The noise initially makes Jon flinch and shine his light in the respective direction, but it quickly becomes clear that whatever is making this noise isn't inside the building. It might well life up on the roof it is climbing onto and Jon can't help but feel reminded of hos the library over in Temba is being overtaken by mothcats despite the presence of people.

He sighs and heads further inside, pausing as the shelves that are just as empty as the ones in Temba, but notably fewer. And made of stone. The entire building is smaller, more compact in its design and these shelves hardly look as if they ever held books or even data points.

The stomping from above pulls his attention away from the shelf again as whatever wanders around up there crosses right over Jon's head, causing a fine drizzle of dust and debris to crumble down on him.
