Sunborns

 are a procedurally-generated, player-controlled sapient species that inhabit a world during and after its generation. The actual traits of sunborn vary wildly based on the world they are generated in, from body shapes to number of limbs to chemical composition to personality.

Biology
All sunborn species are capable of contracting corn fatigue, and the symptoms of the fatigue are per-species.

Generation
Non-player sunborns generate in civilizations throughout the history of the world, some still-standing, others lost to time. As player sunborns are descendants of the sunborns in other civilizations, several aspects of the player sunborns' culture are pre-determined before a game starts.

Gameplay
Sunborns can be controlled as a group to manage colony-building tasks or managed individually to develop their social, cultural, emotional, and mental roles in the colony.
