The Bone Sentinel took a step forward, its movements silent and fluid, and the temperature in the cavern plummeted. A hoarfrost instantly crystallized on the phosphorescent moss, dimming the eerie light. This was not the brute force of the Titan or the skittering hunger of the Jackals. This was a cold, focused purpose. The air itself felt heavy with its intent to preserve the sanctity of the tomb.
Leo felt a new sensation-not fear, but a spark of intense curiosity. This thing was different.
The Sentinel didn't charge. It simply swung its rib-scythe in a wide, horizontal arc. No wind was generated; instead, a visible wave of absolute cold shot forth, a shimmering crescent of energy that flash-froze the very air in its path, leaving a trail of glittering ice crystals. It wasn't aiming to cut him, but to encase him in a prison of eternal ice.
[Incoming cryogenic energy. Composition: Advanced Magical. Threat Level: High.]
The wave of cold hit Leo.
Instantly, his forward momentum halted. His gelatinous form stiffened, the vibrant jade-green darkening to a murky, opaque teal as every molecule of his body was seized by the magical deep-freeze. With a sound like shattering glass, he was transformed into a solid, frozen statue, his pseudopod still outstretched towards the giant skeleton. The ice that encased him was not clear, but a swirling, magical blue, pulsing with the Sentinel's power.
For a single, perfect second, he was trapped.
Then, deep within the frozen core of his being, the Principle of Adaptive Immortality engaged. It was not a conscious thought, but a fundamental law reasserting itself. The magical energy that comprised the "concept of freezing him" was analyzed, processed, and then... adopted. It was filed away as an "ineffective state."
The ice did not melt. It shattered from the inside out.
A web of cracks appeared across the frozen block, glowing with the same intense jade light of Leo's core. With a deafening CRACK, the magical ice exploded outward, sending shards like daggers ricocheting around the cavern. Leo stood completely unfrozen, his body once again fluid and vibrant, the mineral flecks within him swirling faster, as if agitated.
The Bone Sentinel paused, its featureless head tilting. The two pinpricks of blue light flickered. Its primary method of containment had failed. Utterly.
It adapted. It raised its free hand, and the petrified roots that comprised its arm writhed, elongating like spears. They shot across the cavern, not aiming to pierce, but to ensnare, wrapping around Leo's limbs and torso with the speed of striking serpents. They began to constrict, applying immense pressure meant to pulverize stone.
The roots tightened... and then slackened. They lost their rigidity, becoming soft and pliable. The life and magic within them were being siphoned out, turning them into lifeless, dry vines that crumbled to dust around him. Leo stood, having passively absorbed the energy that gave the roots their strength.
[Host has absorbed [Ancient Guardian Essence]. Magical resistance parameters have increased.]
The Sentinel recoiled, the roots that were part of its own body now dead. It understood now. Physical force, elemental magic, binding nothing was working. The blue lights in its eyes flared with a final, desperate intensity. It planted its feet, and the entire cavern began to hum. The phosphorescent moss on the walls blazed, and all the light was drawn into the Sentinel, concentrating into a sphere of blinding white energy between its hands a final, self-destructive blast fueled by its own core and the latent magic of the tomb.
It was going to annihilate itself and the intruder in one cataclysmic purge.
The sphere grew, pulsating with destructive power.
Leo didn't wait for it to fire. The instinct to siphon was now as natural as breathing. He didn't just pull a little; he reached out with his will and performed a full, targeted Energy Siphon on the core of the spell itself.
The growing sphere of light stuttered. Instead of expanding, it began to shrink, streams of pure, white energy tearing away from it and flowing into Leo. The Sentinel shuddered violently, the blue lights in its eyes dimming. It was trying to give its life for its duty, and he was taking that final sacrifice away from it. The sphere collapsed in on itself with a pathetic fizzle, and the Bone Sentinel, its purpose and power utterly drained, crumbled. Its polished bones lost their luster, clattering to the stone floor in a lifeless heap, and the petrified roots turned to gray ash.
Silence returned to the cavern, deeper than before.
Leo felt the new energy settle within him. It was clean, old, and potent. He felt more real, more substantial, his magical defenses now layered with the ancient power of the guardian.
He looked from the pile of bones that was the Sentinel to the colossal, obsidian skeleton it had died to protect.
[It was guarding this,] he thought, the simple logic of it clear.
[Affirmative. The guardian's existence was tied to the remains. Its purpose was to prevent unauthorized contact.]
Leo turned his attention back to the giant black rib he had been touching. The concept of Flight was now a part of him, a dormant understanding. He placed his pseudopod on the bone again, but this time, he pushed. Not with physical force, but with his will, his Terrakinesis.
The obsidian bone, harder than any diamond, resisted for a moment, then, with a deep groaning sound, it cracked at its base. With a final, grating snap, the colossal rib broke free. It was over twenty feet long and impossibly heavy.
Leo focused. He wouldn't carry it; he would command it. Using his Terrakinesis, he lifted the giant rib, willing it to reshape. The obsidian bone groaned and compressed, its structure condensing, its length shortening, its form smoothing and sharpening. In moments, the twenty-foot rib was transformed. It was now a six-foot-long staff, as black as a starless night, perfectly smooth, and impossibly hard. It was both a focus for his power and a formidable weapon.
He held the staff, forged from the bone of a forgotten leviathan. He had the compass that led to secrets. And he had a new, sky-born concept sleeping within him.
The tomb had given him its gifts. It was time to return to the world above, to see what other mysteries the Dark Forest and the compass's next direction would reveal.
