Three months in and the Sunken Green had stopped being overwhelming.
It knew the stream and where it widened and where it narrowed. It knew which roots hid the small jumping prey and which patches of ground stayed wet long after rain and drew the slow crawling things out in numbers. It knew the spots where the canopy thinned enough that the large winged hunters could drop through and it avoided those without thinking about it anymore.
The forest had become a collection of known things and the spaces between them.
It had grown. Not dramatically but enough that the gap between the two roots where it had spent its first night was too narrow now. It had a new place further along the stream where a flat stone overhung the bank and left a dry shelf just above the waterline. Cool in the day and sheltered at night and close enough to the water that the tongue always had something to read.
It was under the flat stone when the light came.
Not daylight. The sun had been gone for hours and the Sunken Green was in its full dark, the canopy overhead blocking even the moon. This light was different. It came from one direction and it was warm and it moved, not the way prey moved, not the way anything moved. It flickered. It pushed back the dark in a way that nothing in three months had done and the tongue found heat coming off it that matched no living thing it had encountered.
It came out from under the stone.
The light was coming from deeper in the forest, through the undergrowth, past two ridges of root and a dense cluster of tall straight trunks. It moved toward it slowly, staying low, reading the air as it went. The tongue found something else underneath the strange heat. Several warm bodies, large, larger than anything it had learned to hunt, sitting close to the light source. And underneath that the smell of something that had recently stopped being alive, blood and opened flesh, heavy in the cold night air.
It stopped at the edge of the undergrowth where the roots of a large tree broke the ground into a natural barrier and looked through the gap at ground level.
Four of them. Tall, two limbed, wrapped in layers of material that covered most of their warmth signatures. They sat around the fire on fallen logs and flat stones, some of them holding things over the flame, one of them doing something with its hands that it could not make sense of from this distance. The fire sat in a shallow pit they had dug in the forest floor and it burned steadily, orange and gold, throwing light out in every direction and turning the trees around the camp into long shadows.
It watched the fire for a long time.
The tongue kept reading it. Heat, yes, and something chemical underneath, wood breaking down into something else, the smell of it sharp and foreign. It was not alive. It was not prey. It was not a threat. It was just a thing that burned and gave off heat and light and it had no category for it yet.
Then one of the large creatures made a sound.
The others responded. Back and forth, sounds going between them in a pattern, some short and some longer, some flat and some rising at the end. Not like the forest. Not like anything the forest did. The forest made noise because things were happening in it. These sounds were happening because the creatures were making them happen, pushing them out deliberately, and the others were receiving them and pushing sounds back.
It stayed completely still at the base of the root.
One of the creatures stood and moved to the edge of the camp where several dark shapes were piled on the ground. It crouched and did something with its hands and then held something up toward the fire to look at it. A small dense object, dark, that caught the firelight. The creature made a short sound and another one responded from across the fire without looking up.
It had no way to know what any of it meant.
But the sounds had a structure that the tongue could not stop trying to follow, patterns inside patterns, certain sounds appearing repeatedly in different combinations. It tracked them the way it tracked movement in the undergrowth, the same automatic attention pulling at it without being told to.
The fire burned lower as the night went on. One by one the creatures wrapped themselves in material and lay down around it until only one remained sitting up, making sounds occasionally that the others no longer responded to. Eventually that one lay down too.
The forest went quiet except for the low crackle of the dying fire.
It stayed at the base of the root until the fire was nothing but faint heat coming off dark coals and the tongue could find nothing awake in the camp. Then it moved back through the undergrowth toward the stream and the flat stone and coiled there in the dark.
The sounds the creatures made kept running through whatever it used to think with, the patterns of them turning over and over, incomplete and full of gaps, meaning nothing yet.
It did not sleep for a long time.
