They descended through a maintenance hatch behind a decommissioned heat exchanger. The air changed. The amber glow faded to a bruised purple, then to nothing. Elara lit a small chem-lantern. The tunnel walls were covered in old tile advertisements for a drink called Glacier Fizz —a brand that had died with the ice.
