From the introduction:
Enter the Slave Pits, where the wretched are sent to perish. You have stepped away from the light of life-giving Shamash; your trespasses have forced the divine eye of the heavens to dismiss you into the shadows, for if you ever met his gaze again his flaming wrath would surely strike you down.
But one day, maybe, you can win your freedom back: by hard work, by cunning or by blood in the Sun’s court.
The adventurers are thrown into the slave pits under Sippar, accused of a crime they did or didn’t commit. The adventurers' goal is to survive the slave pits and escape them. But there are secrets hidden in the shadows: both in the heart of their fellow slaves and in the dark soil they tirelessly tunnel.
