The cities of the planet are sprawling metropolises where the rich live in the lap of luxury. The citizens of the planet have a natural ability to glow in the dark to varying degress, which has created a caste system where those who can fully glow have opportunities in life and those who can't are stuck at the bottom of the socioeconomic ladder.
