The Ironbark fibers snapped with a clean, surgical pop. Kael tumbled off the metal table, his legs feeling like they were made of cooling wax.
"Don't just lie there, Specimen," Elara hissed, her shadow stretching long against the wall as she moved toward the back of the clinic. She wasn't looking for a weapon; she was frantically pulling a series of hidden levers concealed behind a shelf of bubbling gene-sequencers.
Downstairs, the sound of the clinic's front desk being splintered under armored boots was accompanied by a shout. "Check the storage! If the doctor keeps her mouth shut, break her fingers until she remembers!"
"This way," Elara commanded.
A section of the tiled wall groaned and slid aside, revealing a pitch-black chute that smelled of damp moss and industrial grease. These weren't standard drainage pipes; they were the smuggling tunnels of the undercity, a labyrinth used by gene-black-marketers and "Pruners" like Elara to evade the Guild's tax-collectors and enforcers.
"Move!" Elara shoved Kael toward the opening just as a beam of red sensor-light cut across the threshold of the surgery room.
Kael didn't need further encouragement. He dove.
The slide was a vertical nightmare of friction and cold metal. He hit a level floor seconds later, his shoulder—the one grazed by the panther earlier—erupting in a fresh wave of agony. Elara landed gracefully beside him, already lighting a chem-stick that bathed the narrow stone corridor in a flickering, sickly violet light.
"Keep your head down," she whispered, her voice tight. "These tunnels aren't structurally sound. If they use explosives upstairs, the whole sector could drop on us."
They ran. Every step was a battle for Kael. The "System" in his mind was no longer a helpful guide; it was a frantic metronome of warnings.

"I... I can't keep up," Kael gasped, his lungs feeling like they were being scraped by a file.
"You will keep up, or you will be a very expensive corpse for Jax to find," Elara shot back, though she slowed her pace just enough to keep him within the chem-stick's light.
They reached a heavy, iron-bound hatch—the exit to the deeper sewers. But as Elara pulled the latch, it didn't budge. The mechanism was fused, not by age, but by a thick, calcified expansion of Root-Rot that had grown over the hinges.
"Dammit," Elara snarled, kicking the door. "The humidity... it's triggered a growth spurt in the fungus. We're trapped."
The sound of rhythmic thudding echoed from the tunnel they had just left. The Ironbark weren't sliding down the chutes; they were cutting their way through the floor.
"Kael," Elara turned to him, her eyes wide and desperate in the violet light. "The acid. Use it on the hinges."
"I... I used it all," Kael croaked, leaning against the damp wall. "The system... it says I'm empty."

"Do it!" Elara gripped his shoulders, her voice a sharp command. "If we don't get through this door, we're both dead. Draw from whatever you have left!"
Kael looked at the hatch, then at the flickering light. He felt the cold, parasitic hunger of the Orchard reaching deep into his bones, looking for something to burn.
He didn't spit a jet. He didn't have the pressure. He simply unhinged his jaw and let the remaining, concentrated bile—now a dark, caustic sludge—leak from his throat directly onto the calcified fungus.
The hiss was terrifying. A thick, yellow smoke filled the tunnel, smelling of burnt bone. The Root-Rot dissolved, shrieking with a sound that Kael felt in his own teeth.
But as the hinges finally gave way and Elara wrenched the hatch open, Kael felt the world fracture.

"Ah—!"
His words dissolved into a choked gargle. Kael's body didn't just collapse; it locked. Every muscle in his frame went rigid, his back arching until he felt his spine groan. His needle-fingers erupted from his skin, spasming uncontrollably as they tore at his own clothes.
The violet light of the chem-stick began to strobe in his vision, each pulse accompanied by a jolt of raw electrical fire through his brain.
"Kael!"
Elara's voice was distant, muffled by a rushing sound like a waterfall in his ears.
His eyes rolled back, and the last thing he saw was the emerald light in his chest flickering, fading, as the first wave of the seizure took him.
