A perfectly round sphere of light hangs suspended in the air, casting an otherworldly glow on the rough, damp walls of a long, dark tunnel. The source of the light is unclear, but it seems to emanate from within the sphere itself, pulsing with a soft, inner luminescence. The tunnel stretches out in both directions, shrouded in shadow, and the only sound is the faint drip of water echoing from the unseen depths.
