Threnody tried to move, but the body would not respond. Muscles trembled with exhaustion. Magic burned through depleted reserves. Everything hurt in ways she was still learning to process.

  Vesper’s consciousness surfaced through the pain, sharp and immediate and filled with something that wasn’t relief. Threnody felt it pulse through their shared body. Fear.

  You unmade him, Vesper whispered. I watched you tear his soul apart piece by piece until there was nothing left. Like he’d never existed at all.

  “He was corrupt. You know what he was. What he would have done.”

  I know. The Resonant’s fear didn’t lessen. I know he deserved it, but you didn’t just kill him. You erased him…and you could do that to anyone.

  Threnody understood then. This wasn’t about Tenebrae. This was about everyone else. About Rafe. About Blair. About every mortal soul Vesper loved.

  “Yes,” Threnody said. “I could.”

  Please don’t…

  Threnody forced the body to breathe. In and out. Steady and controlled despite the agony. They were lying on cracked earth, surrounded by ruins. Smoke and dust filled the air. Magic crackled across broken ground.

  She tried to sense the other Arcana, but her power was depleted. The unmaking had cost more than she anticipated. It would take time to recover. Time they might not have.

  Threnody forced Vesper’s body upright, ignoring the screaming protests in every muscle. They couldn’t stay here, not when Fermata and Fortis sought her.

  Threnody stood on shaking legs, borrowed hands braced against broken stone. She looked out at the devastation surrounding them. The city was torn apart. Buildings had collapsed, the ground was torn apart, and the storm from her merging still circled in the fractured sky.

  She had done this. The cost of freedom was measured in destruction and Vesper had witnessed all of it. This was her legacy.

  I feel thin, Vesper whispered, and Threnody heard the question beneath the words. How long will I remain?

  Threnody said nothing. She didn’t know if Vesper’s consciousness would fade gradually or vanish all at once. The Resonant was a temporary passenger in a body that no longer belonged to her. That was simply the nature of what Threnody was. Arcana did not share vessels. They consumed them.

  She forced the body forward, each step agony. They needed time to recover before the next battle came…because it would come. Fermata and Fortis wouldn’t stop. They wanted her power just as Tenebrae had, and when they found her, she would have to unmake them.

  Vesper’s consciousness was quieter now. Threnody felt it and wondered if she should care.

  But she was free and realised, that she did not.

  Chapter 14

  Blair left Cormac’s room and moved through the narrow hallway. The building settled around her with creaks and groans that sounded too much like voices in the dark.

  She couldn’t sleep. Every time she closed her eyes, she saw Theo’s face, heard Faith’s scream, remembered the empty space where they’d stood before the ritual turned them to dust. There was no time left. No more planning, no more waiting. If Vesper was anywhere in this broken city, Blair had to find her now.

  Aldrick’s door was closed, but light flickered beneath it. Blair knocked twice and pushed it open without waiting for an answer.

  He looked up from the maps spread across his table.

  “I need you to teach me,” Blair said.

  Aldrick studied her for a long moment before gesturing curtly to the chair across from him. “Sit.”

  Blair sat and placed her hands flat on the table. Her magic pulsed beneath her skin, still new, still alien, and still growing into something she wasn’t sure she could contain.

  “Your magic is unpredictable,” Aldrick said flatly. He moved the maps aside. “If you reach too far or push too hard, it could fracture something inside you that won’t heal. Resonant magic responds to the fundamental patterns of reality. If you lose yourself in the ley lines, you might not find your way back.”

  “Then you’d better teach me properly.”

  Aldrick’s expression didn’t change. He stood and moved to the window, looking out at the grey sky that stretched over the ruined city. “The ley lines are the pathways magic flows through. Here, they operate differently than the outside world. They have been reshaped, regimented, and bound. They connect everything in Nightreach, every ward, every spell, every enchantment. Right now, they’re broken, but they still carry echoes of what moves through them.”

  “Like Vesper.”

  “Like the Echo.” Aldrick turned back to her. “Your artificial nature makes you sensitive to Resonant signatures. We can now surmise that the Echo’s awakened signature is more Resonant-like than it was when it was bound in stone. You should be able to feel her presence if she’s anywhere in the city, but you’ll need to reach out carefully. Let the magic guide you instead of forcing it.”

  Blair flexed her fingers. The opalescent shimmer beneath her skin was faint, barely visible in Aldrick’s mage light. “How do I start?”

  “Close your eyes. Breathe. Feel the magic inside you, then reach outward. Not with your hands, but with your awareness. Feel for the ley lines beneath the city. Can you do that?”

  “Yes. I’m not a complete idiot.” Blair closed her eyes and let her breath come slow and steady. The magic pulsed beneath her skin like a second heartbeat, artificial and wrong but present nonetheless. She’d spent days ignoring it, pushing it down, refusing to acknowledge what Tenebrae had turned her into. Now she let it rise and extend outward into the darkness, using his tool against him.

  At first, there was nothing but the sounds of the safehouse settling around them and the distant drip of water through damaged pipes. Then she felt it.

  A network of pathways stretching through Nightreach like veins through a body. Broken threads of magic that pulsed and flickered with dying light. Some were strong, others barely whispers of what they’d once been. The chaos of it hit her all at once, too much information, too many fractured connections bleeding into each other and creating a cacophony that made her head spin.

  “Don’t fight it,” Aldrick murmured from somewhere far away. “Let it flow around you. You’re looking for something specific. A signature. Opalescent light that feels like sunlight through crystal.”

  Blair focused and tried to filter through the chaos. The ley lines twisted and coiled through the city, most of them dark and damaged beyond recognition. Others pulsed with strange energies she didn’t understand, residue from the merge or the titan’s rampage on the Darkmese. She searched for anything that felt like Vesper, any trace of that opalescent shimmer that marked Resonant magic.

  Nothing.

  She pushed further and reached deeper into the network. The magic inside her responded, stretching outward. She felt the edges of broken wards, the remnants of shattered spells, the lingering traces of battles fought and lost across the city.

  Still nothing.

  Blair’s frustration built and pressed against her chest. She was missing something. Vesper was out there somewhere, trapped inside her own body with a divine consciousness trying to erase her from existence. She had to be alive. She had to be fighting because that’s who Vesper was.

  Blair had to find her. She had to reach her before Fermata and Fortis did, before the other Arcana could claim the Echo’s power for themselves.

  The shockwave hit without warning.

  It ripped through the ley lines in a wave of raw power, and Blair gasped as the force of it slammed into her awareness. The entire network convulsed with magic surging and recoiling in waves that made her stomach lurch and her hands grip the edge of the table.

  Then came the vision.

  Disorienting and fragmented, like looking through broken glass that cut at her mind. Blair saw a pocket of space folded away from reality, and she recognised the sensation immediately. She’d been in one before with Rafe when they’d met the Nightweaver. That same strange pressure against her skin, that same feeling of being nowhere and everywhere at once, suspended in a place that shouldn’t exist.

  But this space was collapsing.

  Two figures stood at its centre. One was Vesper, but not Vesper. Her eyes burned with silver light that seemed to pierce through the vision itself, and her body radiated power that made Blair’s artificial magic recoil in recognition and terror. The Echo, fully awakened.

  The other figure was Tenebrae, the Nightweaver himself.

  Blair watched as Vesper raised her hand, watched as shadow magic tried to bind her, to contain her, to force her into submission. The shadows writhed and coiled around the Echo, but they couldn’t touch her. Tenebrae’s power simply slid off her skin. He was an Arcana, a being who’d survived millennia, who’d manipulated Nightreach for centuries, who’d turned Blair into this artificial thing with barely any effort.

  And he was nothing to the Echo.

  She moved, and reality bent around her. Blair felt it through the vision, felt the laws of existence twist and break at the Echo’s will. Tenebrae tried to resist. His shadow magic flared, building into a wall of darkness that should have been impenetrable. Blair had seen what his power could do. She’d felt it wrap around her during the ritual, felt it crystallise Theo and Faith, felt it hold Vesper captive.

  It meant nothing.

  The Echo moved, and Tenebrae unravelled.

  His form came apart, breaking down into pieces that ceased to have meaning. Shadow magic dissolved and his physical presence fragmented. The silver light in his eyes flickered once, then went dark. One moment he was there, solid and real, an Arcana who’d walked the earth since before human civilisation began. The next, he was gone. Erased from reality as if he’d never been born, as if millennia of existence could be snuffed out with a thought.

  There was no ceremony to it. No final words. No chance to bargain or flee or even scream.

  He was just…gone.

  Horror flooded through Blair’s chest and stole her breath.

  This was what the Echo could do. This was what awaited them if Blair failed. She’d spent days trying to convince herself they had a chance, that her plan to bargain with the Echo made sense, that she might remember mercy. But watching Tenebrae simply cease to exist stripped away every comforting lie she’d told herself.

  They had no chance. No leverage. No way to fight or resist if the Echo decided humanity wasn’t worth saving. Blair was leading Praxis to certain death, and they would die the way Tenebrae had.

  They would cease to be, as if they’d never existed at all.

  This was what awaited them. This was what would happen to humanity if she couldn’t convince the Echo to spare them. Just the absolute erasure of everything they were, everything they’d built, everything they might have become.

  Then the liminal space shattered. Reality tore open and Blair felt the explosion ripple outward through the ley lines in waves of raw power that made the fractured network buckle. The shockwave spread across Nightreach, tearing through what remained of the city’s magical infrastructure.

  Blair pulled back hard.

  She gasped and opened her eyes, her hands gripping the edge of the table so tight her knuckles had gone white. Her heart pounded as sweat dampened her temples and trickled down her spine. The room spun around her, solid and real but feeling wrong after what she’d just witnessed, as if the vision had stripped away some layer of perception she couldn’t quite name.

  “Blair.” Aldrick’s voice cut through the disorientation. His hand was on her shoulder, steady and grounding, pulling her back to herself. “What did you see?”

  “Tenebrae.” The word came out rough, scraped raw from her throat. “He’s dead.”

  Relief should have flooded through her at those words. The Arcana who’d manipulated her, who’d turned her into this artificial thing, who’d orchestrated Theo’s death and Faith’s and countless others was gone. But all Blair could feel was the terror of watching him cease to exist, the absolute certainty that this was humanity’s fate if they failed to reach the Echo in time.

  “The Echo is loose,” she added, her voice shaking despite her best efforts. “She’s in the city.”

  Aldrick’s expression darkened. “Are you certain?”

  “I saw her break free. She unmade Tenebrae like he was nothing.” Blair looked up at Aldrick. “We’re nothing to her. She could erase us all and not even notice we were gone.”

  “Then we need to move fast.”

  Before Blair could respond, footsteps thundered down the hallway outside. The door burst open, and Reed stood in the doorway, breathing hard, his face pale in the mage light.

  “The sky just split open,” he said without preamble. “East side of the city. Half the agents are panicking.”

  Blair was on her feet immediately, her chair scraping against the floorboards. “Where exactly?”

  “I don’t know exactly. Just east.”

  A tremor shook the safehouse and Blair grasped the table as dust rained down from the ceiling. “Damn it,” she muttered.

  “There had to have been an anchor,” Aldrick said, looking out the window.

  “An anchor to what?” Reed demanded.

  Aldrick grunted in annoyance. “A liminal space. Where Tenebrae was holding the Echo.”

  Reed’s eyes widened. “Was?”

  Blair inhaled sharply. It had to be the Spirefields. That’s where the Echo was imprisoned when Nightreach was created, where the seven mages had built the city’s magical foundations, the Fold, everything.

  The Spirefields was the heart of the city, so it was the perfect place for Tenebrae to anchor is own prison. That’s where she needed to go. That’s where she’d find the Echo.

  This wasn’t like the other fights. This wasn’t like facing the titan or surviving the sanctum collapse or even watching Theo and Faith die. This was walking deliberately towards a being who could erase her from existence with barely a thought.

  But what choice did she have? Hide in the safehouse and wait for the Arcana to reshape reality? Watch humanity die slowly instead of quickly? Theo had believed they could be saved. He’d died believing it. Blair owed it to him to try, even if trying meant her own death.

  “The Spirefields,” she said. “Rafe’s ancestral home.”

  Aldrick’s expression sharpened. “The last place of power in a broken city.”

  “Rafe might be drawn there too,” she added. “If he’s anywhere in Nightreach and felt that shockwave…”

  “He would. For Vesper…he would.” Aldrick’s tone was dismissive, matter-of-fact. “His core is depleted. If he encounters the Echo in her current state, he won’t survive the meeting.”

  Blair looked at Reed. He’d fought at her side, through every nightmare this city had thrown at them. He was waiting for her decision, trusting her to lead even now.

  “I have to go,” Blair said. The words felt inevitable, the only path forward. “I have to find the Echo and Rafe before it’s too late. Before Fermata and Fortis move on her. This is our one chance to save what’s left of our world.”

  Reed didn’t hesitate. “I’m with you.”

  “Do you understand what we’re walking into?” Blair studied his face, searching for doubt. “We might not come back from this. I just saw the Echo kill an Arcana like she was squashing a bug. She could do the same to us.”

  “We’re dead if we don’t try.” Reed’s voice was steady, matter-of-fact. “The world’s ending, Blair. At least this way we go down fighting for something instead of hiding in the dark waiting to die.”

  Blair’s throat tightened. She nodded once, then turned to Aldrick. “I gather you’re coming, old man.”

  “Of course.”

  “Get whatever you need. We leave in ten minutes.”

  Aldrick picked up his coat without comment. It was all he had.

  Blair took a breath and let it out slowly, then looked at Reed. “Go downstairs. Tell the others we’re moving out. I need to speak with them before we leave.”

  Reed nodded and left the room, his footsteps echoing down the hallway.

  Blair moved to the window and looked out at the grey sky stretching over Nightreach. In the distance, she could see a tear in sky. Purple light bleed through the wound in reality, pulsing with power that made her artificial magic sing in recognition. The place where the Echo had broken free from Tenebrae’s prison and emerged into the world.

  “Looking at it won’t change the situation,” Aldrick drawled.

  She turned away from the window. “What do I even say to a god?” She snorted at the irony. “That’s what the Echo is, right? A literal god?”

  “She is the same as all of us, Blair. She is merely a soul who has access to immense power.” His eyes narrowed. “You’ll get yourself killed with that attitude.”

  “Probably.” Blair moved towards the door. “But it’s our only option. We can’t fight the Arcana. We can’t hide from them. The only thing we can do is try to convince the Echo that we’re worth saving, that humanity deserves another chance.”

  “Foolish.”

  Blair paused in the doorway and looked back at him. “Then don’t come.”

  “I didn’t say I wouldn’t.” Aldrick’s expression was unreadable. “But if you talk to her like she is a god, then you’ve already lost, girl.”

  Blair glared at the old mage, understanding why Rafe wanted to come to Nightreach in the first place. “The last thing I’m going to do is let you speak for humanity.”

  She left the room and moved through the narrow hallway towards the stairs. The building was stirring around her, voices rising in alarm and confusion. The agents had felt the ground shake and the sky tear open for a second time. They knew something had changed, that the endgame was finally upon them.

  Blair descended the stairs and entered the main room where the remaining Praxis agents were gathered. Reed stood near the door, waiting. Barnes and Sienna were checking their weapons. Denny limped between the injured, offering reassurance. Edmund lingered beside Finley, whose head was still bandaged.
