eyes widened slightly.

“…You’re kidding.”

Bonnie looked between them.

“Try blood.”

Elena’s head snapped up.

“Bonnie—”

“Just try,” she said gently.

Damon disappeared into the kitchen and returned with a small container.

Animal blood.

Something left over from Stefan's stash that Damon never got rid of.

Elena hesitated before dipping a small spoon into it.

Stephanie squirmed weakly in her arms.

“Okay,” Elena whispered. “Just a little.”

She brought the spoon to Stephanie’s lips.

The baby drank.

For a moment, everything seemed fine.

Then—

Stephanie gagged again.

Elena’s heart sank.

“It’s not working.”

Damon ran a hand through his hair.

“Well that’s fantastic.”

Bonnie frowned.

“Try human blood.”

Both of them stared at her.

“You’re serious?” Damon asked.

Bonnie nodded.

Elena hesitated.

Then Damon sighed dramatically.

“Fine.”

He grabbed a glass from the counter and without hesitation cut into his wrist.

Blood filled the glass quickly.

Elena carefully dipped the spoon again.

She held her breath as she offered it to Stephanie.

The baby drank.

No gagging.

No coughing.

Stephanie swallowed.

Then immediately leaned forward for more.

Elena froze.

“Oh my god…”

Stephanie drank again, tiny hands gripping Elena’s shirt.

Within seconds, the color began returning to her cheeks.

Her small body relaxed.

For the first time in two days, Stephanie looked… satisfied.

Damon stared.

“Well,” he muttered.

Bonnie exhaled slowly.

“That answers that.”

Elena held her daughter tightly, relief flooding through her.

“She’s okay…”

Bonnie nodded reassuringly.

“She will be.”

Damon leaned back against the counter, still processing.

“So let me get this straight.”

He gestured toward the baby.

“Our daughter is… what, exactly?”

Bonnie shook her head slightly.

“I don’t know yet.”

She looked at Stephanie thoughtfully.

“But I’ll find out.”

Elena looked up.

“You will?”

Bonnie nodded.

“I’ll do some research. There has to be something in some legend about supernatural inheritance.”

Damon crossed his arms again.

“And if there isn’t?”

Bonnie gave him a confident smile.

“Then we’ll figure it out anyway.”

Stephanie let out a small contented sound in Elena’s arms.

Elena kissed the top of her daughter’s head.

“We will,” she whispered.

 


 

Three weeks had passed since the night everything changed.

The house had settled into a strange new routine.

Blood instead of formula.

Careful monitoring.

A lot of nervous glances between Elena and Damon.

But overall… Stephanie was thriving.

Elena stood near the crib in the living room, gently bouncing her daughter in her arms. Stephanie giggled—a bright, happy sound that filled the room.

Damon leaned against the doorway watching them, arms crossed.

“Okay,” he said slowly. “Either we accidentally created the world’s happiest vampire baby… or something weird is going on.”

Elena raised an eyebrow.

“In Mystic Falls? Weird? Impossible.”

Damon gestured toward the baby.

“She’s supposed to be four months old.”

Elena sighed softly.

“She is four months old.”

Damon tilted his head.

“Then explain why she’s the size of a six-month-old.”

Elena looked down at Stephanie.

He wasn’t wrong.

It had started subtly.

A little taller.

A little heavier.

But the changes had become impossible to ignore over the last few days.

Stephanie’s development was moving… fast.

Too fast.

Elena swallowed.

“Maybe we’re imagining it.”

Damon snorted.

“Yes, Elena. Because babies normally grow like they’re on supernatural steroids.”

Before Elena could respond—

The front door opened.

Bonnie stepped inside.

Elena’s eyes immediately lit up with relief.

“Bonnie!”

Bonnie smiled warmly.

“Hey.”

Damon straightened.

“Please tell me you found something.”

Bonnie closed the door behind her and took a slow breath.

“…I did.”

The tone in her voice made Elena’s stomach tighten.

She gently placed Stephanie in her crib before turning back to Bonnie.

“And?”

Bonnie glanced toward the baby, who was happily chewing on the edge of her blanket.

“I talked to Valerie,” Bonnie said.

Damon frowned slightly.

“Stefan’s heretic ex-girlfriend Valerie?”

Bonnie nodded.

“She’s spent the last couple of years researching supernatural bloodlines. If anyone would know something about this, it’d be her.”

Elena crossed her arms nervously.

“What did she say?”

Bonnie hesitated.

“There’s… a legend.”

Damon groaned immediately.

“Oh good. I love legends. They’re always fun.”

Bonnie ignored him.

“It describes the eventual existence of a very specific supernatural creature.”

Elena’s heart started racing.

“What kind of creature?”

Bonnie looked at Stephanie again.

“A vampire… doppelgänger hybrid.”

Silence filled the room.

Damon blinked.

“…Come again?”

Bonnie continued carefully.

“The legend calls it a natural-born vampire. A being that is technically both alive and dead.”

Elena’s breath caught.

Bonnie folded her hands together.

“The theory is that the blood of a doppelgänger—like yours, Elena—creates the conditions for the dormant vampirism of a cured vampire to pass to their child.”

Damon ran a hand through his hair.

“So the cure didn’t erase my vampirism.”

Bonnie shook her head.

“No. It just made it dormant.”

Elena glanced toward Stephanie.

“And she inherited it.”

Bonnie nodded.

“But not like normal vampires.”

She stepped closer to the crib.

“They’re alive. They breathe, their hearts beat, they grow up… they can even have children someday.”

Damon muttered under his breath.

“Great. Our family line is officially cursed.”

Bonnie continued.

“They’re stronger than normal vampires eventually. The legend says they represent the next evolution of vampirekind.”

Elena swallowed.

“What about the feeding?”

“They can only drink human blood,” Bonnie explained. “Animal blood doesn’t sustain them.”

Damon shrugged.

“Well, that explains that.”

Bonnie continued listing things off quietly.

“They don’t need invitations to enter homes.”

Elena’s eyebrows lifted.

“Because she’s technically alive?”

Bonnie nodded.

“And according to the legend, they’re extremely difficult to kill.”

Damon looked intrigued now.

“How difficult?”

Bonnie’s expression turned serious.

“The only ways are either through a very specific kind of witch… or if they’re staked during their first death.”

Elena frowned.

“First death?”

Bonnie nodded.

“When they eventually die the first time, their vampirism activates fully.”

Damon raised an eyebrow.

“And if they’re not staked?”

Bonnie met his gaze.

“Then their vampire blood keeps the human side alive permanently.”

The room fell quiet again.

Damon whistled softly.

“Okay. That’s insane.”

Bonnie nodded.

“And that’s not even the strangest part.”

Elena looked uneasy.

“What could possibly be stranger than that?”

Bonnie took a breath.

“The legend says the hybrid is born with a sort of supernatural soulmate link.”

Damon’s smirk returned immediately.

“Oh great. Destiny.”

Bonnie ignored the sarcasm.

“They’re supposedly linked to another supernatural being somewhere in the world. Someone they’re meant to find.”

Elena’s expression shifted slightly.

Bonnie continued.

“And their aging is accelerated until they reach the same age as that person.”

Elena blinked.

“…What?”

Bonnie nodded.

“Once they’re the same age, they age normally until they reach eighteen.”

Damon tilted his head.

“And then?”

Bonnie met his gaze.

“They stop aging entirely.”

Damon stared.

“…Well that’s horrifying.”

Elena looked down at Stephanie again, realization dawning.

“So that’s why she’s growing faster.”

Bonnie nodded.

“It fits perfectly with the legend.”

Elena swallowed hard.

“So how do we know if that’s really what she is?”

Bonnie hesitated.

“There’s a spell.”

Damon immediately perked up.

“Of course there is.”

Bonnie stepped closer.

“It can reveal whether the soulmate link exists.”

Elena looked uncertain.

“What would it do?”

“Just temporarily reveal the mark connected to the bond,” Bonnie explained.

Elena looked down at Stephanie sleeping peacefully in her crib.

“…Okay.”

Bonnie began preparing the spell quietly, drawing a small symbol onto the table before placing her hands over Stephanie.

Soft magic filled the air.

Stephanie stirred slightly but didn’t wake.

A faint glow appeared along her tiny arm.

Slowly—

A small mark formed.

Bonnie leaned closer.

Her eyes widened slightly.

The mark faded within seconds.

Damon stepped forward.

“Well?”

Bonnie looked up at them slowly.

“It’s there.”

Elena felt her heart skip.

“…So it’s real.”

Bonnie nodded.

“Yes.”

Damon crossed his arms.

“Alright. Who’s the lucky soulmate?”

Bonnie hesitated.

“Only I can see the full mark.”

Damon narrowed his eyes.

“Bonnie.”

She sighed.

“It included initials.”

Elena stiffened slightly.

Bonnie looked between them.

“Do you want to know?”

Damon answered instantly.

“Yes.”

But Elena spoke at the same time.

“No.”

Both Bonnie and Damon looked at her.

Elena walked closer to the crib, brushing her fingers through Stephanie’s hair.

“I know what it’s like,” she said quietly.

Bonnie watched her carefully.

“To have people tell you that your fate is already decided.”

Damon softened slightly.

Elena shook her head.

“I won’t put that kind of pressure on her.”

Bonnie nodded slowly.

“Okay.”

Damon sighed dramatically.

“Fine. Mystery soulmate it is.”

After a moment, he glanced back at Bonnie.

“You said only a certain kind of witch could kill her.”

Bonnie nodded.

“Yes.”

Damon frowned.

“What kind?”

Bonnie hesitated before answering.

“…One from the same bloodline as her soulmate.”

The room fell silent.

Stephanie shifted slightly in her sleep.

Unaware that somewhere in the world—

another supernatural being already existed who was tied to her destiny.

 


 

The late afternoon sun filtered through the tall windows of the Salvatore Boarding School for the Young & Gifted, casting long golden streaks across the polished wooden floor of Alaric’s office.

Alaric sat behind his desk, glasses perched low on his nose as he read over a stack of paperwork.

Across from him, Caroline Forbes paced the room with a clipboard in hand.

“No, no, no,” she muttered, flipping through pages. “The dorm assignments for next semester are completely unbalanced. The wolves cannot be on the same floor as—”

The door swung open.

Both of them looked up.

Damon Salvatore leaned casually against the doorframe, hands in his pockets.

Behind him stood Elena Gilbert, holding a bundled baby in her arms.

Caroline’s face lit up immediately.

“Stephanie!”

She rushed across the room in seconds.

“Hi, sweet girl!”

Alaric chuckled, standing up.

“Well, this is a surprise.”

Damon smirked.

“Relax, Ric. We’re not here to donate blood or burn the place down.”

Caroline gently took Stephanie from Elena’s arms, cooing softly.

“Oh my god she’s gotten bigger already.”

Damon and Elena exchanged a brief look.

Caroline noticed the silence.

Her smile faltered slightly.

“…Why do you both look like that?”

Alaric caught it too.

He gestured toward the chairs.

“Okay. Sit.”

Damon and Elena sat.

Caroline bounced Stephanie gently while watching them with concern.

“Alright,” she said slowly. “What’s wrong?”

Elena exhaled.

“There’s something we need to tell you.”

Damon leaned forward, elbows on his knees.

“Turns out,” he said casually, “our daughter isn’t exactly human.”

Caroline blinked.

“…Excuse me?”

Alaric frowned slightly.

“Elena, you’re human now. Damon’s human now.”

Elena nodded.

“That’s what we thought.”

Caroline looked down at Stephanie instinctively.

“Is she sick?”

“No,” Elena said quickly. “She’s healthy. Actually… really healthy.”

Damon rubbed the back of his neck.

“Maybe a little too healthy.”

Alaric crossed his arms.

“Start from the beginning.”

Elena nodded.

So she did.

She explained the feeding issues.

The discovery about blood.

Bonnie’s research.

The legend.

The doppelgänger connection.

The dormant vampirism.

By the time she finished, Caroline’s mouth had slowly fallen open.

“…A natural-born vampire.”

Alaric ran a hand through his hair.

“That’s… new.”

Damon shrugged.

“Trust me, we’re thrilled about it too.”

Caroline looked down at Stephanie again, studying her with fascination.

“So she’s alive… but also technically a vampire?”

Elena nodded.

“And she’ll stop aging at eighteen.”

Caroline blinked again.

“Eighteen?!”

Damon smirked.

“Yeah. Teenage angst forever.”

Caroline gasped softly.

“Oh my god.”

She looked back at Elena.

“She’s going to need so much guidance.”

Elena nodded.

“That’s why we’re here.”

Alaric tilted his head.

“You want her to attend the school.”

It wasn’t a question.

Damon leaned back in his chair.

“Bingo.”

Caroline’s eyes softened immediately.

“You don’t even have to ask.”

Elena smiled faintly.

“I know… but we still wanted to.”

Caroline stepped closer to the desk.

“Of course she’ll have a place here.”

Alaric nodded.

“Absolutely.”

He leaned against the desk.

“The whole point of this school is to give supernatural kids somewhere safe to learn.”

Damon gestured toward Stephanie.

“Well congratulations. You just got the weirdest student you’ll ever have.”

Caroline looked down at the baby again.

Stephanie grabbed a strand of her blonde hair.

Caroline melted instantly.

“Oh my god she’s perfect.”

Damon rolled his eyes.

“She drooled on my shirt this morning.”

Caroline ignored him completely.

“Do Bonnie’s theories entail anything about powers?”

Elena shook her head.

“Not yet.”

Alaric nodded thoughtfully.

“We’ll be ready when they show up.”

Caroline smiled warmly at Elena.

“She’ll grow up here surrounded by people who understand her.”

Elena’s shoulders relaxed for the first time all day.

“That’s exactly what we wanted.”

Damon stood up and walked over, gently poking Stephanie’s tiny hand.

“Plus,” he added smugly, “she’s a Salvatore. This place technically has her name on it.”

Alaric smirked slightly.

“…Fair point.”

Caroline rocked Stephanie gently, smiling down at her.

“Well, Miss Stephanie Salvatore,” she said softly.

“You officially have a reserved spot at the Salvatore Boarding School for the Young & Gifted.”

Stephanie responded by yawning dramatically.

Damon chuckled.

“Perfect reaction.”

Elena laughed quietly.

And for the first time since learning about their daughter’s supernatural nature—

the future didn’t feel quite so uncertain anymore.
