The medical tent was a chaotic swirl of crimson alarm light and panicked motionSenshi and Himari pushed through the heavy moss flaps nearly colliding with a healer carrying an armful of glowing fungi In the center of the tent sitting on a wooden cot and clutching his head was TorisToris was young barely older than Senshi He had been Returned for less than three months dying in a scaffolding collapse in the Middle Tiers His physical form still bore the fresh jagged scars of his death and his eyes—a pale watery blue—were wide with uncomprehending terror But it was the light radiating from his skin that drew the eye He was pulsing Not with the steady rhythmic amber of the Root but with a chaotic strobing white light that flared and died in erratic frantic burstsToris Himari barked dropping to her knees beside him She grabbed his wrists trying to steady his trembling hands Look at me Focus on my voice Anchor to the woodI can't stop it Toris gasped his voice overlapping with a strange

The Deep Weave smelled of ancient dust and dried sap a suffocatingly dry contrast to the damp rotting humidity of the lower Cracks It was a hollowed-out chamber inside a fossilized knot of Pillar Three’s Root the wood here long dead and calcified into a substance as hard as ironSenshi sat on a woven mat the blank kelp-parchment map spread across his knees He was tracing the branching web of burn marks Himari had drawn—the fractures in Pillar Seven’s Root His thumb hovered over the spot where he had patched the crack with sealant just days ago It felt like a lifetimeAcross the small chamber Himari was methodically sharpening her bone-knife The rhythmic shhhk-shhhk of the whetstone was the only sound save for the distant muffled groan of the living Root shifting in the thermal currents Mirova sat in the corner her wooden fingers deftly weaving a basket from pale root-hairWe can't just keep running Senshi said His voice broke the silence rough but steadyHimari didn't look up from her

The bark map was heavy in Senshi’s hands, its surface warm and humming with a faint, residual Pulse. The glow-moss lanterns of the Deep Weave cast long, dancing shadows across the intricate, deeply etched lines. Mirova sat beside him, her blind eyes turned toward the parchment, her wooden fingers hovering just millimeters above the surface, reading the topography through the ambient vibrations of the ink. "These are not Council routes," the elder murmured, her voice like dry leaves scraping over stone. "The Council builds their maintenance shafts in straight lines, boring through the deadwood with seismic drills. These paths... they follow the vascular veins. They curve. They breathe. They pre-date the current Root Guard system by centuries. Perhaps by a millennium."Himari stood near the entrance of the chamber, her arms crossed, her mismatched eyes scanning the dark tunnels beyond. "Kaia was an Engineer in the Peak," she said, her tone clipped, analytical. "She had top-tier cleara

The outer vascular tunnels of Pillar Seven’s Root were not built for human navigation. They were biological arteries, curved and ribbed, pulsing with the slow, agonizing heartbeat of a dying god. The air was thick with the smell of oxidized copper and ancient sap, the walls weeping a viscous, golden fluid that coated the floor in a slick, treacherous film. Senshi and Himari moved through the claustrophobic darkness at a dead run, their breath coming in ragged gasps. The bark map was clutched in Senshi’s hand, its surface warm against his palm, guiding them through the labyrinth of the deep cortex. Behind them, the ambient Pulse of the Root suddenly fractured. It wasn't a physical sound. It was a high-pitched, mechanical whine that pierced the organic hum of the wood, vibrating painfully in Senshi’s teeth. "They found the breach," Himari hissed, not breaking her stride. She glanced back over her shoulder, her mismatched eyes scanning the dark tunnel. "The new scanner. It’s cutting

The pursuit had stopped. Senshi didn't know why. One moment, the deep cortex of Pillar Seven’s Root had been alive with the mechanical whine of Pulse-scanners and the heavy thud of magnetic boots. The next, the ambient noise had simply vanished, retreating upward toward the mid-tiers like a tide pulling back from the shore. Himari had been suspicious, her mismatched eyes darting at every shadow, her hand never leaving the hilt of her bone-knife. But as the hours passed and no Guards breached the pith-chambers, a fragile, exhausted relief had settled over them. They were deep now. Deeper than the Underbelly, deeper than the fossilized knots of the Cracks. They were inside the biological heartwood of the Root, in a massive, spherical cavity that Dip called the "Lung." The chamber was breathtaking and terrifying. It was easily a hundred feet across, hollowed out by centuries of necrotic rot. The walls were lined with towering shelves of bioluminescent fungi, casting a soft, pulsing b
