After touring under the sun for a few hours, the Envoys' curiosity was mostly slaked for the day, and they were ready to return to the city and see what it was like on the inside. The outside had been incredible, and the fresh air and waving grass of the dig site were comfortable enough that the Dryad and the Shin were unwilling to leave, but they also weren't willing to be left outside overnight since there were no other trees in the area, and sleeping in the grass would inevitably lead to being invaded by hostile alien insects.
How hostile was the question, since the insects here were mostly only the ones necessary to facilitate composting, but that didn't mean that they wouldn't be a real nuisance to plant-based species far more than they were to the Hunters, who would be sleeping in their shuttle.
