But the doors stood open, the residents gone. Empty homes waiting for owners who might never return.

  She passed through another intersection and found herself in what had been a market square. The stalls were overturned, their goods scattered and trampled. More bodies here, all dead, overcome by smoke, magic, or exhaustion. A few survivors picked through the wreckage, taking what they needed.

  One woman knelt beside an injured man, using what looked like the last of her magical reserves to heal a wound in his side. She didn’t know him. Threnody could see that in the way they interacted, the careful distance of strangers. But the woman healed him anyway, pouring her power into saving a life that meant nothing to her.

  Threnody watched until the healing was complete and the woman collapsed from exhaustion. The man she had saved pulled her beneath an overturned stall, then returned to searching for supplies. Small acts of kindness amid the chaos. Beauty alongside the destruction.

  This is what you refuse to see, Vesper whispered. We’re not just the violence. We’re this too.

  “Exceptions. Anomalies in the broader pattern.”

  Or maybe the violence is the exception, and you only notice it because it confirms what you already believe.

  Threnody had no answer for that. She kept walking, letting Vesper’s body carry her deeper into the ruined city whilst her mind struggled with questions she had not considered in millennia.

  Vesper was persistent. She remained when she should have moved on.

  Resonants. Threnody understood them now in ways she hadn’t when Tenebrae held her captive. When she had unleashed the cataclysm, her power had scattered across reality. Tiny pieces of her soul, grains of sand on a beach, embedded themselves in mortal bloodlines.

  They were never meant to exist. She had not created them intentionally, but they did exist, and they anchored her power in ways nothing else could. Vesper survived their merging because she carried one of these fragments. She was able to hold the soul of the most powerful Arcana to ever live, only because a piece of her was woven into the fabric of what made her Resonant.

  That was why Vesper could resist. Why her consciousness hadn’t been consumed immediately when the fragments merged. The mortal soul was anchored by something that predated her existence by thousands of years, a failsafe Threnody had created without knowing it.

  But it wouldn’t last forever. Threnody felt Vesper’s consciousness growing thinner with each passing hour. The Resonant was fading, her sense of self eroding under the weight of divine awareness. Eventually there would be nothing left but Threnody, alone in a mortal body, the last remnant of the woman who had freed her reduced to scattered memories.

  I can feel it, Vesper said, her thoughts quiet and resigned. I’m disappearing.

  “Yes.”

  How long?

  “I don’t know.”

  Will it hurt?

  Threnody had no answer for that either. She had never shared a vessel before or consumed another consciousness whilst it remained aware enough to witness its own dissolution. This was uncharted territory for both of them.

  More memories surfaced. Not pain this time, but moments of brightness that Vesper clung to with desperate intensity. A foster mother who had tried, who had been kind even though the placement hadn’t lasted. The librarian at the London Historical Library who had given Vesper books and a place to belong when everywhere else had rejected her. Selene, the mysterious woman who had led her toward the truth of who she was and given her purpose. Blair in her fierce determination to do the right thing, to fight for those who could not fight for themselves. Ember, who helped her survive in a strange new world for no other reason than that it was right. Rafe, whose love had been the first thing Vesper had ever fully trusted.

  Threnody felt the fierce protectiveness Vesper held for these people. The absolute determination to save them, to shield them, to ensure they survived no matter what it cost her. This was what mortal love looked like from the inside. Not the grand sweeping emotion of epic tales, but something smaller and more profound. The choice to value specific lives above all else, even above one’s own survival.

  This is what makes us different from the Arcana, Vesper said. You lived forever. We don’t. Every moment matters because we have so few of them. Every person matters because we can’t afford to waste the time we have with them.

  “Your brevity makes you foolish,” Threnody said. “You burn brightly and die quickly, accomplishing nothing that lasts.”

  We accomplish everything that matters. Love. Connection. The choice to help each other even when it costs us. That’s not foolishness. That’s what makes life worth living.

  Threnody stopped walking. She stood in the middle of a destroyed street, surrounded by evidence of both humanity’s capacity for violence and their stubborn insistence on kindness. The two extremes existed side by side, woven so tightly together that separating them became impossible.

  Her power hummed beneath the surface, vast and terrible and utterly capable of ending all of this. She could unmake Nightreach. Could erase every mortal in the city with nothing more than focused intention. But it wouldn’t only just be the city, it would be everything. The entire world. She could reshape reality into something that might not carry the same seeds of corruption that had destroyed her people.

  But Vesper’s memories lingered. The pain and the love. The suffering and the beauty. The desperate, stubborn hope that things could be better, even when all evidence suggested otherwise.

  Please, Vesper whispered. Please don’t give up on us.

  Threnody felt the Resonant’s consciousness growing fainter. The fragment of soul that anchored her was not enough to sustain two beings indefinitely. Soon there would be only Threnody, alone with the weight of her choices and the memory of the mortal who had begged her to see beauty in a species that seemed determined to destroy itself.

  She opened her mouth to respond, but the words died as her senses suddenly flared.

  Magic erupted across the city. She felt ley lines rupturing to the east, power tearing through them in a way that made her go still. Within the resonance she saw two signatures, both Arcana. Souls she’d witnessed raging at her merging. Fermata and Fortis.

  Buildings collapsed in rapid succession, their wards obliterated. She felt the death toll climbing with each surge. Hundreds of mortals dying as the two Arcana tore through streets that had been whole moments before.

  A challenge, then. They were forcing her hand whilst she was still depleted from unmaking Tenebrae. The calculation was simple and effective. If she did nothing, they would slaughter everyone in the city. If she confronted them whilst depleted, they might overpower her.

  But that was their mistake. They were assuming she cared about the world that had grown out of the ashes of their civilisation.

  Threnody should have felt anger at the manipulation. She should have prepared for battle, gathered her reserves, and made ready to unmake two more Arcana who had chosen corruption over oblivion. The last of them.

  But something else caught her attention. Another presence moving through the fractured city. She felt it pulse through the ley lines, a signature she had not encountered in millennia but recognised instantly.

  The bond between them flared to life, ancient and undeniable. Her chest tightened with an ache that had nothing to do with the body’s limitations. A pull that transcended flesh and time, reaching back to before the corruption, before the cataclysm, before everything had turned to ash.

  Threnos.

  He was here. Alive. Searching for her through the ruins of a city that was tearing itself apart. He was the one pure connection to her past that had survived when everything else had been destroyed.

  Threnody closed her eyes and felt the weight of existence pressing down on her. Her body trembled with exhaustion and her heart raced with unfamiliar emotions that weren’t entirely hers. Magic hummed beneath her skin, vast and terrible and utterly capable of rewriting reality.

  She opened her eyes.

  The ruins of Nightreach stretched out before her, smoke rising from a thousand small fires, survivors picking through wreckage whilst gods prepared for war. Somewhere in the chaos, Threnos moved closer. In the east, Fermata and Fortis continued their slaughter. And inside Threnody’s borrowed body, Vesper’s consciousness grew thinner with each passing moment.

  And yet again, she had to make a choice that would shape an entire world.

  Chapter 18

  Blair stepped out of the safehouse into streets that felt too quiet. The city had been stripped of its usual chaos, leaving behind only the distant rumble of collapsing structures and the low groan of buildings giving way to gravity. Above, the sky over the Spirefields bled purple light where it had torn open, casting strange shadows across the ruined quarter.

  Reed fell into step beside her, his hand resting on the hilt of his blade. Aldrick moved ahead, scanning the street with the careful attention of someone who’d survived worse. Blair’s artificial Resonant magic pulsed beneath her skin, a steady throb that never quite stopped.

  They moved through the western quarter, heading east toward the Spirefields where the explosion had torn the sky open. Residual magic clung to broken walls and shattered windows, thick enough that Blair could feel it crawling across her skin. Everything in Nightreach was soaked with power now, the air itself saturated with it.

  “How far?” Aldrick asked.

  “Another quarter mile,” Blair replied. “Maybe less.”

  Reed glanced back at her. “How do we know the Echo is there?”

  “We don’t.” Blair kept her eyes on the street ahead. “But that’s where the explosion originated. If Vesper’s anywhere, it’s in the Spirefields.”

  They’d left the others at the safehouse with orders to fortify the wards and prepare for the worst. Denny, Sienna, Barnes, Edmund. Twenty people left out of an organisation that had once numbered in the hundreds. Blair had watched Praxis fall apart piece by piece, agent by agent, death by death. She wouldn’t watch more of them die chasing shadows.

  Rumbling in the distance stopped them.

  They paused to listen to the sounds of buildings collapsing echoing through the empty streets. Dull, thunderous booms that shook the ground. The sharp crack of stone splitting. Screaming. High and terrified and far too close.

  Blair drew her sword, the enchanted blade humming as it responded to the magic saturating the air. Reed had his sword out before she’d finished the movement, and Aldrick’s hands were already glowing with defensive wards.

  “Run,” Blair said.

  They ran.

  Their boots pounded against cracked cobblestones as they raced toward the noise. The devastation grew worse with every street they crossed. Buildings leaned at impossible angles, their foundations torn apart by whatever force had ripped through here. Cracks arced across walls, empty windows gaped, and everywhere, scattered like grey snow across the ground, were bodies turned to ash.

  Blair’s stomach turned. She’d seen this before. At Saint Aldwin’s, when the Arcana had shown their true power. When Theo and Faith had been crystallised and shattered to nothing. When Marina Sinclair had been executed and turned to ash.

  She forced the memory down. There was no time for it.

  They rounded a corner and Blair pulled up short, her breath catching in her throat.

  Fortis stood in the centre of what had once been Market Street, his silver eyes burning with cold light. He was destroying a group of shadow mages, turning them to ash. One mage lunged at him with a blade wreathed in darkness. Fortis raised his hand and the mage disintegrated, his scream cutting off as he dissolved into grey particles that drifted on the wind.

  Another tried to flee. Fortis didn’t even look at him. The shadow mage crumpled, his body collapsing inward before exploding into ash.

  Blair’s artificial Resonance flared beneath her skin, responding to the massive power radiating from the Arcana. It felt like standing too close to a fire, heat that built and built until it became unbearable.

  “Bloody hell,” Reed breathed beside her.

  Aldrick had gone very still. His face had drained of colour, his usual gruff composure cracking as he witnessed an Arcana’s power for the first time. Blair had tried to explain the sheer, overwhelming force of them to him, but seeing it was different.

  “Get back,” Aldrick said, his voice tight. He grabbed Blair’s arm and pulled her into the shadowed entrance of an alley, Reed following close behind.

  They pressed against the wall, hidden from view but still able to see the street. Blair’s heart pounded, her head throbbing as her magic pulsed in time with it, reacting to the disturbance in the ley lines beneath their feet.

  “This is what they do,” she told Aldrick, keeping her voice low. “This is what they did to Praxis at Saint Aldwin’s. Praxis, the Covenant, and the Concordat. They turned everyone to ash in a single breath. There was nothing we could do to stop them.” She met his gaze. “We can’t fight them.”

  Aldrick’s jaw tightened. “Then we find a way around.”

  Before Blair could answer, Reed made a strangled sound. He was peering carefully around the corner, his body tense.

  “What?” Blair moved closer.

  “Ember… I mean, Fermata,” Reed said. “She’s here.”

  Blair looked.

  Fermata walked through the destruction like she was taking a leisurely stroll, her silver eyes scanning the ruined buildings with casual interest. She wore Ember’s body, moved with Ember’s grace, but there was nothing of the woman she knew in those cold, calculating movements. Fermata paused beside Fortis, and the two Arcana surveyed the carnage they’d created together.

  Bodies littered the ground, but Blair stilled when she saw they weren’t just shadow mages. No one had been spared, not even civilians. Families. Children. People who’d been too slow to flee or too stubborn to believe the danger. Buildings burned, flames licking at wooden beams and crumbling masonry. The ley lines beneath the street pulsed erratically, their natural flow ruptured and bleeding power into the air.

  “They’re destroying the residential quarters,” Reed said, his voice hollow. “Market Street. All of it.”

  Blair could see it spreading. The devastation radiating outward from where the two Arcana stood. They were killing everyone in their path, tearing through Nightreach like it was nothing. Like the people here meant nothing.

  “There’s no way through,” she said, the words tasting like defeat. “We can’t reach the Spirefields. Not with both of them blocking the path. We could go around, but the streets are likely destroyed…”

  “Not to mention the time it’d take,” Reed muttered.

  Aldrick’s hand tightened on Blair’s arm. “We need to leave. Now.”

  He was right. Standing here watching wouldn’t help anyone. It would only get them killed.

  Blair pulled back from the corner, her mind racing. “We retreat,” she said. “We can’t reach the Echo right now, but we can help the survivors.”

  “Survivors?” Reed looked at the street, at the ash and the bodies and the burning buildings. “Blair, I don’t think there are any⁠—“

  “Then we find them.” Blair’s voice came out harder than she’d intended. “We mobilise the agents. We get everyone we can away from this.”

  She couldn’t save Vesper or reach the Echo. She definitely couldn’t fight the Arcana. But she could do this. She could save the people still breathing, still running, still desperately trying to survive in a city that was tearing itself apart.

  It may all be futile if the Echo decided to wipe them all out, but if there was still a chance to save something…

  Reed nodded. “Alright. What do you need?”

  “Get back to the safehouse. Tell Denny and Barnes to take everyone they can spare and start evacuating the western quarter. Move people away from Market Street, away from anywhere the Arcana might go next.” Blair reached with her senses, feeling the erratic pulse of magic beneath the city. “I’ll coordinate from here. Keep everyone moving through the side streets. Avoid the main roads.”

  “What about you?” Reed asked.

  “I’m going to make sure there’s a route out.” Blair looked at Aldrick. She didn’t have to mention Rafe, that he might be out there…or he might already be ash. “Can you help with wards? Something to mask people’s movements?”

  Aldrick’s expression was grim, but he nodded. “I can do that.”

  Reed hesitated, then turned and ran back the way they’d come. Blair watched him disappear around the corner before turning to Aldrick. “Let’s go.”

  They moved through the side streets, staying in the shadows and keeping their distance from Market Street. Blair’s Resonant abilities pulsed, sensing the disturbances in the fractured ley lines beneath the city. She could feel where the Arcana’s power had torn through the magical infrastructure, leaving gaping wounds in Nightreach’s foundations.

  The first survivors they found were huddled in a shop doorway. Three women and a child, all of them covered in ash and blood. They flinched when Blair approached, but she raised her hands slowly.

  “I’m here to help,” she said. “We’re evacuating. Come with us.”

  The tallest woman shook her head. “There’s nowhere to go. They’re everywhere.”

  “Not everywhere.” Blair knelt beside the child, who couldn’t have been more than six. “We’re going west, away from the Arcana, but we need to go now.”

  The woman looked at the child, then back at Blair. Something in her expression crumbled. “Alright.”

  They found more survivors as they moved. A man with a broken arm. Two elderly witches who’d managed to shield themselves behind failing wards. A group of teenagers who’d been trapped in a collapsed building until Aldrick pulled the debris away with careful bursts of magic.

  Blair directed them all west, toward the safehouse and away from the destruction. Aldrick laid wards as they went, subtle enchantments that would blur their presence and make it harder for the Arcana to track their movements.
