The crack in the cave wall was barely wider than my core. I rolled deeper, feeling the rough stone scrape against my crystal surface. Each rotation sent tiny vibrations through my awareness—the echo of dripping water somewhere ahead, the distant scuttling of cave insects, and behind me, the fading shouts of goblins.
I stopped rolling. Listened.
The shaman's voice was a sharp, guttural chant. The other goblins answered with grunts. They were still searching the treasure pile, still arguing about the flying dagger. But they had not followed me into the tunnel. Not yet.
I continued rolling.
The tunnel sloped downward. The air grew damp and cold. My energy was low—only 5 out of 150 after the level up. I needed mana. I needed to absorb.
A system window appeared in my mind.
Current status: Metamorphosis Core (Level 3)
Energy: 5/150
Ambient mana absorption: 0.5% per hour
Transformations available: Pebble (10), Acorn (10), Dewdrop (5), Thorn (15), Small Stone (10)
Note: Low energy. Transformation not recommended.
I could not stay as a core forever. Without energy, I could not transform, and without transformation, I could not defend myself or escape. I needed to find a mana source.
The tunnel opened into a small chamber. The ceiling was low, covered in glowing moss. The moss emitted a faint, greenish light. I extended my awareness. The moss was alive—weak, but alive. And it contained mana.
Mana source detected: Glow Moss. Absorption rate: 2 energy per minute.
I rolled toward a patch of moss and pressed my core against it. A tingling sensation spread through my crystal. The moss dimmed slightly as I absorbed.
Energy: 10... 15... 20...
The system updated.
Energy: 25/150. Sufficient for basic transformations.
I stopped absorbing. The moss was now a dull grey. I had taken too much. But I did not care. Survival first.
I heard a noise. Not goblins. Something heavier. Something that dragged its feet and breathed in long, wet rasps.
I rolled into a crevice between two rocks and went still.
A shape emerged from the tunnel behind me. It was not a goblin. It was a troglodyte—a pale, eyeless humanoid with a wide mouth full of needle teeth. Its skin was slick with moisture. It crawled on all fours, sniffing the air with a flat, twitching nose.
The creature stopped near the patch of dead moss. It tilted its head. Then it turned and stared directly at my crevice.
It cannot see me, I thought. It has no eyes. But it can sense vibrations.
I held absolutely still. I did not even allow my core to pulse with mana. The troglodyte crept closer. Its breath smelled of rotting meat. The stench was so thick I could almost taste it—a mixture of old blood and damp fur. My core wanted to shudder, but I forced stillness.
One step. Two.
Its hand brushed against the rock that hid me. The rock shifted. I felt the creature's rough, calloused skin against my core. The texture was like sandpaper coated in slime.
If it picks me up, I am dead.
The troglodyte snorted. A puff of warm, foul air washed over me. Then it turned and crawled away, disappearing into a side tunnel. The sound of its dragging footsteps faded, replaced by the drip of water from the ceiling.
I waited. Counted to one hundred in my head. Then I rolled out of the crevice and continued downward.
The tunnel widened. The air grew warmer. And ahead, I saw a faint blue glow.
I rolled toward it.
The chamber was enormous. Stalactites hung from the ceiling like stone teeth, each one dripping with slow, patient water. The floor was covered in broken rock and dried bones. Some of the bones were small—rodents, perhaps—but others were larger, thicker, with scratch marks that spoke of violent ends. And everywhere, embedded in the walls and floor, were mana crystals. Some were as small as my core. Others were the size of my fist. One, in the center of the chamber, was as large as a human head.
The ambient mana was thick. I could taste it—a metallic sweetness that made my core hum like a tuning fork. The air itself felt heavy, almost syrupy.
High-density mana sources detected. Absorbing...
Energy: 30... 40... 50...
I rolled to the nearest small crystal and pressed myself against it. The absorption was fast. Too fast. My core began to vibrate, and a high-pitched ringing filled my awareness.
Energy: 100/150. Warning: Overabsorption may cause instability. Recommend stopping at 120.
I pulled away. Energy settled at 115. I felt full. Stronger. My awareness expanded—I could now sense the entire chamber, every crystal, every bone, every crack in the wall. I could even feel the faint heartbeat of a small bat hanging from the ceiling.
A system message appeared.
New transformation available: Thorn. Cost: 15 energy. Duration: 20 minutes.
Description: A sharp, woody spine. Currently non‑toxic. To gain poison, absorb a venomous creature.
I read the note. Absorb a venomous creature. That meant I needed to find something deadly and consume it. The idea made my core shiver, but I had no choice. A plain thorn was nearly useless.
I practiced transforming. Pebble. Small stone. Acorn. Each form lasted a few seconds before I reverted. I learned how they moved, how they felt. A pebble rolled smoothly. A stone bounced erratically. An acorn was lighter, easier to carry, but it also made a faint clicking sound on the stone floor.
Then I heard a skittering sound.
I turned my awareness toward a pile of bones near the far wall. Something was moving among them. Small. Fast. Many legs.
A cave centipede emerged from the bones. It was as long as my forearm, its body segmented and dark brown, each segment lined with tiny hairs that caught the blue light. Two curved fangs dripped with a clear liquid. It scuttled toward me, its antennae twitching, tasting the air.
I rolled backward, but the centipede was faster. It lunged.
Its fangs struck my core. I felt a sharp sting—not physical, but energetic, like a needle of ice piercing my consciousness. The centipede's venom entered my crystal. My energy dropped by 10 points.
I panicked. I transformed into a small stone and crushed the centipede against the floor. The stone was heavy enough to pin its head. The centipede thrashed, its legs scratching the rock, leaving faint white scars on the stone. A disgusting crunch echoed through the chamber.
A system window appeared.
Venomous creature neutralized. Absorb its essence? (Y/N)
Warning: Absorption will grant your thorn transformation a mild paralytic poison. Duration: 1 hour per use. Cost: 5 energy per application.
I selected Yes.
The centipede's body dissolved into a green mist that seeped into my core. I felt a new sensation—a cold, tingling energy stored in a separate compartment, like a small vial of liquid ice. The system updated.
Thorn transformation upgraded. Poison effect: Causes local numbness and mild paralysis for 5 minutes. Not lethal. Effective against small to medium creatures.
I examined the new thorn. It was still small, still fragile. But now it carried a weapon. One prick could slow down a goblin, maybe even a shaman. I imagined the shaman's leg going numb, his chant faltering. The thought gave me a grim satisfaction.
I continued practicing. I transformed into the thorn and practiced sticking it into a crack in the wall. The poison activated automatically when I pierced flesh. I withdrew the thorn and reverted. Each transformation cost a little energy, but I had enough for now.
Then I heard voices.
The goblin shaman. He had entered the tunnel above. His crystal glowed, casting a pulsing light on the walls. Two larger goblins followed him, carrying torches and crude spears. The torchlight flickered, casting dancing shadows on the stalactites.
The shaman pointed at the floor. He had seen my trail—the scrapes where my core had rolled over dust, the tiny grooves left by my transformations.
He is tracking me, I thought. His crystal can sense my energy.
I needed to hide. But the chamber had few crevices. The crystals were too large to hide behind. The bones were scattered.
I transformed into a small stone and rolled into a pile of rubble near the wall. The stone was grey, rough, indistinguishable from the other rocks. I held perfectly still.
The goblins entered the chamber. The shaman raised his crystal and swept it across the room. The light passed over me.
The crystal flickered.
The shaman frowned. He turned and swept again. The crystal flickered again, brighter this time.
He knows I am here, I thought. But he does not know exactly where.
The shaman spoke to his guards. Their language was guttural, full of harsh consonants. They spread out, poking their spears into the rubble.
One guard approached my pile. His spear tip scraped the rocks. He was three feet away. Two feet. One.
I had to act.
I transformed into my core form—a marble-sized crystal—and rolled behind a larger rock. The guard heard the noise. He turned and thrust his spear into the spot where I had been.
The spear struck the rock. Sparks flew. The guard grunted in surprise.
I transformed into the thorn.
The thorn was small, black, and tipped with a greenish sheen. I could feel the poison reservoir in its tip, cold and ready. I pushed myself against the ground and launched toward the guard's calf.
The thorn embedded itself in his leg just below the knee.
The guard screamed. He dropped his spear and grabbed his leg. The poison worked quickly. His calf went numb, then his knee. He stumbled, then fell to the ground, clutching his leg and howling. The other guard ran to help him, but slipped on the wet stone and nearly fell.
The shaman shouted. He raised his crystal and chanted. A wave of red light swept across the chamber.
I reverted to my core form and rolled toward the far wall. The red light passed over me. I felt a jolt of pain—like a static shock that rattled my very being—but I kept rolling.
The shaman was pointing at me. He had seen my core.
I transformed into a dewdrop—a small, glistening sphere of water—and merged with a puddle on the floor. The puddle was shallow, but it was enough. The shaman's red light swept over the puddle and passed on.
He could not distinguish me from the water.
The goblins searched the chamber for another minute, then regrouped near the shaman. The poisoned guard was still on the ground, his leg useless, his face pale. The other guard was arguing, pointing at the tunnel entrance, clearly wanting to leave.
The shaman looked frustrated. He kicked a rock, then led his guards back up the tunnel, dragging the injured one. Their voices faded.
I waited. Counted to two hundred. Then I separated from the puddle and rolled toward a narrow crack at the back of the chamber. The crack led to a smaller tunnel. I followed it.
The tunnel ended at an underground river.
The water was black, cold, and fast. It emerged from a hole in the wall and disappeared into another hole fifty feet away. The sound of rushing water filled the space, a constant roar that made my core vibrate. The air smelled of wet stone and something else—a faint, sweet odor, like rotting fruit mixed with minerals.
I transformed into a dewdrop again and let myself fall into the river.
The current grabbed me. I tumbled, spun, and merged with the water. I could not see—only sense the pressure and the cold. The river carried me through darkness. Small blind fish brushed against me, their scales smooth and cold. I absorbed a tiny amount of mana from them, but not enough to matter. The current was relentless, pulling me downward.
Minutes passed. Maybe hours. I lost track of time. The only constant was the roar of water and the occasional bump against a submerged rock.
Then the river slowed. The tunnel widened. I felt a faint blue light ahead.
The river deposited me into a large cavern.
The light came from a massive crystal embedded in the ceiling. It pulsed like a heartbeat, casting slow blue shadows across the walls. The crystal was easily the size of a wagon wheel, and its glow illuminated every corner of the cavern. Below it, on a stone throne, sat a golem.
The golem was made of dark iron, but it was damaged. Its left arm hung at a wrong angle, the elbow joint rusted and cracked. Two fingers on its right hand were missing. A deep gash ran across its chest, just above a hollow cavity shaped like a sphere. The cavity was empty. Missing a core.
I rolled closer, my core vibrating with curiosity. The golem was massive—three times my height, broad shouldered, its blank face staring at the ceiling. Despite the damage, it looked powerful. A body. A real body that could walk, fight, and speak. I imagined myself inside it, my core nestled in that hollow cavity, controlling iron limbs.
A system window appeared.
Compatible vessel detected: Iron Golem (damaged, dormant).
Possession cost: 3500 energy.
Current energy: 45.
Warning: Golem is heavily damaged. Possession success rate: 30%. Failure may result in core fragmentation.
Note: This golem is an ancient construct from the Clockwork Dominion, a mechanical city far to the east. If repaired, it could serve as a permanent vessel and a means of travel.
I read the words twice. Clockwork Dominion. Mechanical city. A city of machines, far from these damp caves. A place where I could walk among beings like this golem. A place where I would not be a helpless crystal hunted by goblins and troglodytes. I could almost see it in my mind: towers of brass and steel, streets lit by glowing crystals, beings of metal and magic living in harmony.
But 3500 energy. I had 45. The gap was enormous. It would take weeks, maybe months, of absorbing mana from weak sources like glow moss and small crystals. I would need to find richer sources, perhaps even defeat stronger creatures to drain their essence.
I looked at the golem's missing fingers, its cracked joints, the gash on its chest. Even if I somehow gathered 3500 energy, the possession might fail. My core could shatter. I would become nothing. No second chance. No void. Just an end.
The river carried me toward a rocky bank. I rolled onto the stones and reverted to my core form.
I needed to grow. I needed to absorb mana from richer sources than glow moss and small crystals. I needed to leave this cave, explore the world above, and find places where energy flowed like water. Maybe forests with ancient trees. Maybe dungeons filled with monsters. Maybe even that mechanical city itself.
And then, maybe, I would return to this cavern. I would repair the golem, piece by piece. I would gather 3500 energy. I would risk the 30% chance.
Because that golem was my ticket out of here. My first real chance at freedom. Not just freedom from goblins, but freedom from this fragile, rolling existence. A body. A future.
But first, I had to survive the night.
A cold draft blew through a crack in the cavern wall. It carried the smell of damp earth and something else—something metallic, like oil and heated iron. The mechanical city. Even here, deep underground, I could sense it, distant but real. A promise.
I rolled toward the crack. It was narrow, barely wide enough for my core. Beyond it, I felt open space. A tunnel leading upward. The air was fresher, colder, carrying the faint scent of pine and soil.
I rolled into the darkness.
