Squornshellous Zeta is a planet in the Squornshellous system and home to the Mattresses. It is covered with marshes and swamps which are in turn covered by a thick mist that hangs motionless like held breath. Often entire days pass in silence and motionlessness, and the sun, despite its best efforts to impart a little warmth here and shed a little light there, finishes its long fourteen-hour haul across the sky by sinking hopelessly beneath the horizon with a sense of totally wasted effort.
