One word: paradise. The cloud barrier is a reflection of the lights seen in the cave. A sign, more or less. Stuck between a wall of fallen trees and an enormous boulder in Siberia is the entrance to a cave. The entrance takes you down a long dark tunnel and spits you out into a cavern large enough to fit several major cities. A wide river cuts through the cave, splitting it in two. The water glows a light blue. The animals and plants all glow in a myriad of colors as well. It's beautiful, to say the least. The water is safe to bathe in and drink from, so many, many people love here in makeshift houses.
