Sister Mercy stood in the hallway outside the medicae ward, her hands clasped tightly together, her expression troubled.

  Sister Prudence stood beside her, arms crossed, her weathered face carved with lines of worry that seemed deeper than usual.

  They hadn't spoken in several minutes. Just stood together in tense silence, the weight of Eve's confession still hanging heavy between them.

  Finally, Sister Mercy broke the quiet.

  "I don't know what to do," she admitted softly. "A child created as a weapon. Another who opened a door to the Warp and killed dozens. Gene-seed experiments. And now this fever that won't break. Sister Prudence, I'm... I'm lost."

  Sister Prudence's jaw tightened, but her voice was steady. "We keep them stable. We keep them hidden. And we pray the Emperor shows mercy."

  "And if He doesn't?"

  Sister Prudence had no answer for that.

  The sound of small footsteps interrupted their conversation.

  Both women turned to see Lysander approaching, his expression worried, his hands fidgeting with the hem of his robe.

  "Sisters?" he said hesitantly. "Are... are Lilith and Eve okay?"

  Sister Mercy's stern expression immediately softened. She knelt down to his eye level, her voice gentle despite the fear churning in her chest.

  "They're fine, sweetheart. Just resting. They need time to recover, that's all."

  Lysander nodded, but the worry didn't leave his face. "Can I see them?"

  "Not right now. Eve is with Lilith, and they need quiet. But I promise, when they're feeling better, you'll be the first to know."

  "Okay." Lysander turned to leave, then paused, glancing back. "Sister Mercy?"

  "Yes, child?"

  "If... if they need help. Like, real help. The Salamanders could help them. I know they could."

  Sister Mercy blinked, surprised. "The Salamanders?"

  Lysander's face brightened with the enthusiasm only a child could muster. "Yeah! They're the best! They help people all the time, even normal people like us. If Lilith and Eve are sick or hurt or something, a Salamander could fix them! They're really strong and really smart and they know about everything!"

  His innocent faith was almost painful to witness.

  Sister Mercy managed a smile. "That's very sweet of you to think of them, Lysander. I'm sure the Salamanders are wonderful. Now run along—it's almost time for evening prayers."

  "Okay!" He scampered off, his footsteps echoing down the hallway.

  Sister Mercy stood slowly, her mind turning over his words.

  The Salamanders.

  She turned to Sister Prudence. "Lilith asked me about them. The Salamanders. Just a few days ago. She wanted to know more about them because of her eyes—the red glow. She thought there might be a connection."

  Sister Prudence nodded slowly. "I remember you mentioning that."

  "What if..." Sister Mercy hesitated. "What if we could get their help? The Salamanders are known for their compassion, their willingness to protect civilians. If we explained the situation—"

  "No."

  The word was flat, absolute.

  Sister Mercy stared at her. "But—"

  "We should not disturb the Adeptus Astartes for the sake of one child," Sister Prudence said firmly. "They have duties. Battles to fight. Worlds to defend. They cannot be expected to drop everything to tend to a sick girl in an orphanage."

  "She's not just sick. She's—"

  "I know what she is." Sister Prudence's expression was hard. "And that's precisely why we shouldn't involve them. If the Salamanders investigate, they'll uncover the truth. Gene-seed experiments. Warp exposure. Potential corruption. Do you know what happens when Space Marines discover something like that?"

  Sister Mercy's throat tightened. "They'd execute her."

  "Exactly. The Inquisitor might show restraint. The Ecclesiarch might show mercy. But Space Marines? They are the Emperor's finest warriors. They do not take chances with potential corruption. They would see a failed psyker experiment with Warp taint and they would act."

  Sister Mercy looked away, her heart sinking.

  "However," Sister Prudence continued, her tone softening slightly, "if there were a way to contact them discreetly. To present the situation in a manner that emphasized compassion rather than threat... I would not stop you from trying."

  Sister Mercy looked up sharply. "You'd allow it?"

  "I didn't say that." Sister Prudence's expression was carefully neutral. "I said I wouldn't stop you. There's a difference. What you do on your own time, without the knowledge or approval of this institution, is your own responsibility."

  She met Sister Mercy's eyes.

  "But there is no way to contact them. We have no channels. No connections. They do not simply answer requests from nuns in hive orphanages."

  Sister Mercy nodded slowly, understanding the unspoken message.

  If you want to try, I won't report you. But you're on your own. And if you fail, you face the consequences alone.

  "Understood, Sister."

  Sister Prudence turned and walked away, her footsteps measured and precise.

  Sister Mercy stood in the hallway for a long moment, staring at the closed door of the medicae ward.

  Inside, a child lay dying from forces beyond mortal comprehension.

  Outside, the gears of the Imperium ground forward, indifferent to individual suffering.

  And somewhere between those two truths, Sister Mercy made a decision.

  That night, long after lights out, Sister Mercy knelt in her small cell.

  A single candle flickered on a makeshift altar—a crude carving of the Aquila, a tattered prayer book, a rosary made of simple wooden beads.

  She prayed.

  Not the rote recitations she led the children through every day. Not the formal liturgies of the Ministorum.

  This was raw. Personal. Desperate.

  "God-Emperor," she whispered, her voice cracking. "I know I am unworthy. I know my faith is imperfect. But I beg You—show me a path. Give me strength. Help me save that child."

  Silence answered her.

  But Sister Mercy had been praying long enough to know that silence didn't mean absence.

  She crossed herself, stood, and began to prepare.

  From beneath her cot, she pulled out a small pack. Inside: a rebreather mask (essential for prolonged exposure to the hive's toxic air), a compact lumen torch, a knife (for protection, not battle), a data-slate with addresses and contacts accumulated over years of service, and what little currency she'd managed to save.

  She dressed in civilian clothes—plain, nondescript, the kind worn by millions of hive workers. The Ministorum robes stayed behind, folded carefully on her bed.

  If I'm caught, I can't implicate the orphanage. This has to look like a personal failing, not institutional involvement.

  She checked the rebreather one last time, secured the pack, and slipped out of her cell.

  The orphanage was silent. Dark. The children slept, the other sisters in their quarters, the night watch minimal.

  Sister Mercy moved through the shadows with practiced ease, her years of navigating the building serving her well.

  She reached a side entrance—a maintenance door rarely used, its lock old and temperamental. She'd oiled it yesterday in preparation.

  It opened without a sound.

  And Sister Mercy stepped out into the hive.

  Armageddon's night air hit her like a physical force.

  Even through the rebreather, she could taste the toxins—metallic, acrid, clinging to the back of her throat. The sky above was obscured by layers of smog and industrial haze, the only light coming from distant forge fires and the perpetual glow of manufactorums.

  The streets were crowded despite the hour. Hive cities never truly slept. Shift workers trudged to their posts. Gangers prowled the shadows. Merchants hawked goods from makeshift stalls. The desperate and the damned moved through the cramped corridors of humanity like blood through diseased veins.

  Sister Mercy pulled her hood up and joined the flow.

  Her first stop was three levels down—a small recaf shop run by an old woman named Hessa.

  Sister Mercy had helped Hessa's grandson years ago, getting him into the orphanage after his parents were killed in a gang war. The boy was grown now, enlisted in the Steel Legion, but Hessa remembered.

  The shop was cramped and dirty, but warm. Hessa looked up from behind a stained counter, her rheumy eyes widening in recognition.

  "Sister?"

  "Not tonight, Hessa. Tonight I'm just Miriam."

  Hessa's expression shifted to concern. "What's wrong?"

  "I need information. About the Salamanders. Are any stationed in this hive right now?"

  Hessa's eyebrows rose. "The Space Marines? Why would you—"

  "Please, Hessa. It's important. Life or death."

  The old woman studied her for a long moment, then nodded slowly. "There's rumors. Upper hive. Diplomatic meeting with the planetary governor. One of their Chaplains, I heard. But Sister—Miriam—those are just rumors. I don't know if—"

  "Where did you hear them?"

  Hessa hesitated, then sighed. "My nephew works security at one of the transit hubs. He sees a lot of military movement. He mentioned seeing a Thunderhawk transport land two days ago. Green and black livery. Salamanders colors."

  Sister Mercy felt a spark of hope. "Which hub?"

  "Tertius Station. But Miriam, you can't just approach a Space Marine. They don't—"

  "I know. Thank you, Hessa. Emperor bless you."

  She left before the old woman could protest further.

  The journey to Tertius Station took hours.

  Sister Mercy moved through the hive's lower levels, using contacts she'd built over years of service.

  A former orphan who'd become a transit worker gave her directions through maintenance tunnels.

  A medicae she'd assisted during a plague outbreak provided her with credentials to pass certain checkpoints.

  A Steel Legion sergeant whose daughter she'd personally cared for offered her an escort through a particularly dangerous district.

  Every favor called in. Every bit of goodwill accumulated over decades of kindness, now spent in a single desperate night.

  By the time she reached the upper hive, her legs ached, her lungs burned despite the rebreather, and exhaustion pulled at her like gravity.

  But she didn't stop.

  The District's Great Cathedral loomed before her—a massive structure of stone and steel, its spires reaching toward the smog-choked sky. It served the upper hive's elite, its halls filled with gold leaf and incense, a stark contrast to the modest shrine at the orphanage.

  Sister Mercy had never been inside before. She'd heard stories, of course. Every Ministorum sister had.

  But tonight, she didn't care about propriety or station.

  She pushed through the heavy doors.

  The interior was vast. Vaulted ceilings disappeared into shadow. Stained glass windows—rare and precious in a hive city—cast colored light across rows of pews. And at the far end, before a towering statue of the God-Emperor in His full glory, stood a figure.

  A Space Marine.

  The crowd that had been present for evening prayers had pressed themselves against the walls, giving the Astartes a wide berth—at least fifty feet in all directions. No one dared approach. Children clutched their parents. Even the priests who should have been conducting the service stood frozen in awe and terror.

  He wasn't guarding the statue.

  He was praying.

  Motionless as the stone Emperor above him, the Space Marine knelt in supplication, his massive armored form impossibly still. Green ceramite plates caught the candlelight. A flamer was mag-locked to his back. His helmet rested on the floor beside him, revealing dark skin and eyes that glowed like embers.

  Sister Mercy felt her breath catch.

  But she didn't hesitate.

  She walked forward, her footsteps echoing in the cathedral's silence.

  Gasps rippled through the crowd. A guard shouted, "Halt! You cannot—"

  Sister Mercy ignored them all.

  She crossed the invisible barrier the crowd had created and threw herself at the Space Marine's feet, her knees hitting the stone floor hard enough to bruise.

  "Lord Astartes!" she cried out, her voice breaking. "Please! I beg you! A child is dying and only you can help her!"

  The Space Marine moved.

  Servos growled. Armor plates shifted with mechanical precision. He rose to his full height—nearly three meters tall, a god of war carved from metal and flesh.

  His glowing red eyes turned down to look at her, and Sister Mercy felt the weight of that gaze like a physical force.

  He didn't look like a man at prayer. He looked like death incarnate, capable of breaking her in half with a casual gesture.

  Guards rushed forward, lasguns raised, shouting for her to get back, to not approach the Astartes—

  But the Space Marine raised one massive gauntleted hand, and everyone froze.

  His voice, when he spoke, was deep and resonant, carrying easily through the vast cathedral.

  "You interrupt my communion with the Emperor." Not a question. A statement of fact.

  Sister Mercy's entire body trembled, but she forced the words out. "I am Sister Mercy of the Adeptus Ministorum. I serve at Saint Celestine Orphanage. And there is a child dying—a child who needs help that only a son of Vulkan can provide."

  The Space Marine stared down at her for a long moment.

  Then, impossibly, his expression softened.

  "Rise, sister. The Emperor hears all prayers, even those delivered with desperation rather than reverence."

  Sister Mercy stood on shaking legs.

  The Space Marine studied her, and something in his glowing eyes shifted—recognition, perhaps, or respect.

  "Speak," he said. "Tell me of this child. And I will judge if my aid is warranted."

  The next morning, the orphanage was in chaos.

  Sister Mercy's absence had been discovered at dawn prayers. Her cell was empty, her bed neatly made, her robes folded but her person gone.

  The younger sisters were panicking. Sister Marian was tight-lipped and worried. And Sister Prudence...

  Sister Prudence sat in her office, staring at the empty chair across from her desk, her expression unreadable.

  A junior sister knocked hesitantly. "Sister Prudence? Sister Mercy is still missing. Should we... should we inform the Ecclesiarch?"

  Sister Prudence was quiet for a long moment.

  Then she said calmly, "If she returns by nightfall, I will punish her myself for abandoning her duties. If she does not return by nightfall, I will report her disappearance to the Ecclesiarch as a dereliction of her vows."

  The junior sister nodded and left.

  Sister Prudence returned to her paperwork, but her hands trembled slightly as she wrote.

  Come back, you foolish woman. Please come back.

  Afternoon came.

  Sister Prudence was conducting lessons when the door to the classroom opened.

  Sister Marian stood there, her face flushed, breathing hard.

  "Sister Prudence. You need to come. Now."

  "I am in the middle of—"

  "Now."

  The tone left no room for argument.

  Sister Prudence dismissed the children and followed Sister Marian into the hallway.

  And stopped dead.

  Sister Mercy stood at the end of the corridor.

  Dirty. Exhausted. Her civilian clothes torn and stained.

  But alive.

  And beside her...

  Sister Prudence's breath caught.

  A Salamander Space Marine.

  He had to duck through the doorway, his massive armored form barely fitting in the orphanage's corridors. His presence filled the space, making everything else seem small and insignificant by comparison.

  Sister Prudence, who prided herself on maintaining composure in all situations, found herself utterly speechless.

  Sister Mercy managed a weak smile. "I found help."

  Before Sister Prudence could respond, Sister Marian pushed past them.

  "That's wonderful, truly, but we have a more immediate problem. Something's happening to Lilith. I don't know if it's good or bad, but you need to see this. Now."

  The four of them rushed through the corridors—two sisters, one Astartes, and one very confused Sister Prudence—toward the medicae ward.

  Sister Marian threw open the door.

  And they all stopped.

  Lilith lay on the cot, still unconscious, still burning with fever.

  But now she was burning with something else too.

  Flames.

  Gold flames.

  They wreathed her small body, dancing across her skin without consuming it. Not fire in any natural sense—this was something else. Something that didn't burn or harm, just was.

  The air around her shimmered with heat that didn't actually heat. The light cast strange shadows that moved independently of any source.

  And Eve—

  Eve knelt beside the cot, gripping Lilith's hand with both of hers, her face twisted in panic.

  "It's hurting her," Eve said, her voice breaking. "The fire—it's burning her—I don't know what to do—"

  But Lilith's skin showed no burns. No damage. The flames licked across her flesh gently, almost lovingly, as if protecting rather than destroying.

  Sister Marian approached slowly, her medicae training warring with her religious awe.

  "It's not hurting her," she said softly. "Look. No burns. No blisters. Her breathing is... actually steadier than before."

  The Salamander stepped forward, his massive form filling the doorway.

  His hand moved instantly to the flamer mag-locked to his back, the weapon's nozzle glowing with heat as he brought it to bear.

  "Stand back," he commanded, his voice hard as ceramite. "Warp manifestation. The child must be purged before—"

  But he stopped.

  His glowing red eyes narrowed, studying the flames more closely. Slowly—so slowly it seemed to take an eternity—he lowered the flamer.

  "No," he said, his voice filled with something like wonder. "This is... not the Warp."

  "How can you tell?" Sister Marian asked, her voice shaking.

  The Salamander took a step closer, his armored boots heavy on the medicae ward floor.

  "The Warp is ice and hatred," he said, his tone absolute. "When daemons manifest, when psykers draw upon the Immaterium, it brings cold. A chill that seeps into the soul. Warp-fire may look like flame, but it freezes as it burns. It consumes warmth and hope, leaving only ash and despair."

  He gestured at Lilith, at the golden flames dancing across her small form.

  "This fire is warm. Pure. I can feel it from here—not heat that burns the flesh, but warmth that... comforts."

  His gaze shifted to Eve, still kneeling beside the cot, still gripping Lilith's hand.

  "And look," he noted, pointing a massive gauntleted finger. "The fire touches the other child, yet leaves no mark. Warp-fire would have consumed her arm by now. This flame... it knows its target. It protects."

  He knelt—an act of humility stunning in its rarity—bringing himself closer to their eye level.

  "This is not corruption," he said with finality. "This is something else. Something I do not understand. But it is not the enemy."

  Eve looked up at him, tears streaming down her face. "Save her. Please. I don't know what's happening. I don't know what to do."

  The Salamander's glowing red eyes met hers, and his expression softened.

  "Peace, child. Your sister lives. And these flames are not harming her—they are healing her."

  He reached out slowly, his massive gauntleted hand hovering over the golden fire.

  "I am a son of Vulkan. I know the nature of flame—its fury, its mercy, its power to destroy and to forge anew. And I tell you truly: this fire means your sister no harm."

  He stood, his massive form casting a shadow across the entire ward.

  "But I will help her. You have my word, as a Salamander and a servant of the Emperor."

  Eve stared up at him, then looked back at Lilith.

  The golden flames continued to burn.

  And somewhere, in the space between consciousness and oblivion, Lilith began her journey back.
