Dust.
The sun never set in Solis. It rolled back and forward across the sky, teetering atop dust clouds, its scorching glow forcing thorough tight shutters and curtains designed to keep it out. When we went outside, we shielded our retinas with thick goggles, and draped our skin in heavy cotton - we weren’t to expose ourselves, though its fierce presence was always felt. From when we were young, we heard stories of how the heat from the sun had sucked up the water, and of its immense brightness that was capable of blinding us if we looked at it. So, we lived in the shade of large sandstone buildings, roofs towering over our heads as we swarmed together like flies.
