As night sets in, the canyon grows stranger, and when you look up you could swear something moved in the darkness as the last of the light fades to a dim, formless grey; an unsettling sensation ripples up the length of your spine, but perhaps it was just the oncoming chill. The Wastes had turned into a veritable hellscape beneath the relentless plague-sun, but once the stars emerged and the world had fallen into a quiet hush, the air became frigid, the ground growing as cold as the ice-sheets of the Alpines until you could see your breath coming out in plumes of steam until the chill seeped into your bones.
Yet you remain undeterred.
Frolicking carelessly through a canyon now wreathed in shadow, you fling yourself off of the next rock - but your ankle twists - and you yelp out in surprise as you tumble down, down, falling head over paws until you find yourself in a small crevice wedged against the base of one of the cliffs. You quickly assess yourself for damage, determining you're mostly unharmed (if bruised) - then something twinkles and catches your eye, a stone slab partially submerged in a small pool of water in an alcove further ahead. You're surprised to see any water this far into the canyon, but then again, natural springs could form anywhere; even the desert.
Even here...a soft voice whispers pensively in your mind, although you don't think it's talking about the pool.
Do you fetch it out?
