If the Trolls are truly a specie that are afraid of the sunlight like Orun had assumed, they will have a hard time living in the desert composed of sand and the harsh raining down of the sun.

Orun had stayed quiet for too long, with his eyes still in the direction of the Trolls cave, looking at it like something was going on there.

Orun did not want to jump to conclusions on his assumptions, not when he had someone to confirm from at least.
