From the introduction: You arrive, and the first thing that hits you is the cold. From the position of the Sun in the sky, it should be a warm, bright Summer afternoon, but the light shining down on you through a break in the clouds is gloomy and weak, somehow lacking the warmth it should have as it struggles to pierce the thin, grey murk that blanket the sky. Already your breath is steaming in the cold air, and breathing is starting to become painful as the icy chill rakes at your lungs.
