Spanborn

Spanborn refers to a fictional concept often found in science fiction literature and role-playing games. It describes individuals who were conceived or born in space, outside of a planet's gravity. This environmental difference is typically presented as having significant physiological and psychological effects on the individual.

Physiologically, spanborn are often depicted as having a different bone density and muscle mass compared to their terrestrial-born counterparts, adapted to the microgravity or zero-gravity conditions of their upbringing. This can lead to challenges when they first encounter planetary gravity, such as difficulty standing or moving. Conversely, they might possess superior spatial awareness and agility in low-gravity environments.

Psychologically, the experience of being born and raised in space can shape a spanborn's worldview. They may feel a disconnect from planetary life, or conversely, a profound appreciation for the vastness of space. Their understanding of concepts like "ground" or "up" might differ significantly from those who have only known planetary environments. The concept is used to explore themes of adaptation, identity, and the long-term effects of extreme environments on human development.
