You walk through the icy tunnel, pushing a mine cart back down to the cavern, so it can be loaded up with dust crystals and pushed back up to the surface again to be unloaded. A strenuous process, sure, but there are worse jobs.

You eventually reach the large cavern, where you see many armed guards keeping watch over you and your comrades, the cave littered with various dust veins.

You lean against the cart and think about continuing to perpetuate your miserable existence... Or rebel.
