Something heavy had reached the field.
The pale edge folded toward me.
One cap.
Ten.
Then too many to count.
Blue light spread beneath them in overlapping lines. The nearest strands tightened against the stone while farther sections lifted as if something beneath them had pulled in several directions at once.
I moved backward.
My right lower tentacle still responded a fraction too late. My foot produced less mucus than before. The stone ridge behind me stopped my shell from rolling, but it also blocked a straight retreat.
Behind the ridge was the slope.
Behind the slope was the hidden channel.
Inside the hidden channel was the reason the field had suddenly become enthusiastic.
Crk
The vibration travelled through the stone.
A section of gray fungus above the hidden channel bulged outward.
Pale mouthparts broke through.
The feeder tore the obstruction apart in three bites.
Its head entered first. The hooked structures beneath its body caught the edge of the opening. Its thicker middle compressed behind it while torn fungal membrane dragged across its back.
It paused.
I stayed still.
The feeder's front hooks tapped against the stone.
Once.
Twice.
Its head turned.
Not toward me.
Toward the living seam running along the channel wall.
The seam continued beyond the broken obstruction and spread into the pale field.
The feeder lowered its mouth.
Bite.
Blue light flashed through the fungus.
The feeder pulled itself forward.
Bite.
Pull.
Bite.
Pull.
It had entered the cavern.
Not for me.
That should have been comforting.
It was not.
Being ignored by something capable of eating the ground beneath me only improved the situation in a very technical sense.
The feeder crossed the boundary.
Its front hooks pressed into the pale mat.
A wave of caps folded around them.
Spores burst upward.
Not the faint cloud I had triggered.
A thick pale mass covered the feeder's head and front body.
It stopped.
My tentacles extended slightly.
The feeder's mouthparts opened and closed without finding the next bite. Its head shifted left, then right. The front hooks scraped against the stone beneath the field.
The spores were working.
Good.
Possibly.
The feeder twisted.
One hooked structure tore free of a closing cap. Another remained caught beneath folded tissue. Its body bent around the trapped point.
More caps closed.
More spores rose.
The feeder pulled backward.
For one hopeful moment, I thought it would retreat into the channel.
Then its mouthparts found living tissue again.
Bite.
It removed the cap holding its hook.
Swallowed.
Continued.
'Of course.'
The spores had slowed it.
They had not convinced it to leave.
Its body tolerated more exposure than mine, or it removed affected tissue before the chemicals mattered, or it was becoming numb and had simply failed to recognize that as a reason to stop.
The last possibility felt familiar.
The feeder bit into another pale section.
Blue light surged ahead of its mouthparts.
Several paths brightened. Most faded quickly. One continued deeper into the field.
At the next junction, the feeder paused and tapped across the surface until its mouthparts contacted another living strand.
Then it followed it.
Not the thickest cap.
Not the nearest loose fragment.
Connected growth.
I already knew connection mattered inside the channel.
Now the feeder was exposing where those connections went.
Its rear body cleared the opening.
The cavern shook beneath its full weight.
Every cap near the boundary folded.
Blue light spread in broad waves.
The field was no longer a wall.
It was a map being damaged in real time.
A dangerous map.
An involuntary map.
Still better than no map.
The feeder advanced.
A cluster of thin caps to its left closed before its body touched them. A hidden connection had carried the response first.
To its right, a thicker section remained open until one hook pressed directly into it.
Different timing.
Different routes.
The mound reacted too.
Several dull blue lines brightened beneath its outer layers, then disappeared.
No pulse returned toward me.
No answer.
Only reaction.
Probably.
The feeder reached a split in the living seam.
One branch curved toward a dense cluster of caps. The other passed through a darker strip with fewer visible growths.
It touched the first branch.
The nearby caps closed.
The feeder pulled away, shifted toward the dark strip, then returned when its mouthparts found the first branch again.
The cap closure had interrupted it.
It had not redirected it.
My first theory had survived less than a minute.
An improvement over several earlier ones.
A vibration reached my foot.
The feeder was moving closer to my side of the field.
Not toward me.
Along a strand that happened to curve along the boundary.
The difference remained important.
The consequences remained similar.
I looked toward the marker.
[Location: Fungal Cavern]
[Distance: 6.4 meters]
The number had not developed sympathy.
The growth between me and the marker closed in waves around the feeder. Sections behind it reopened slowly. Some remained crushed. Others released spores and went still.
I could wait.
The feeder might continue away.
It might also follow the boundary strand until it reached me.
Returning up the slope meant entering the hidden channel behind it.
Bad.
Staying beside the ridge meant trusting its route to change.
Worse.
Crossing the field meant entering the surface I had just confirmed reacted strongly to my mucus.
Excellent collection of choices.
Behind me was a larger mouth.
Ahead was an ecosystem that may or may not have answered me.
The ecosystem won by a narrow margin.
The feeder bit through another cap.
A broad spore cloud drifted across its body.
Its movements slowed. One front hook struck too far forward and slipped between two layers. The feeder twisted to free it, pulling several caps sideways.
The surrounding tissue folded around the disturbance.
Behind it, several caps remained crushed and dim.
An opening.
Not a safe one.
The damaged section might react more slowly.
It might not react at all.
I touched the bare stone beside the boundary with one lower tentacle.
Then the first pale strand.
Nothing closed immediately.
The feeder's movement had already sent a pulse through it.
A heavy scrape followed.
Closer.
One side hook reached the same boundary branch I had tested before.
The strand brightened.
Blue light moved toward me.
The nearest cap began folding.
Decision made.
I moved onto the field.
The surface tightened beneath my foot.
Fresh mucus spread over it.
Blue threads brightened.
I kept moving.
One contraction.
Then another.
My shell pulled backward as the mat rose slightly beneath me. I flattened my foot and shifted my weight before it could tip me.
A cap folded behind my shell.
Too close.
I moved faster.
For a snail.
The phrase had become an insult.
A pulse travelled beneath me toward the mound.
Another came from the feeder.
They crossed under my body.
The pale strands tightened.
For one second, everything around me became rigid.
I stopped.
Moving increased the reaction.
Stopping left me sitting on it.
Excellent.
The feeder tore through another section.
Its pulse reached the nearby caps first.
They folded.
The tension beneath my foot released.
I moved during the change.
One contraction.
Two.
Three.
Then several more while the caps remained closed.
The mat dipped into a shallow depression ahead. A damaged cap lay across it, split through the middle. Gray tissue showed beneath the luminous surface.
I climbed onto it.
No closure.
No spores.
Dead or too damaged to respond.
Useful.
I stayed there long enough to let my foot recover.
Behind me, the feeder entered the section I had crossed.
Its hooks pressed into the pale mat.
The response spread around it and passed beneath my resting place without closing the broken cap.
The damaged tissue was a gap in the network.
Or only a gap in its response.
Not necessarily the same thing.
The feeder's weight crushed another cap.
A dark line appeared beneath it.
Not a shadow.
Almost black fungal tissue ran through the pale mat, hidden beneath the overlapping caps.
The feeder shifted.
More of the strip became visible.
It curved away from the boundary and continued deeper into the field.
Generally toward the marker.
I checked the distance.
[Distance: 6.37 meters]
Progress.
Three centimetres.
Enough to confirm direction.
Not enough to celebrate.
The dark strip contained fewer caps. Its surface looked firmer than the pale growth around it. Blue light moved beneath it in thin, delayed pulses.
A safer path.
Possibly.
The cavern had already taught me what safe-looking surfaces did.
One final cap peeled away as the feeder passed.
The dark route continued toward the mound.
Fewer spores.
Less movement.
A direct line through the field.
That immediately made it suspicious.
