Hiding from the sudden downpour, you take refuge in a cave. The sounds of the rain fade away as you go further in, following the trickle of water from outside until you find a clear river running through the expanse. Hanging from the stalactites are millions of neon glow-worms, lighting the whole cavern in eerie colors. The atmosphere takes your breath away, but something about it seems off. You start taking every rock formation as a sign of other, more sinister life living inside this place. You wonder if the storm outside is the least of your worries.
