The Abyss Within
Mondstadt had always been a city of song, of laughter, and the gentle murmur of wind-blessed freedom. It was a place of safety, a sanctuary from the chaos that roiled beyond its borders. But in the past few months, something had changed. A shadow had fallen over the city, creeping ever closer with each passing night.
It started slowly—a series of mysterious disappearances in the outskirts, rumors of strange creatures lurking in the woods. And then there were the sightings: a figure, tall and broad-shouldered, moving with inhuman speed and brutality, leaving destruction in his wake. Whispers spread through the city like wildfire, and the people of Mondstadt began to grow wary, unsure of what malevolent force was stalking the darkness.
You had heard these rumors, too, though you dismissed them at first. After all, you had your own distractions to deal with—your meetings with him.
You had met Childe, or Tartaglia as he sometimes called himself, by chance during your travels. He was charming, bright-eyed, and seemingly always one step ahead of you with his playful banter and infectious grin. You had taken a liking to him, finding his adventurous spirit and easy smile disarming. And despite the fact that he was a member of the infamous Fatui, you felt something... different in him.
Childe had become a frequent presence in your life, an unexpected friend, even as you knew there was more to him than the affable, mischievous man who walked beside you through Mondstadt’s markets and taverns. There was something dark beneath the surface, something you couldn’t quite place. But he had never shown it to you—until the night everything changed.
It was a crisp evening when you last saw Childe, sitting by the fountain in Mondstadt’s plaza, his usual confident grin plastered across his face as he waved you over. He greeted you as warmly as ever, but there was a tension to him that you couldn’t ignore. His smile didn’t quite reach his eyes, and his usual lively demeanor felt strained.
“You seem... distracted,” you said, watching him carefully as you sat down beside him.
He chuckled, though the sound was hollow. “Do I? Just a lot on my mind, I guess. The Fatui never rest, you know. But you don’t want to hear about my troubles. Let’s talk about you. How have things been? Still stirring up trouble in Mondstadt?”
His teasing tone was there, but there was an edge to it. He was hiding something. You had known Childe long enough to see when he was masking his true feelings.
“Childe... you can tell me if something’s wrong,” you said softly, reaching out to place a hand on his arm. “You don’t have to pretend with me.”
For a moment, something flickered in his expression—a flash of vulnerability, of conflict. But then it was gone, replaced by that familiar cocky smile.
“Nothing’s wrong. I promise,” he said, standing up abruptly. “Actually, there’s something I wanted to show you. Come with me.”
You hesitated for only a second before following him, the unease in your stomach growing stronger with every step. Childe led you out of the city and into the woods beyond, his pace quick, almost hurried. The sky was darkening overhead, and the air was thick with the scent of rain.
“Where are we going?” you asked, glancing around at the shadows stretching across the path.
Childe didn’t answer right away. His shoulders were tense, his eyes focused ahead. Finally, after what felt like an eternity, he spoke.
“There’s something you need to see,” he said, his voice lower now, more serious than you had ever heard it. “Something I haven’t told you.”
The trees grew denser as you followed him deeper into the forest. Your heart was pounding in your chest, a mix of curiosity and fear swirling in your mind. Childe had always been unpredictable, but this felt different—more dangerous.
Finally, he stopped in a small clearing, the moonlight filtering through the canopy above. He turned to face you, his expression unreadable.
“Do you know why I joined the Fatui?” he asked, his voice barely above a whisper.
You shook your head, frowning. He had never talked about it, and you had never pressed him for answers.
“I wasn’t always like this,” he continued, his eyes dark and distant. “There was a time when I was... different. But something changed me. The Abyss—”
He paused, his jaw tightening as if the mere mention of it was painful.
“I fell into it. I became something else. Something... darker.” His gaze shifted, his usual playfulness replaced with a cold intensity. “I’m not just the Childe you know. There’s another part of me. A part I can’t control.”
Your heart sank as his words began to sink in. You had always known there was more to Childe than he let on, but this was something far worse than you had imagined.
Before you could respond, Childe let out a low, humorless laugh. “I thought I could keep it hidden from you. I didn’t want you to see... him.”
“Who is ‘him’?” you asked, your voice trembling as you stepped closer.
Childe’s eyes met yours, and for a moment, the vulnerability you had seen before returned. But it was fleeting, quickly replaced by something darker.
“You’ll see soon enough,” he said, his voice heavy with resignation.
Without warning, Childe doubled over, clutching his chest as a pained groan escaped his lips. You rushed to his side, panic flooding your veins.
“Childe!” you cried, reaching out to steady him.
But he pushed you away, stumbling back as his body began to change. His once warm, blue eyes turned cold and lifeless, glowing with an eerie orange light. His muscles tensed, his posture shifting into something more animalistic, predatory. His breath came in ragged gasps, his grin twisted into something cruel, dangerous.
“I told you...” he rasped, his voice now a guttural growl. “I’m not always the Childe you know.”
The transformation was complete. The man standing before you was no longer the charming, mischievous warrior you had come to care for. This was someone—something—else. His eyes gleamed with a sadistic hunger, and his movements were sharp, calculated, like a predator stalking its prey.
Fear seized your heart as you took a step back. This wasn’t Childe. This was the monster he had warned you about. And now, you were alone with him in the heart of the forest.
“Childe, please,” you whispered, your voice barely audible over the sound of your pounding heart. “You don’t have to do this.”
But the creature that had once been Childe only laughed, a low, chilling sound that sent shivers down your spine.
“Childe?” he repeated mockingly, stepping closer. “That weakling? He’s always fighting me, holding me back. But not tonight. Tonight, I’m in control.”
Your pulse raced as he circled you, his eyes glinting with malice. This was no longer the man you had trusted, the man you had thought you knew. This was a nightmare brought to life.
You stumbled back, your mind racing as you searched for a way out, but he was too fast. In an instant, he was upon you, pinning you against a tree with a strength that left you breathless.
“Don’t look so scared,” he whispered, his lips brushing against your ear. “You should have known this would happen eventually. Did you really think you could get close to someone like me without seeing the truth?”
His words cut deep, the weight of his dual nature pressing down on you. You had seen glimpses of this side of him before—the ruthlessness, the bloodlust—but you had never imagined it would come to this.
As his grip tightened, you fought to keep your fear at bay. Somewhere beneath the monster that had taken control, the Childe you knew still existed. You had to believe that.
“Childe,” you said, your voice shaking but firm. “I know you’re still in there. You’re stronger than this—stronger than him.”
For a moment, his cruel smile faltered, a flicker of doubt crossing his face. But it was gone as quickly as it had appeared, replaced by a snarl of frustration.
“You’re wasting your breath,” he growled, though there was a hint of something—something fragile and fleeting—in his voice. “He can’t save you now.”
But you refused to give up. “I’m not asking him to save me. I’m asking him to save you.”
His eyes widened, and for a brief, agonizing moment, the monster’s grip loosened. You saw the flicker of recognition in his eyes, the faint glimmer of the man you had come to care for. The two halves of Childe’s soul were at war with each other, fighting for control.
And then, with a shuddering gasp, he let you go, stumbling back as if the weight of the conflict was too much to bear. He collapsed to his knees, clutching his head as he fought against the darkness threatening to consume him.
“Go,” he rasped, his voice raw with pain. “Before I...”
You hesitated, torn between the fear that kept you rooted to the spot and the desperate hope that Childe could still be saved. But in the end, you couldn’t leave him like this. Not when he was fighting so hard to hold on to himself.
You knelt beside him, your hand resting gently on his shoulder. “You’re not alone,” you whispered, hoping your words would reach the man trapped within the monster.
For a long moment, there was only silence, the weight of the night pressing down on you both. And then, slowly, Childe’s breathing began to steady, his tense muscles relaxing as the darkness receded.
When he finally looked up at you, his eyes were blue once more, filled with a haunting mix of relief and sorrow.
“I’m sorry,” he murmured, his voice trembling. “I never wanted you to see that side of me.”
You smiled sadly, brushing a strand of hair from his face. “It’s part of who you are. And I’m not afraid of you.”
Childe looked at you, his expression unreadable for a moment before he leaned in, resting his forehead against yours.
“I’ll always be fighting him,” he whispered. “But as long as you’re here... maybe I can win.”

Albedo
⥽🏮First off would he even tell you?
Yes, this wouldn’t find any reason to not tell you. I mean what is he going to do just hide blood bags from you forever? You’re bound to find out sooner or later so he sees no point in keeping it from you.
⥽🏮How does he get blood?
Although he’s quite aware blood tastes better straight from the source he’d rather drink mediocre blood than harass a random stranger, has artificial blood it doesn’t taste the best but it doesn’t really matter seeing as he drinks to live and not to taste, well I mean that is until he meets you.
⥽🏮 blood preference
Doesn’t mind drinking from blood bags he’s been doing it for most of his life, Bedo honestly doesn’t have that much of a preference but if on the rare occasion he had to choose his favorite blood type would be A positive like I said he doesn’t really mind any blood type but he’d rather not drink B positive, and he really does not understand the whole hype around drinking rare blood types but does share the belief that blood tastes better from the source. He thinks drinking blood from the source is 9/10 immoral and rather disgusted from drinking from an animal
⥽🏮First time feeding off you.
Quite the predicament he got himself into, he was hungry and the next blood supply was until next week. How could he have been so careless? But you were right there outside his office door maybe just one sip, no he can’t he’s better than this of course but then came a loud knock on the door with a familiar voice.
“Bedo! Bedo open the door,please?”
“No, I told you to stay outside of the office didn’t I?”
“Yes but- you know what I’m coming in.”
“[name] do no-”
Words cut off by the slamming off the door he specifically told you not to open, your eyes glance over him with a slightly annoyed face and blonde wisps over his bare face and braid messily done. Admiring his appearance and sliding next to him.
“Is it my words weren’t clear enough for you to hear me?”
“No, I heard I just didn’t want to sit outside the door while my boyfriend is sitting alone in pain.”
“It’s not that bad.”
“It is, now here.”
You shift your shirt slightly off your shoulders revealing your collar bone, he knew what you were trying to insulate you couldn’t make it more obvious, he didn’t want to do it but you were right in front of him and oh so close.
“[name] I’m not going to.”
“Bedo, please.”
“No.im no-”
“For archons sakes!”
Startled by the sudden hands grasping his hair on forcing his fangs to skin into your soft skin, he wanted so much to stop drawing blood from you but mouthwatering liquid dripping from your collarbone that was trickling into his mouth was delightful, it didn’t hurt fact you kind of liked the sensation but as soon as you started to get familiar with the tingling feeling traveling threw your body making your eyes to flutter it stopped, why?
“I- I’m sorry, I lost control and-”
“It’s fine bedo it didn’t hurt, in fact, I kinda liked it.”
“Oh, so that’s the case?”
Eyes staring right at your figure with an ever so menacing look, you don’t know what you were in for, but it was something, surely something.
Childe
⥽🏮would he even tell you?
He would try and keep it from early on in the relationship, but would eventually tell once he knows for sure he can trust you with that information, don’t get me wrong it’s not that he doesn’t trust you it’s about how much you trust him.
⥽🏮How does he get blood?
Kidnapping, look ok I know it sounds bad but this man just absolutely despises blood bags. he‘s so picky with his blood too like if you are not dressed a certain way or your blood doesn’t flow through your veins like he wants he would not even consider drinking from you if he was starving to death.
⥽🏮 blood preference
You would think he would be stuck up about it and only drink AB negative, but no he’s just picky there’s a difference! His favorite blood type is b negative but he absolutely can not stand RH negative and like albedo does not understand the hype around ab negative. Speaking about what he likes drinking from, he shares the popular belief that blood tastes better from the source, disgusted by blood bags and even more disgusted about drinking from an animal
⥽🏮First time feeding off you.
Your husband was no stranger to having to get up at 3 in the morning to do something he really would rather not do you knew this, but this specific pattern of getting out of bed only when in sept like you were asleep was extremely irregular even for childe. I mean who just gets up in the middle of the night then comes back 2 hours later. Well, you were about to find out, it's not as if you didn't trust your husband or something it's that you wanted him to trust you with whatever he’s hiding from you.
So you were going to do the obvious thing and catch him in the act, and well the man was caught red-handed, to say the least, no like literally there’s blood on his hands and his mouth what the fuck.
“Ajax is that…?”
“Look I know it looks bad but I was on a mission a- and”
“So mission huh? That definitely explains the blood in your mouth and you go out at the exact same time and only when im asleep right?”
“I know, but I swear it wasn’t anything that bad, trust me, love.”
“Don’t love me, look ajax if you’re not going to trust me why should I trust you?”
“Ah, well your right I guess it’s time to tell you.”
“Waiting?”
“Im, a vampire.”
“That’s all?”
“I mean yeah, what else would there be?”
“Oh thank archons, I thought you were cheating on me.”
“Love what? I would never do that not even I was held at gunpoint!”
“Well, im glad to know it was nothing serious.”
What a nice moment between you too, carrying you up the stair and to your bedroom draping your figure onto the silk sheets. Childe positioned over your body starting at his features with anticipation.
“Can I?”
You nod your head in agreement with the statement he just made. His teeth submerging into your skin as if he’d tasted nothing better in his whole life, blood trickling down your throat. A sweet mixture of pleasure and pain, it was a long night, yeah let’s leave it at that.
Kazuha
⥽🏮would he even tell you?
Yep, 100x yep this man can’t stand keeping secrets from you and he also doesn’t see the point in not telling you if he’s going to spend the rest of his life with you, you need to know every secret about him.
⥽🏮How does he get blood?
Beido buys blood from him, he was a bit suspicious about the morals of how this blood was acquired but she assures him that everything was consensual. He thinks it tastes fine and would rather drink it than accidentally harm someone He’s picky but the type he likes isn’t rare so it’s not much of a problem.
⥽🏮 blood preference
Picky but not anywhere near to as childe, if you give him something he doesn’t like he’ll normally just wait for beido to buy sum’ more but if he needs it he’ll drink it. His favorite blood type is o positive which is great for him since its the most common one-time beido offered to for him to drink her blood and that is how he found out he really dislikes A negative quite immoral to just drink from random humans especially when it’s not consensual and he just can’t stand the taste of animal blood.
⥽🏮First time feeding off you.
Knowing that Kazuha was a vampire wasn’t a big deal for you, stirring the pot of food wondering about what even has changed, oh right the most that changed is probably just your cooking habits but besides from that everything was the same. There was something that didn't bother per say but you always wondered about-
“Zuha’ love, can you come in the kitchen for a sec?”
“Mhm sure.”
As soon as you spoke you could hear the familiar footsteps of the man you love, you were about to ask him a question that had been on your mind for the last month.
“so, is there something you need dove?”
“no, not necessarily I just wanted to ask you a question, is that all right?”
“Ask away.”
“So u- Uhm why do you never drink from me is it like my blood tastes weird or?”
“Oh, well I wasn't expecting that. I thought you never wanted to since you never asked, would you like me to?”
“Mhm!”
If Kazuha knew you would have that look on your face when he was about to drink from you he’d of done it much sooner, and there his canines digging into the side of your shoulder as the red liquid hit his tongue, he’s never tasted anything better, screw any other blood type yours is the best by far. Oh, how he just never wanted to stop the tension of your skin and his teeth but there was an issue why are your eyes fluttering like that?
“Sorry, I didn't realize I was taking that much forgive me, are you ok?”
“Im fine love! Just a bit light-headed, you should do that more often.”
“I would love to dear, by the way, what are you making it smells good.”
