The steep descent finally began to level out. The tunnel widened gradually, the bone floor becoming smoother and more deliberate in its curve. The marrow currents flowed with greater purpose now, no longer lazy rivers but directed streams that converged toward a single distant point. The warmth had grown intense, bordering on oppressive, yet it carried a strange vitality that made each breath feel heavier and more alive. The titan's heartbeat no longer echoed from every direction. It came from directly ahead, deep and resonant, like the slow drum of an enormous heart waking from centuries of sleep.
Jidd slowed his pace as the passage opened into what felt like the threshold of something significant. The walls here were etched with denser lattice patterns, glowing faintly with intertwined green and indigo threads. The air tasted of concentrated marrow and ancient stone, thick enough to coat the tongue.
"We are close," he said quietly, stopping at the edge of the widening space. "The pulse is different. Stronger. More focused."
Inkwell tightened his grip on Jidd's shoulder, all remaining tentacles alert. "Finally. I was starting to think we would walk until the end of time itself. My suckers are numb from all this marching. If the next room does not have at least a puddle of something caffeinated, I am staging a mutiny."
Venn moved up beside them, her device humming as it processed the sudden increase in lattice density. Blue scans swept forward, revealing layered readings that made her brow furrow. "The core consciousness layer is just ahead. We have passed the transitional zones. This is the outer perimeter of the titan's primary neural matrix. The barriers are under more strain here, but they are still holding. The synchronization is almost complete. Jidd, your resonance is matching the titan's pulse almost perfectly now."
Jidd felt it. Not as an overwhelming pull, but as a deep, steady alignment. The heartbeat matched his own so closely that distinguishing between them grew difficult for brief moments. He did not fight it. He simply noted it, the boy's caution keeping him grounded while the deeper part observed without claiming ownership.
The passage ended at a natural archway formed from two massive fused ribs. Beyond it lay a chamber unlike any they had seen. The space was immense yet intimate, a spherical cavern with walls that curved inward like the inside of a colossal ribcage sphere. At the center hovered a single enormous vertebra, suspended by thick marrow strands that pulsed with living light. This was not the throne-like structure from earlier. This felt like the heart of the heart, the titan's core consciousness made visible in bone and energy.
Faint indigo light radiated from the central vertebra, casting long shadows that shifted with every beat. No immediate echoes disturbed the air. The chamber felt held in suspension, as though the titan itself had paused to regard the small group that had journeyed so far.
Jidd stepped through the archway first. The moment his foot crossed the threshold, the heartbeat deepened noticeably. A single, powerful thump rolled through the chamber, vibrating through his bones and making the marrow strands tremble. He stopped in the center of the open space, looking up at the suspended vertebra.
"It knows we are here," he said, voice calm but carrying new weight. "Not attacking. Just... aware."
Inkwell let out a low, bubbling whistle. "Aware is putting it mildly. That thing is staring at us with its entire being. I can feel it in what is left of my stumps. Kid, if you are going to have a meaningful conversation with your long-lost sibling, now would be the time to set some ground rules. Like 'no devouring the octopus'."
Venn positioned herself to Jidd's left, device raised and scanning the central structure frantically. "The lattice here is the strongest we have encountered. This is the indexing nexus for the entire titan. If I can interface properly, I can reinforce the barriers one final time before any direct contact occurs. But we have to be fast. The core is responding to your presence. It is not hostile yet, but it is curious."
She moved toward one of the marrow strands anchoring the central vertebra and began attaching her device. Blue energy flowed into the strand, syncing with the indigo light. The central structure pulsed once in response, brighter than before.
Jidd stood motionless, watching. The alignment inside him held steady. No sudden ego surges. No overwhelming hunger or visions. Just the quiet recognition that he had reached a place where choices would matter more than they had at any point since waking. The boy who had screamed in the colony felt the weight of that responsibility. The fragment inside simply waited, patient and ancient.
The heartbeat thumped again, slower and deeper. This time it carried a faint undercurrent that brushed against the edges of Jidd's barriers. Not words. Not commands. Simply presence. Recognition between pieces of the same broken whole.
Inkwell shifted uneasily. "That felt personal. Like it just said hello in god-language. Jidd, you still with us?"
"I am here," Jidd replied, his voice steady. "Both parts of me. It is not pulling. Not yet. It is just... looking."
Venn worked faster, her fingers dancing over the controls. "I am establishing a stronger dampening field. It should buy us a few more minutes of clarity. Do not reach out yet, Jidd. Let me finish the interface first. We need every advantage before the core fully engages."
The central vertebra pulsed again, the indigo light brightening around its edges. The marrow strands holding it trembled slightly, as if the titan was adjusting its posture to better regard the small fragment that had walked so far into its depths.
Jidd stood in the center of the chamber, flanked by his companions, and waited.
The long walk through the Depths had ended.
Now the real conversation was about to begin.
