When the Sky People left, they left behind the Thing. It was flat, and it could bend, and it would not break. It was not food, and it was not a tool, but the Sky People had touched it a lot, so it had to be important.
Thorn poked at it the way she had seen the Sky people do. The figures that came up meant little to her, but the shaking and the red was danger. On the fifth try, she got the pattern that changed the Thing. So many colours. So many different ways the Thing could show her... things.
One of them spoke to her. Words that didn't have meaning, but Thorn was young. Thorn learned. She learned Thing words like "edible" and what "cook" was. And how to make "fire" like the Sky People did. The Thing was useful. Once she could understand it. And one of the first things she understood was that the Thing liked to eat sunshine, but it wasn't a plant. She kept it in daylight so that the LoBatt Warning would never show.
