Summary:

Horde Prime is going to get what he deserves

Notes:

Alright-- tags, yeah there's some troubling ones, there's some confusing ones. I maintain some spoilers by not adding some yet but I feel like this has covered most things that could be upsetting to have sprung on readers. I did put the warnings in because of flashbacks throughout and chapter 2 specifically.

Chapters will alternate pov based on what the story needs.

If you're reading this you would probably know that this is based on Captive Prince, book 3 (King's Rising). There's a lot of missing context it you start here, please start at Disposition.

The chapter count can only go up, not down, trust me. Is this earlier than I intended? Yup.

Enjoy 🙂

Chapter 1: Adora

Chapter Text

“She-Ra.”

“Adora.”

Her name hit the quiet like a dropped weapon. The sound of it rolled across the courtyard, carried by disbelief.

Adora stood at the foot of the dais. Mermista knelt before her, one knee down, head bowed. Behind her, rows of Salinean soldiers followed suit—shields angled, tridents lowered, the motion spreading like wind through grass. So smooth it was mesmerising. 

For half a second, Adora felt the quiet of homecoming. Then the silence broke.

The word passed from soldier to soldier, carried outward to the Horde citizens crowding the walls. The tone changed—first confused, then sharp, then furious.

“Mage-slayer!” someone shouted.

It came again, louder, multiplied. The air tightened.

Something whistled past Adora’s shoulder and clattered against the stone. A rock. Then another.

Mermista was already up. Her hand snapped, and water gathered around her in spiraling arcs, rising from the puddles that had pooled under the morning fog. The surface shimmered and hardened to blade points.

“Stand down,” Adora said, throwing out her arm.

Mermista stopped—but her jaw worked, and her eyes burned. “They’re throwing things at you,” she said flatly.

“I said stand down.”

The water froze mid-air. Droplets hovered, vibrating.

Adora turned her head. A Horde soldier had drawn his sword—one in grey, shaking so hard the blade rattled against the hilt. Clone 13. She knew him.

“Captain Mara?” His voice cracked on the name.

Adora didn’t blink. “Hold!” she barked, louder this time, her tone all command.

The crowd didn’t listen. Panic started to eat at the edges. Shouting. The sound of boots scraping, of shields striking together. Horde guards pushed toward the front, shouting orders that no one heard.

Mermista’s troops held formation, but barely. The line flexed, tension snapping through every pair of shoulders.

Another sword came free. Then another. The sound of metal being drawn was everywhere.

The Horde soldiers were terrified—some angry, some frozen. Adora could see it all from where she stood: the fear, the split-second weighing of fight or flight. Clone 16’s eyes flicked between her and the gate. He saw what the commoners in the crowd didn’t: Etherian soldiers already inside, already surrounding them, fifteen to one.

Adora’s pulse steadied. She could feel the decision form in her chest, as cold and certain as ice.

This wasn’t going to be saved by words.

She’d misjudged it—the hope that her name could mean unity, that it could bridge the years of war. To the Horde, it still meant death.

She-Ra. Adora. Mage-slayer.

The chant of the latter moniker was starting again. Louder now.

Adora lifted her chin and looked at Mermista. “We end this before it spreads,” she said quietly.

Mermista’s expression hardened. “You sure?”

Adora’s voice didn’t rise. “Take the fort.”

Mermista gave a short nod. “Fine. But you’re explaining this later.”

The water around her surged forward, rippling into shape as she turned away.

Adora’s boots hit stone hard enough to echo down the hallway. Six guards moved with her, fishscale armor clinking in time. Etherian banners hung over the corridors—white cloth, gold trim. 

Talon Mountain had changed hands twice in seven days. The first time had taken a whole day of fighting. The second—hers—had taken less than one hour. Adora didn’t feel proud of that. She just knew exactly where to strike.

The Horde garrison had broken before sundown. Now its commanders waited for her. Clone 16. And Lonnie.

The antechamber was bare. One lamp. Stone walls. A single table pushed to the side. Two Etherian guards shoved the prisoners forward and barked, “Kneel,” in thick, broken Horde speech.

Lonnie didn’t. She caught herself with one hand, half a stumble, half a refusal.

“No,” Adora said. “Let them stand.”

Her tone was quiet, but the guards dropped back at once.

Clone 16 was up first, shoulders stiff. Lonnie followed slowly. Her wrists were bound but her spine was straight.

Clone 16 spoke first, “So it’s true. You’re Adora of Bright Moon.”

“It’s true,” she said.

He spat on the floor. A guard hit him instantly—the smack of metal gauntlet against skin. His head snapped sideways.

Adora didn’t stop it.

He wiped his mouth, blood on his thumb. “You going to kill us?”

Adora looked him over, then Lonnie. Dust. Bruises. Hollow eyes. Lonnie’s jaw was set in a way she recognized—the same way she had looked when she found out a week prior. The same way she had looked after Catra had verbally torn Entrapta apart. The same way she looked when she had spent an hour saying goodbye to Entrapta.

“I’m giving you a choice,” Adora said.

Lonnie gave a short laugh. “Yeah, I’ve heard that one before. Serve me or die. I was on Prime’s flagship for years, remember?”

Adora ignored her. “Etheria isn’t here to occupy your fort. We’re here to fight Prime. You know what he is. You’ve seen what happens to those who stand alone.”

Clone 16 let out a shaky breath. “And if we ‘choose’ wrong?”

“Then you stay here,” Adora said. “Prisoners. Or you come with me to Seaspray and help end this before it reaches Bright Moon.”

He glared at her. “You don’t get it. We don’t fight beside you. You—” He stopped himself, jaw locking. “You betrayed her. You had her—”

“Get him out,” Adora said flatly.

The guards grabbed Clone 16 and hauled him toward the door. Adora gestured for the rest to leave. Only one remained.

Lonnie stayed where she was, breathing hard but steady. When the door shut, the silence thickened.

“You don’t have to play commander with me,” she said finally. “You think I don’t know what this is?”

Adora didn’t rise to it. “I made her a promise.”

Lonnie’s head tilted. “And when she finds out it’s you? That She-Ra’s the one she’s fighting beside?”

“Then that’s when we meet,” Adora said. Her voice was low now. “For real.”

Lonnie looked at her for a long time. Then she gave a small exhale that might’ve been a laugh. “Yeah. That’s gonna go great.”

When it was done, Adora stopped in the doorway, her hand on the frame to steady herself. She thought of her name, already spreading through the fort, through the mountains, down into the towns. A sound traveling ahead of her like a wave she couldn’t take back.

If she could hold this place, hold her people together long enough to reach Seaspray… maybe that would be enough. Maybe that would make the rest of it bearable.

She pushed the door open and stepped into the hall.

Mermista was there, standing near the table, water still dripping faintly from her armor. She turned at the sound, eyes flicking over Adora, taking in the state of her.

Before Adora could say anything, Mermista dropped to one knee—not fast, not dramatic, just a show of respect.

“The fort’s yours,” Mermista said. “My Queen.”

The word hit Adora like a slap.

Queen.

It was her mother’s title. The sound of it crawled over her skin. For a heartbeat, she thought she could smell the lilies her mother used to grow, hear the echo of her voice in the Bright Moon halls. But that throne was Glimmer’s now. Bright Moon had moved on.

Looking at Mermista—her friend—kneeling there in a captured Horde stronghold, Adora felt it for the first time: there was no Princess Adora anymore. That self was gone.

You get everything you ever wanted, and it still costs you everything else.

Hadn’t Catra said something similar?

Adora blinked the thought away and looked down at Mermista: her damp teal hair sticking to her neck, her armor scuffed, the faint salt smell of salt still clinging to her. Once, they’d raced barefoot through the halls of Salineas, laughing, sand still on their legs from training. Back then, Adora had imagined coming home would feel like that—like sunlight, like laughter.

Instead, her friend was kneeling in a Horde fort.

“Rise,” Adora said quietly. “Please. Mermista.”

Mermista stood, brushing dust from her knee, eyes searching Adora’s face. “You look… alive,” she said after a beat. “Didn’t expect that.”

Adora managed a breath that might’ve been a laugh.

“I thought you were dead,” Mermista went on. “I sent out scallop candles. Swam out to the mourning stones. You were supposed to be gone.” Her tone wasn’t accusing—just flat, stunned. “What the hell happened?”

Adora looked at the table, at the small flicker of lamplight across it. “Bright Moon was infiltrated,” she said. “A shape-shifter. They killed Angella, faked my death, sent me to The Horde as a prisoner.”

She stopped there. It was enough for now.

Mermista was still watching her. “I saw Glimmer crowned,” she said finally. “She stood under her mother’s Runestone. Said something about loss teaching us to hope again.” Her brow furrowed. “It sounded… kinda rehearsed.”

Adora didn’t answer. She could picture it easily—Glimmer on the dais, Bow behind her, the air thick with incense to cover the stench of death in the castle. The world carrying on without her.

“Tell me,” Adora said.

So Mermista told her.

She told her how Bright Moon had held a procession for her body, wrapped in silk and carried beside Angella’s. How Glimmer had spoken, tears perfect and visible, the whole court watching. How the story changed depending on who asked: Adora killed by her own guard, her guard executed for treason, chaos swallowing the palace.

Mermista’s tone stayed even. “Bow’s soldiers locked everything down after. Said they were keeping order. Said no one else needed to die.”

“Did you believe them?” Adora asked.

Mermista’s mouth twitched. “I wanted to. It was easier.”

Adora nodded slowly. “Do you think she knew?”

“I don't know,” Mermista said. “Maybe Glimmer just didn’t want anyone knowing how bad it really was. How easy it was to take out two Queens so quickly.”

Mermista looked down. “Welcome home, I guess.”

Adora didn’t look up. “If it still is.”

“There’s more,” Mermista said.

The words came out like something she hadn’t wanted to say. She hesitated, studying Adora’s face as if deciding whether it could handle what came next. Then she reached into the side of her fishscale breastplate and pulled out a folded piece of paper, stiff with salt and age.

She held it out. “Here.”

Adora took it carefully. The letter had been wet at some point; the edges curled, ink blurred. She unfolded it slowly, the smell of sea air clinging to the parchment.

To the Princess of Salineas, Mermista,

from Catra, Princess of the Horde.

The name alone made Adora’s breath hitch. She ran her thumb over the fading ink. The strokes were familiar—deliberate, sharp at the corners. Catra’s hand.

It was old. She could tell by the wear of the paper, by the brittle fold lines. Adora could almost see her—sitting alone, lamplight on her desk, the edge of her mouth drawn tight the way it always was when she was pretending not to care. Do you think I’d get on with Mermista of Salineas? she’d asked once, smirking like it was a joke.

The thought twisted in her chest. It made sense, of course. Catra was always good at doing what she had to, no matter how much it hurt someone. She could turn loyalty into a tool and friendship into leverage. It wasn’t cruelty. It was survival.

Adora skimmed the contents. An offer—aid from Salineas in exchange for proof that Double Trouble had worked with Prime to assassinate Queen Angella. The same truth Catra had thrown in her face nights ago.

Mermista folded her arms. “We didn’t know what to believe,” she said. “Glimmer always had an answer. Every time someone questioned her, she had some new version ready. She was Angella’s true daughter. You were dead. That was enough for most people.”

Her tone sharpened. “Castaspella swore loyalty first. After that, everyone else followed.”

Adora looked up. “You don’t think Glimmer’s giving up the crown easily.”

Mermista gave a small snort. “Please. Have you met her? She's stubborn."

That pulled the faintest smile from Adora, one that didn’t reach her eyes.

She knew what waited ahead—Glimmer’s certainty, her defenses. She hadn’t dared hope to hear anything else. But hearing Mermista say it aloud turned hope into something painful.

“The west still remembers you,” Mermista said after a moment. “The soldiers. The coastal towns. They haven’t forgotten what you stand for.”

“And if I ask them to fight?”

Mermista didn’t blink. “Then we fight. Together.”

The words hit her harder than she expected. Not the promise, just the ease of it. No hesitation, no suspicion. Just trust. The kind she hadn’t felt in too long.

Mermista turned away, went to the chest near the wall, and opened it. Metal creaked. She lifted out a long bundle wrapped in cloth.

“This is yours,” she said. “I shouldn’t have kept it. Treason, technically.” Her mouth tilted, almost a smile. “Guess I’m still bad at politics.”

She unwrapped the cloth. Light caught on polished gold metal.

The Sword of Protection.

Mermista held it out with both hands. “I kept it to remember you. Stupid, maybe. But I couldn’t let them take it.”

Adora reached for it slowly, as though the air between them might break. The metal was cool against her palms, heavier than memory had made it.

“You shouldn’t have risked this,” she said quietly. “Not for me.”

Mermista shrugged, faint amusement ghosting over her face. “Maybe I just wanted to be the next She-Ra?”

Adora quirked an eyebrow at her and Mermista shrugged. “It didn't work.”

Adora looked at her. “You’re too quick to pledge yourself.”

“You’re my Queen,” Mermista said simply.

Queen.

The word didn’t feel like victory. It felt like loss that hadn’t finished echoing through her. She had no time to process her grief.

She gripped Mermista’s shoulder, the touch brief but steady. It was all she had to offer right now.

Mermista glanced down at Adora’s uniform—the dark red, the sharp seams, the clean military lines. “You know,” she said, tugging lightly at the sleeve, “you really do look like a Horde officer.”

Adora almost rolled her eyes. “Yeah, well—”

Mermista froze. Her hand stayed at Adora’s wrist, eyes narrowing.

“Adora,” she said quietly.

Adora followed her gaze. The sleeve had slipped.

A wide band of platinum encircled her wrist—cold, smooth and unbroken. At her own request.

Mermista stepped back as if struck. Her eyes went wide, her mouth opening, closing, words failing before they formed.

Adora caught her arm. “Mermista. Don’t.”

Mermista froze, torn between instinct and the part of her that had always followed orders, however apatheticly. Adora could feel the tension in her muscles, the effort it took her not to pull away.

“Please,” Adora said quietly. “Listen.”

Her voice felt foreign in her mouth, like she was hearing herself from a distance. Her pulse was hammering. “Yes,” she said, forcing the word out. “It’s true.”

Mermista blinked. “What?”

Adora swallowed. “Double Trouble sold me to the Horde. Catra freed me. She gave me command of her troops. She doesn’t even know who I really am.”

The color drained from Mermista’s face. “She freed you?” The word caught in her throat. “Freed you from what, Adora?”

Adora didn’t answer, but the look was enough.

“You were her—” Mermista started, and then stopped. Her voice thinned. “You were her bed slave?

The title hung in the air, small but shattering.

A sound came from behind them—soft and shocked.

Adora turned.

Frosta stood in the doorway, hand still half-raised as if she’d meant to knock and forgot how. Behind her, two Salinean guards stood stiff, eyes down.

For a long moment, no one moved.

Adora felt the heat crawl up her neck. She dropped Mermista’s arm. The room was too quiet.

The platinum cuff caught the light when she moved. That was all it took. The meaning was clear. Everyone in the room knew what a cuff like that meant.

She could feel their eyes on it, on her—and worse, on the picture they were already building in their heads. The kind of picture that couldn’t be undone.

She forced her hands still. “Yes,” she said. “You’re seeing it right.”

Her voice sounded dry. She rolled her sleeve back further until the full band of metal was visible. She said. “I was the Horde Princess’s Slave. And she—” her voice hitched, just once, “—she gave us this fort.”

Mermista’s jaw set. “Stop.” She turned sharply toward Frosta, her voice hard. “You don’t repeat this. You don’t even breathe this to anyone outside this room.”

Adora shook her head. “No. It’s done. People already know.”

Frosta’s eyes were fixed on the cuff. Her voice came out low, clipped. “You served the Princess of the Horde as a bed slave?

Adora met her gaze. “I survived. That’s all that matters.”

Frosta’s mouth thinned. “You’re our Queen. This—” she gestured vaguely, her hand trembling just once— “this is shameful to Etheria.”

Adora didn’t flinch. “You’ll bear it,” she said. “As I did. Or are you above your Queen now?”

Frosta’s stare was sharp, but her silence gave her away. Not a queen, a slave.

Adora saw the fight in her eyes—pride, disgust, the same kind of pride that had made her mother’s court unbreakable and cruel. The idea of her Queen marked, owned, made her shoulders tighten.

Mermista broke the silence. “If word spreads,” she said slowly, “I can’t promise the troops won’t turn.”

Adora’s reply was quiet, certain. “It’s already spread. Everyone already occupying the Fort knew I was her slave. Do you think they won't talk?”

Mermista’s throat worked once before she answered. “Then what do you need from us?”

Adora looked between them. Her face had gone still, her voice stripped of anything soft. “You make your pledge,” she said. “And if you’re mine, you gather the soldiers. We fight.”

No one spoke. Frosta bowed her head, just enough to count. Mermista didn’t move.

The plan she’d made with Catra wasn’t overly clever. It depended on timing and nerve.

Seaspray wasn’t like the Talons. It wasn’t open ground—no straight lines, no clear sight. It was a bowl of ridges and hollows, thick with brush and fog that clung to the sand. Easy to lose formation there. Easier to die in one.

Prime had picked it on purpose. He liked traps. He liked control. Inviting Catra to fight there was the same as daring her to walk straight into his teeth.

So they’d turned the trap over. Catra had taken her riders north-west two days ago. She’d swing back around and hit Prime’s rear once his forces were pulled toward the coast. Adora’s army was the lure.

Before stepping out, Adora sat still for a moment, staring at her wrist. The metal cuff glinted. She left it visible.

Her Horde uniform was gone. She wore She-Ra's form instead—white, gold, and too bright under the daylight. Bare arms. Bare legs from the knee to mid thigh. The cape pinned with gold disks at her shoulders. It felt lighter than it should have. It felt right to take on her form again. 

When she walked out onto the dais, the noise in the courtyard died. Thousands of soldiers stood in ranks below—Salinean teal, Bright Moon white, Northern navy. Armor catching light, lines straight and disciplined.

She let them look. Let them see her—the cuff, the sword, the body that rumour said had risen from the dead.

When she spoke, her voice carried clean, unforced.

“Soldiers of Etheria,” she said. “I am Adora. True daughter of Eternia. I’ve come back to fight for you—and with you—as your Queen.”

For a heartbeat, there was silence. Then the courtyard erupted. Tridents and spear-butts struck the ground. Voices broke the stillness like thunder rolling down the slopes.

She found Frosta among the first line—face unreadable, hand tight around her weapon.

Adora gave a nod. It was enough that she was here.

The horns sounded. Standards rose. The skiff she’d used at the Talons slid forward on its hover field. She stepped aboard, and the soldiers opened a path through the ranks.

Then came another sound—sharper, off-beat. Metal scraping stone.

A handful soldiers in red and black on skiffs pushed through the crowd. 

The Etherian ranks bristled—shields came up, a ripple of tension moving down the line.

Adora raised her hand, palm out. “Stand down.”

The red-and-black skiffs slowed. Lonnie, with Clone 16 and Clone 28 flanking her.

The skiffs circled once before Lonnie eased hers close enough to be heard. “We’re not here to fight you,” she said. “We’re here to fight with you.”

Adora studied the group—the mix of Horde insignia and Etherian eyes on them from every side. Lonnie met her gaze, steady.

Adora gave a short nod. “Then we fight,” she said. Her voice wasn’t loud, but it carried. “For Etheria. For the Fright Zone.”

Adora raised her sword, the light catching across the metal. The sky above the sea had already started to darken—the kind of gray that promised rain.

The fog thickened the closer they got to Seaspray. The air was wet and heavy with salt; the ground under the skiffs had turned from firm dirt to sliding grit. The ridges were uneven, folding in and out of sight like broken waves. Scouts vanished into the haze, their reports coming back in quick bursts: Prime’s army pushing from the west and—higher ground, better cover.

Adora’s troops were in the bowl, down in the fog. Bait.

She’d never have led soldiers into ground like this without a plan to claw out of it. The numbers were bad, the terrain worse. If Catra didn’t hit from the north when expected, they wouldn’t make it through the day.

Mermista stared out at the hills. “This is a choke point,” she said flatly. “You know that, right?”

Adora didn’t look at her. “We need him overcommitted. It has to happen here.”

“Yeah, sure. Great place for dying tragically.”

Frosta’s Elk came up alongside, her voice cutting through the fog. “Visibility’s dropping fast. We can’t see the treeline.”

“Scouts will hold the perimeter,” Adora said. “Stay ready. Don’t move until I call it.”

She kept the plan in her head like a map: Prime advances from the west; Etheria holds the valley floor. Once Prime’s troops are fully inside, Catra’s division crashes down from the north-west, splits the line, traps them between. 

Trust me, Catra had said. 

Adora raised her hand. “Form up,” she ordered.

The clatter of armor and the scrape of skiff runners and mounts shifted through the fog. Soldiers took their places, shields up, lines tight. The air went still. That particular kind of silence that meant everyone could feel the weight of what was about to happen.

“They’ll open from the west,” Adora said. “Wait for my mark.”

A distant horn sounded through the valley, long and hollow.

“Hold,” Adora said.

Movement flickered in the fog—the outline of enemy banners, glints of light off metal.

“Hold.”

Another horn, this one closer.

Then a ripple of motion to her right—the western flank shifting forward. She turned sharply.

Frosta was advancing her riders. The ice running from her hands hissed as it hit the damp ground.

“Pull them back,” Adora snapped, cutting across the open space to intercept.

Frosta didn’t even flinch. “We’re taking position on the ridge. You’re wasting time.”

“My order was to hold,” Adora said, circling her skiff closer. “Prime’s waiting for this exact mistake. Let him come to us.”

“If we wait, and your Princess doesn’t show, we’re slaughtered.”

“She’ll come,” Adora said, sharper now.

Frosta’s reply was a short, cold laugh. “I know you believe that.”

Before Adora could answer, another horn split the air, this one from the north.

Too close.

Her head snapped up. “That’s not possible—”

But the sound of engines cut her off. A low, fast hum that built until it filled the valley. From the treeline ahead, shadows burst through the fog—Prime’s clones, pouring downhill.

A single Etherian scout broke from the tree line, riding flat out. His voice carried over the noise. “She’s not coming! Catra’s not—”

The crack of a blaster. He dropped mid-sentence.

Frosta turned toward Adora. “There’s your Horde Princess for you,” she said.

Adora didn’t answer. The first volley hit before she could.

Metal screamed. Soldiers shouted, some dropping where they stood. Bullets tore through the fog in whistling arcs. Adora’s voice cut over it — “Shields up! Fire on my mark!”—but the lines were already breaking, forced back under the weight of the charge.

She felt the shock of it, the noise, the bodies slamming against hers in the confusion.

Prime’s plan was clear now—turn her army into the wall Catra could never breach.

Another horn, this one from the northwest. A second wave. The surround was complete.

Adora forced her skiff through the crush, cutting toward the front line. Her shoulder hit something solid—a red and black blur that turned out to be Lonnie, steering hard to stay upright.

“Go east,” Adora shouted. “Now. You can still get clear.”

Lonnie glanced at her, hair plastered to her face, eyes sharp and furious. “She’s not coming, is she?”

Adora didn’t look back. “We’re outnumbered,” she said. “If you run, some of you make it out.”

“Yeah? And what about you?”

Adora gripped the controls tighter. The line ahead was collapsing. “I’ll do what I always do.”

Lonnie’s voice came over the roar. “And what’s that?”

“Fight.”

She slammed the throttle forward and vanished into the smoke.
