The heavy groan of the ancient bulkhead grinding shut behind them was swallowed instantly by the oppressive silence of the maintenance tunnel. It was a different kind of silence than the sterile quiet of the Weaver's Creche – thicker, damper, laden with the dust of ages and the scent of decay. Rhys stumbled, leaning heavily on Boulder's steady arm, the abrupt transition adding to the profound sense of dislocation washing over him. The adrenaline that had carried him through the encounter with the Guardian and the desperate activation of the nexus crystal was rapidly fading, leaving behind a bone-deep exhaustion unlike anything he'd ever felt.
His Aether Pool wasn't just low; it felt scoured clean, scraped down to the very bedrock of his being. The consequences were immediate and debilitating. His Echo Sense, usually a vibrant tapestry of energy signatures guiding him through the darkness, was now frustratingly muted, like trying to see through thick fog. He could perceive only the immediate vicinity – the cold dampness of the rough-hewn rock walls, the faint metallic tang of corroded pipes running along the ceiling, Boulder's solid, worried presence beside him. Beyond a few yards, the world dissolved into indistinct energetic static. He felt blind, vulnerable, stripped of his most crucial tool for navigating the treacherous depths.
Physical weakness followed close behind the sensory deprivation. Nausea churned in his stomach, his head throbbed with a dull, persistent ache, and his limbs felt leaden, unresponsive. Pouring his essence into the Weaver nexus hadn't just drained his Aether; it had leeched his physical vitality as well. Every step was an effort of will.
"Easy, Rhys," Boulder murmured, his voice a low rumble that was oddly comforting in the suffocating dark. He adjusted his grip, taking more of Rhys's weight. "Just keep moving. Slow."
They pressed onward into the cramped, unknown passage. Deprived of his Echo Sense for long-range navigation, Rhys relied on logic and observation. The tunnel seemed to slope gradually downwards, twisting and turning unpredictably. Pipes lined the walls, some intact, others ruptured and leaking foul-smelling slime. The air grew thick with dust disturbed by their passage, making each breath a gritty irritation.
Progress was agonizingly slow. Several times, they encountered obstacles that would have been easily anticipated with functioning Echo Sense. A section of the tunnel floor abruptly gave way to crumbling brickwork, forcing them to backtrack and find a narrow, precarious ledge to bypass it. Further on, sparks spat intermittently from a damaged electrical conduit recessed in the wall, the crackling discharge filling the narrow space with the sharp smell of ozone. Rhys felt the hazardous energy signature only when they were dangerously close, forcing a hasty retreat and another detour down a side passage choked with debris.
The atmosphere itself was oppressive. The silence was broken only by the echo of their own footsteps, the drip of unseen water, and the occasional groan of stressed rock or metal settling somewhere in the unseen depths. It felt ancient, neglected, a forgotten artery in Meridian's deepest foundations. Once, a section of the ceiling directly above them shifted with a terrifying grinding sound, showering them with dust and small pebbles. They scrambled back, hearts pounding, waiting for a collapse that thankfully never came, but the incident underscored the inherent instability of these old tunnels.
Rhys knew he couldn't keep going like this. His vision was blurring at the edges, the nausea intensifying. Pushing himself further in this depleted state risked collapse, or worse, stumbling blindly into a hazard his dulled senses couldn't detect. "Need… to stop," he gasped, leaning heavily against a damp, cold wall. "Just… for a bit."
Boulder scanned their immediate surroundings, his eyes piercing the gloom. He spotted a narrow opening partially obscured by fallen masonry – a side chamber, perhaps an old access point or forgotten storage alcove. After checking it cautiously for immediate threats, he helped Rhys inside. It was small, barely large enough for both of them, but blessedly dry and offered a single, defensible entrance. Boulder used loose rocks and debris to crudely barricade the opening, creating a fragile illusion of security.
Inside the cramped space, Rhys slumped against the wall, utterly spent. He checked his forearm where the Guardian's acid had grazed him. The skin was red and blistered, intensely painful, but Kaelen's pungent salve seemed to have neutralized the worst of the corrosion, preventing it from eating deeper. Boulder, stoic as ever, examined the smoking patches on his own leathers, grimacing slightly as he applied a smear of the salve to a burn that had reached his skin underneath.
Their supplies were practically non-existent. The last smear of nutrient paste was long gone. The fungi they'd gathered in the Weaver ruin felt like a distant memory. Their waterskins held perhaps half a day's ration if they were careful. Resting was essential, but starvation and dehydration were rapidly becoming immediate threats.
Seeking some small measure of progress, Rhys pulled the Weaver datapad slate from his satchel. Its surface was cool and smooth in the darkness, the faint internal hum a subtle vibration against his palm. He tried to focus his will, channeling the absolute dregs of his remaining Aether towards it. It was like trying to strike flint with wet straw. The slate remained inert, its intricate surface patterns dark and unresponsive. He lacked the energy, the focus, the sheer capacity to interact with it in his current state. Frustrated, he carefully wrapped it in a spare piece of cloth and secured it back in his satchel. It was a potential key, but useless without the strength to turn it.
As profound exhaustion began to pull him under, blurring the edges of the cramped alcove, Rhys caught it – a faint, intermittent sound filtering through the thick rock walls. Not the random groans of the ruin settling, but something more rhythmic. A distant scrape… drag… scrape… like something heavy being moved across stone, far away but persistent. Was it just geological stress? Or was something else moving down here in the deepest dark, something stirred by their passage or the Guardian's rage? The thought sent a fresh wave of unease through his depleted system. They had escaped the immediate danger, but the depths held their own secrets, and their vulnerability felt absolute. Recovering his Aether wasn't just necessary for escape; it was critical for basic survival, for simply knowing what shared the darkness with them.
