Sunday is a planet that has been colonized by Humans in the year 2107. It is a mostly oceanic world with only a few insular land masses on the equatorial zone, which are almost entirely dominated by a swamp environment.
The planet has a rotation period considerably shorter than Earth, a gravitational pull of 0.9 Earth's normal, and orbits an orange sun. Its land flora is dominated by green trees with silver-grey trunks, and its native wildlife includes a species of intelligent otter-like creatures, as well as 'gators, water pigeons and numerous other species which resemble Earth's birds, fish and worms.
