Two days had passed since they discovered the Brilliance Tree's ability to push back the fog. Jin stood at the window, watching the pale light of a sunless morning struggle through the gray. Simon had broken through to First Order Mid the previous night, and Mark was close—close enough that Jin had agreed to wait one more day before the expedition.
Then the world turned red.
It started as a faint shimmer at the edge of Jin's vision, a distortion like heat rising off asphalt. He blinked, thinking his eyes were playing tricks. But the shimmer deepened, intensified, until the entire room was bathed in crimson light.
"What the hell—" Mark's voice came from behind him, cut off as a wave of pressure slammed into Jin's chest.
His knees buckled. The Crimson Book mark on his left hand blazed, the faded black lines flaring back to life with searing heat. Jin gasped, clutching his hand as the pain shot up his arm. Beside him, Mark and Lisa had gone pale, their marks glowing through their sleeves. Simon stood rigid, veins standing out on his neck, his face a mask of agony.
Through the window, the fog was changing. Tendrils of gray twisted and writhed as if caught in a storm, and somewhere in the distance—above, beyond, everywhere—a sound like a heartbeat thundered through the sky. Once. Twice. Three times.
Jin's mind flashed back to the first night, to the Eye in the sky, to the red light that had transformed so many into monsters. This was the same. And different. The pressure was not trying to crush him; it was flowing through him, filling something he hadn't known was empty.
The mark on his hand pulsed in rhythm with the heartbeat. The Crimson Book appeared unbidden in his mind, its pages flipping on their own, settling on Fidex's page. New lines of text were forming, burning themselves into the paper in letters of molten gold.
Then, as suddenly as it began, the light faded. The pressure lifted. The heartbeat receded into silence.
Jin slumped against the window frame, gasping. His hand throbbed where the mark had flared, but the pain was already dulling. He looked at his palm. The Crimson Book symbol was different now—more intricate, the lines branching like veins, the red deeper than before.
Across the room, Mark was on his knees, breathing hard. Lisa had her hands pressed against the wall, steadying herself. Simon stood with his fists clenched, staring at his own hand.
"Is everyone okay?" Jin asked, his voice rough.
"I think so," Mark said. He flexed his fingers, wincing. "What the hell was that? Another wave?"
"Not like the first one," Lisa said. Her voice was shaky, but her eyes were sharp. "I didn't feel like I was going to turn. It was more like… like something opened up. Inside."
Jin nodded slowly. He felt it too. A new channel, a deeper connection to the Crimson Book. To Fidex. And something else—a sense that his own power had changed, expanded. The Fusion ability that had been limited to his Summon now pulsed with new potential, waiting to be tested.
He turned to the others. "Check your Summons. See if anything's changed."
Mark summoned his creature—a humanoid corpse, lean and fast, that had been First Order Low until yesterday. Now it stood taller, its movements smoother, its eyes burning with a new intelligence. Mark stared at it, then at his hand.
"It's not just the Summon," he said slowly. "I can feel… something. Like I know where it's going to move before it moves. Like we're connected in a way we weren't before."
Lisa had already summoned her Mutant Rat. The creature sat at her feet, its crimson eyes fixed on her. She was looking at it with an expression of wonder—and something else. Her gaze went distant, unfocused.
"I can see through it," she whispered.
Jin watched as her eyes tracked something he couldn't see. The Rat's head turned, its gaze moving in perfect sync with Lisa's unfocused stare.
"There's someone in the hallway," she said. "It's Nathan. He's checking doors. He looks scared."
Her eyes snapped back into focus, and she blinked rapidly. "That's… that's new."
"A shared perception," Jin said. He filed it away. The surge had awakened new abilities in them—abilities beyond the simple Contract. What else had it done?
Simon had been silent throughout. He was looking at his hands, turning them over, flexing his fingers. There was a tension in his shoulders, a coiled readiness that hadn't been there before.
"Simon?" Jin prompted.
"I don't know," Simon said slowly. "I don't feel anything new. But when I summoned my Corpse—" He gestured, and the creature materialized beside him. "I felt something. Like a weight settling into my bones. Like I could take a hit and keep going."
He looked at Jin. "I've been in fights before. When I was younger, before my son was born. There was always a point where the adrenaline ran out, where the body started to fail. Now…" He trailed off, frowning. "Now I feel like the longer it goes, the stronger I get. The harder I am to put down."
Jin considered this. A stamina skill, perhaps—the opposite of what most people would experience. The longer Simon fought, the more his body adapted, the more damage he could absorb. It fit the man who had chained his own son in a room rather than kill him, who had endured days of waiting without breaking.
The surge had given them what they needed. What they had earned.
Jin looked out the window again. The fog was still there, pressing against the glass, but it seemed thinner now, less oppressive. Or maybe that was just his perception. The red light was gone, but something had changed. The world had shifted again, and they had shifted with it.
"What about you?" Mark asked. "Your Summon—did it change?"
Jin called Fidex. The Four-Armed Corpse materialized in the center of the room, its metallic skin gleaming dully in the dim light. At first glance, nothing seemed different. But when Jin reached out through the Contract, he felt it: the Fusion system had expanded.
Before, he could only fuse materials into Fidex. Now, there was a new branch—a new possibility. He could feel the potential to fuse materials into himself. Not through the Summon, not as a synchronized skill, but directly. The Crimson Book had offered him a choice, a new path.
He didn't know what it meant yet. What the limits were. What the cost might be.
But he intended to find out.
"It changed," Jin said simply. He dismissed Fidex and turned to the others. "We all changed. The surge hit everyone—everyone who survived. That means the other survivors in the building might have awakened abilities too. And the Contractors out there, the ones we don't know about."
Mark's expression tightened. "That could be a problem. If someone got something dangerous, if they decide they don't want to follow your lead—"
"Then we deal with it," Jin said. "Same as we've dealt with everything else." He looked at the Brilliance Tree, still glowing softly on the desk. "But first, we need water. We need supplies. The surge doesn't change that."
He crossed to the map, still spread across the desk, and studied it for a long moment.
"We go tomorrow. Dawn. Mark, you work on controlling that new connection to your Summon. Lisa, practice seeing through your Rat's eyes—if we're out in the fog, that kind of scouting will save our lives. Simon, test your limits. See how much punishment you can take before you start to slow."
Simon nodded, a grim determination settling over his features.
"And me?" Mark asked.
"You and your Summon need to move as one unit. If you know where it's going to strike before it strikes, you can coordinate better. Use that."
Jin looked at each of them in turn. "We're not the same people we were two hours ago. None of us are. But that doesn't mean we stop moving forward. Tomorrow, we go outside. We find water. We find supplies. And we figure out exactly what this new world has made us."
He let the words hang in the air. Outside, the fog pressed against the windows, patient and waiting. But for the first time since the cataclysm, Jin felt like the waiting was almost over.
The surge had come. The world had changed again.
And he was ready to change with it.
