The deep, dark, abysmally black night had fallen. Low down at the western horizon Earth hung, blue-green and glamorous, just above the crests of many ring mountains. It was a little past first quarter, and it gave only the faintest of light to the tortured and splintered rock formations outside Grimaldi Base.
