Squeezing through a couple of particularly tight paths in the cave, you come across a wondrous sight. It's a nearly spherical room with a beautiful pool of water in the center, equally round. The area is lit not my the bioluminescence of the mushrooms you've grown accustomed to, but instead by some source of light in the center of the water.
Against your better judgment, you dip a single touch into the pool - and immediately a brilliant pulse of light swells and bursts out of the fluid; the water itself ripples with the force, though it makes no sound. As quickly as it came, it is gone again, however - seeming to pour into the very walls of the cave and literally trickling away down the hall you just came from.
Left in total darkness, you have to wonder - what the--?
Reaper slowed his pace when the area lit up once again, catching in the sight of those beautiful glowing mushrooms. These patches of fungi seem to be one of his favorite part of this journey, appreciating the sight as they shone around him. The patch he ran into this time seemed to span for quite awhile too, like an endless wall of illumination. Up until he runs into an area that was lit by something else. Looking around the room, his head tilts at the shape of the room, but mostly at the pool in the middle of it. Slowly, he approached it and looked in. The way it shone, it looked like there was a light in the middle of it. Don’t ask him why, he wouldn’t be able to tell you, but he had the strongest urge to reach for the light. And reach he did. The moment his hoof just barely touched the water, he peddled backwards away from the pool when that brightness seemed to explode from the water and along the walls; eventually out the room. Blinking in confusion, he could only think ’I don’t know what that was but… that just happened.’
