(Here's the second update for today. We'll be back to regular updates from tomorrow.)
This is a strange and peculiar world, constructed of ice and snow.
This is a cave that spans only a few hundred square miles. The wind comes into the cave entrance, its warmth and humidity swirling within the cave. The moisture in the air turned into drifting snowflakes under the cave's low temperatures. The wind, now bereft of warmth and humidity, carries the piercing cold and the ground's accumulated snow from the cave's exit.
"It's so cold." A frail Vivian rubs her red, frozen face, muttering a complaint. "I wish we had brought tents. At least they would block the wind."
