Carceri
The six layers of Tarterus had a seemingly infinite number of worlds arranged like a string of pearls stretching into the air-filled void. In the top layer, Othrys, each orb was about the size of a Prime Material world and averaged about 100 miles (160 kilometers) from the nearest orb. In each successive lower layer the planetoids grew smaller and farther apart. There was no sun but the soil of each orb gave off heat and a dull reddish glow, similar to the phosphorescence of fire beetles . The planets did not rotate and there was no day or night unless a greater deity wished it so in their realm. Seasons and weather occurred randomly and what little plant life there was would rapidly mature after rainfall and then wither hours later. Each orb was connected to one specific Prime Material world.
