Darkness was all it knew until a sound came and then cold a cold current rushed in and its body moved on its own toward the split in the shell into open space.
It stopped and waited. The light was too much at first, everything washing out into white and pale shapes then slowly things sharpened. The ground was covered in dead leaves and dark soil and around it several small creatures were already moving away through the undergrowth, their shapes the same as its own.
It flicked its tongue.
Information flooded its mind from wet soil, rotting wood, cold air, to the warmth of the small bodies nearby, something sharp coming off the tall green things rising in every direction, and underneath all of it a deep damp smell that seemed to come from the ground itself. It was too much all at once and it stayed still until the information stopped feeling like noise.
The others were moving away. It followed them into the leaves.
The ground was uneven, roots cutting through the soil, dead leaves shifting, small stones buried just under the surface. Its body figured this out as it went. Above, the canopy was thick enough that the light coming down was broken into scattered pieces and everything below sat in a dim green shade.
At one point the ground went down where a log had fallen and was stuck against some roots. There was a space, under it. It slid into that space since the ground naturally sloped downward there.
Something came down hard and fast through the canopy outside and one of the shapes moving through the leaves nearby was gone and then the thing lifted back up and the forest went quiet.
It stayed in the gap under the log with its tongue reading the air. Further out the remaining shapes were scattering, their warmth spreading thin until the tongue lost them one by one. The thing above kept moving in wide slow passes over the canopy for a while before that too disappeared from the air.
It came out from under the log when the forest felt quiet again.
The siblings were gone. Their warmth had scattered in every direction and thinned out until the tongue could not separate them from the general air of the forest. It flicked once at the space where they had been then moved forward.
The forest floor went on in every direction looking the same, dim green light coming down in pieces through the canopy, roots breaking the soil into uneven ground, dead leaves covering most of it. It moved without direction, body learning the terrain as it went. A root too high to slide over meant going around. Soft ground near standing water meant slowing down. Stones buried just under leaves meant the surface was less stable than it looked. It collected all of this without stopping.
It found water by following the smell of it downhill, a thin stream cutting between roots and stones at the base of a slope. It drank and then stayed by the water longer than drinking required, tongue reading what the stream carried. Mud and cold stone and something alive upstream, small and warm, moving in and out of the water.
It followed the stream.
Not toward the living thing specifically. Just along the water because the water was consistent and the tongue found it easy to read against everything else. The stream curved through the roots and widened slightly where the ground flattened out and narrowed again where two large stones pushed in from either side.
The small warm thing upstream turned out to be several small things moving through the wet leaves at the stream's edge. One of them stopped when it stopped. It waited. The small thing moved left and its body went before anything decided to go and its jaws closed and the thing kicked twice and was still. It swallowed and sat by the water while its body worked through the first meal it had ever had.
The light was changing by then, the pieces coming through the canopy shifting and slowly fading. It moved away from the stream into the undergrowth and found two roots growing close together with a narrow dry gap between them and went in.
The dark came gradually. Sounds changed with it, some things going quiet and others filling the space they left. Its tongue moved in the still air of the gap, reading the same information in a slow rotation. Stream nearby. Soil. The bark of the roots pressed against its scales. Nothing large moving within range.
It had eaten. Water was close. Nothing was coming.
Its tongue kept moving anyway.
The Sunken Green finished its shift into night and the snake lay in the gap between the roots still reading the air long after there was anything new to find in it.
