Dark. Wet. Warm in some places, cold in others, and everywhere the faint pressure of stone.

  That was the beginning. Not a moment of awakening so much as a slow gathering. Awareness arriving in pieces, like water collecting in a hollow until the hollow is full and something spills over and becomes a puddle, and the puddle realizes, dimly, that it exists.

  It did not know what it was. It had no frame of reference for what being was. There was sensation: the cool film of moisture on rock, the vibrations traveling through the ground beneath it, the gentle drip of water falling from the ceiling at intervals so regular they might have been counted if it had known what counting was. And there was itself. A boundary. A shape. Something that ended where the rest of the world began.

  It took a while to find the edges.

  The body was soft and yielding. It shifted when it tried to move, deforming and reforming in ways that felt instinctive but disorienting. Like learning to walk, except walking implied legs, and this had none. What it had was mass. A small amount of it, barely enough to fill a cupped palm. Blue. Semi-translucent. And at the center, suspended in the gel-like tissue, a core.

  The core pulsed. Slow and steady, like a heartbeat. With each pulse, it gave off a faint blue-white glow that lit the surrounding tissue from within, turning the body into a soft lantern in the dark of the cave.

  A slime.

  It did not know the word. Did not know words at all. But it knew, in the way that a seed knows which direction is up, that it was alive, and small, and here.

  ***

  Something appeared.

  Not in the cave. In the slime's awareness. A window of information, floating in the space between perception and thought, as if projected onto the inside of its own body.

  The slime regarded this display with the blank incomprehension of a creature encountering text for the first time. The symbols meant nothing. The numbers meant nothing. Even the concept of a name, that empty space at the top where something should have been but wasn't, failed to register as significant.

  Two things filtered through on an instinctive level. Two abilities, nested somewhere in the core, waiting.

  The first was simple. [Absorb]. The slime understood this without being taught, the way lungs understand air. Take in organic matter. Break it down. Convert it to energy. This was how slimes survived. A baseline function shared by every member of the species.

  The second was less clear. [Heal]. Something lived in the core alongside the pulse, a potential that the slime could sense but not define. It was there. It was part of it. What it did, or how to make it do anything at all, remained a mystery.

  The display faded after a while, sinking back into whatever layer of awareness it had come from. The slime did not miss it. There were more immediate things to figure out. Like what was in front of it. And behind it. And whether the faint vibrations traveling through the ground meant something important or nothing at all.

  ***

  The cave was larger than the slime's limited perception could map at first. An underground chamber fed by a system of groundwater channels, with a ceiling high enough that the dripping water fell for a full second before striking stone. The floor was uneven, carpeted in patches of moss and pale fungus. The only light came from clusters of bioluminescent mushrooms growing along the walls, their caps giving off a sickly green glow that made the cave dim rather than dark. Not quite lightless. Not quite lit.

  Other slimes filled the space. Dozens of them. They occupied niches and alcoves and open stretches of floor, their bodies pulsing with their own rhythms, their colors marking them as different types.

  Red ones that smelled of acid and hissed when anything came close, secreting fluid that ate into the rock beneath them. Green ones that divided when they grew large enough, splitting into two smaller copies of themselves with no apparent awareness that the split had occurred. A scattering of brown and near-transparent ones, each occupying its own corner of the ecosystem without acknowledging the others.

  And near the cave's entrance, taking up a space several times larger than anything else in the colony, a massive purple slime. The colony's dominant organism. Its body was dense and dark, and the other slimes gave it wide clearance. Not out of respect. Out of the understanding that getting too close to the purple slime, when it was hungry or irritated, meant being absorbed.

  The blue slime was none of these things. It was not acidic. It could not divide. It was not large, not tough, not fast. It occupied no niche. Served no ecological function that any observer could have identified.

  It was simply there. Small and blue and faintly glowing in a cave full of creatures that had no use for it.

  ***

  The slime tried to communicate.

  Slime communication was primitive. Physical contact transmitted simple electrochemical signals: food here, danger, move, stop. The vocabulary of survival and nothing more.

  Unauthorized content usage: if you discover this narrative on Amazon, report the violation.

  The blue slime bumped into a green slime. The green slime's response was instantaneous and disinterested. Move. The signal carried no hostility, because hostility implied awareness, and the green slime barely had that. The blue slime bumped into it again. Move. Again. Ignore.

  It tried a red one. The red slime's surface hissed on contact, a spray of acidic fluid that stung the blue slime's membrane and made it recoil. A warning. Away. Not a conversation.

  It tried a brown one. No signal returned at all. As if it had bumped into a rock.

  Something in the blue slime dimmed. Not a thought. A physical change. The light in its core grew fractionally less bright, the blue of its body a shade less vivid. A small, involuntary darkening that it did not notice and could not have explained.

  It approached the purple slime.

  This was different. The colony's dominant organism possessed a higher order of processing than the others. When the blue slime pressed against its surface, the signal that came back was not a single word but something closer to a classification.

  Variant. Non-conforming.

  A label. Not "move" or "food" or "danger," but a category. The purple slime had assessed the blue slime's nature and filed it under a heading that translated, roughly, to: defective.

  The blue slime retreated to the wall of the cave. It settled into a shallow depression between two ridges of stone, a spot where the moss was thin and the groundwater didn't reach and no other slime had bothered to claim.

  Its core pulsed. Dimmer than before.

  ***

  Days passed. Or what might have been days. In the cave there was no sunrise, no way to mark time except by the rhythm of the dripping water and the slow growth of fungus on the walls.

  The blue slime had nothing to do.

  Other slimes foraged. They competed for the thin film of nutrients that seeped through the rock. They defended territories, absorbed organic debris, divided and recombined in the slow, mindless processes of their kind. The blue slime did none of this. It had no attack capability to compete with. No territory worth defending. It sat in its shallow depression and watched the water drip from the ceiling.

  Drip. Drip. Drip.

  Regular. Predictable. The one constant in an environment that offered nothing else.

  Then one day, moving toward a cluster of mushrooms, the slime caught a ridge of rock with the edge of its body. The membrane tore. A small wound. A single point of HP vanishing from a total it had no way to measure.

  Something happened.

  The core flared. A brief, involuntary pulse of blue-white light, and the torn membrane sealed itself shut. The tissue knitted together, and the pain, small as it was, disappeared.

  [Heal].

  The slime did not understand what had just occurred. But it understood cause and effect. Damage. Then... not damage.

  It tried again.

  It pressed itself against the ridge of rock. Harder this time. The membrane tore again. Deeper. The core pulsed. The wound closed.

  Again. Press. Tear. Glow. Heal.

  Again.

  What began as accident became repetition, and what began as repetition became routine. The blue slime spent its days pressing itself against the rough walls of the cave, opening small wounds in its own body and sealing them shut. Over and over. The same motion. The same small damage. The same small repair.

  It was not training. Not yet. The slime had no concept of skill progression, no awareness that the [Heal] flickering inside its core was growing incrementally stronger with each activation. What it had, and what kept it pressing against the stone long after any reasonable creature would have stopped, was something simpler.

  Response.

  When it bumped into the other slimes, what came back was move or ignore or defective. When it damaged itself, what came back was the glow. The warmth of the core activating. The sensation of tissue repairing, of something broken becoming whole. The only thing in this cave that answered when the blue slime spoke.

  Self-inflicted damage. Self-administered repair. A conversation with itself, conducted through pain and healing, because there was no one else to talk to.

  The other slimes avoided the blue one now. The rhythmic thud, glow, thud, glow of its routine marked it as something aberrant, something best left alone. The blue slime did not care. Or, more precisely, had stopped comparing the indifference of others to anything that might have been different.

  [Heal] rose from Lv.1 to Lv.2. Then to Lv.3. The slime did not notice the change. The cave did not notice, either.

  ***

  The bat fell from the ceiling without warning.

  A juvenile. Small enough to fit in a child's cupped hands, with delicate wing membranes still thin enough to see through. It struck the cave floor with a wet, cracking sound and lay there twitching, one wing bent at an angle that wings were not meant to bend.

  It screamed. A high, thin sound. Rapid-fire squeaks of distress that echoed off the cave walls and silenced the ambient dripping for a moment, the way a sharp noise silences a room.

  A red slime nearby oriented toward the sound. Food. Small, warm, damaged, incapable of escape. The red slime began to move.

  The blue slime moved faster.

  It did not think. There was no deliberation, no weighing of options, no recognition that intervening between a predator and its prey was something that slimes simply did not do. The blue slime crossed the gap before the red one had closed half the distance and placed itself over the bat, covering the small body with its own.

  The red slime stopped. Hissed. A spray of acid hit the blue slime's surface and stung, but the blue slime held its ground. For a creature with no bones, no muscles, no way to brace itself against anything, holding ground was an act of will expressed through the simple refusal to move.

  The red slime lost interest. Turned. Oozed away toward an easier meal.

  Beneath the blue slime's body, the bat trembled. Its wing was bent. The membrane was torn. It struggled weakly, scraping against the stone with its one good wing.

  The blue slime's core brightened.

  Not the dim, functional glow of wall-practice. Something stronger. A pulse that started deep in the core and radiated outward through the entire body, turning the blue slime incandescent. Light spilled across the cave floor. The bat's broken wing was bathed in it.

  [Heal].

  Bone realigned. Membrane knitted shut. The unnatural angle corrected itself, degree by degree, as the blue-white light wrapped the injury and drew it closed. The bat stopped struggling. It lay still for a moment, wing extended, as if testing whether the pain was truly gone.

  Then it folded the wing. Opened it again. Flapped once, twice, three times. Working.

  The bat turned on the cave floor until it faced the blue slime. For a moment, it paused there. Its small nose pressed against the slime's surface. A point of contact. Warmth against warmth.

  Then it launched itself upward, wings beating, and vanished into the darkness near the ceiling. Gone.

  The cave went quiet again. The dripping resumed.

  The blue slime sat where the bat had been, on the spot of stone still warm from the small body.

  Its core was pulsing. Bright. Brighter than it had ever been. The blue of its body was vivid and clear, the translucence restored to something almost luminous. Light radiated outward from the core and lit the surrounding cave wall in a wash of blue, and the other slimes, the ones that had spent days ignoring or avoiding the defective variant in the corner, drew back from the glow.

  Something had happened.

  Not [Heal]. [Heal] happened every time the slime pressed against the rock. This was different. This was the aftermath of healing something else. Something alive, and hurt, and afraid. Something that had pressed its nose against the slime's body before flying away.

  The wall-practice had never produced this feeling. The self-inflicted wounds, the self-administered repairs, the endless loop of damage and restoration conducted in solitude, all of it had been functional. Mechanical. A conversation with no second voice.

  This was the second voice.

  The blue slime could not name what it felt. It had no language, no framework for emotion, no concept of joy or purpose or the ache of wanting something that it had only just discovered existed. What it had was a core that pulsed like a second heart, and a body that shone like a lantern in a cave where nothing had ever shone before, and the warmth of a small nose pressed against its surface fading slowly from the spot where the bat had been.

  And underneath all of it, rising from somewhere deeper than instinct, deeper than the electrochemical signals that passed for thought in a creature this simple, a single impulse.

  Not a word. Not yet. But if it had been a word, it would have been:

  Again.

  I want to feel that again.
