From the introduction: Years have passed since the fall of Earth, when the sins of humanity brought fire and darkness, when angels did battle with the demons of hell and Satan walked the lands. Though the lord of hell was defeated, Earth was lost. But the faithful endured, warned by the Lord of the coming Armageddon. Leaving their former home in great ark ships, the righteous left Earth behind so that humanity might live on amongst the stars, free from the sins and corruption that lay waste to their ancestral home.
