The scorching heat of Arra-kiss turned the very ground into a proverbial stovetop, burning or cooking anything that touches it. At least where the sands covered the ground, the insects could bury themselves within the dunes, but in the tough, impenetrable grounds of the barren desert, these insects could only hide within the cracks in the ground, emerging only at night.
Considering that the daylight cycle on this planet was a hundred hours long, that was a long time to stay hidden within a few cracks. But the soil around the treehouse was no longer scorching, even if the shade had only existed for a few minutes.
The burning, insufferable winds suddenly became cool and pleasant as soon as they entered beneath the tree, as if a formation existed around the tree, preventing the boiling heat from entering.
