Human Variance

Humanity evolved to thrive on Earth, with its gravity of 1g. Birth and growth on space stations and other planets creates many changes in the human body, which can result in radically different body types and both health and psychological problems when introduced to a new environment.

 High Gravity 

High Gravity humans were born and raised on Earth or Venus (which has gravity of 0.7g, not low enough to result in significant differences). These are standard humans with no unusual variance from the norm.

High Gravity humans often see a strength boost when in low gravity, as their muscles are highly developed by comparison, and are more physically fit than Low Gravity humans. However, they take time to get used to the Coriolis Effect of spinning station gravity and physics and walking in low gravity (start with Quirk: Nauseated and confused by spin gravity and Quirk: Difficulty in low gravity).

 Low Gravity 

Low Gravity humans were born and raised on Luna, Io, Mars, or Pluto. The low gravity results in development of very tall, thin, and gangly bodies reminiscent of Marfan Syndrome. Heights of 2 to 2.5 meters are not uncommon, but their build is very slight.

The lack of muscle and bone development makes Low Gravity humans very weak under full gravity (maximum starting ST 7), which presents a serious danger: they require oxygen masks to breath on Earth or a space station with their weakened lungs (treat as a -10 point Disadvantage) and suffer joint pain (Affliction: Moderate Pain) at approximately 1g. Injections of ursaline (weekly on Luna, Io, and Pluto and monthly on Mars) are necessary to avoid more severe atrophy and to strengthen the muscles and bones in full gravity. Because of their life restricted to vacuum-sealed environments, they begin with Agoraphobia. They also have the same problems as High Gravity humans with station gravity (start with Quirk: Nauseated and confused by spin gravity) and may have accidentally destructive habits from expecting low gravity on Earth (start with Quirk: Difficulty in high gravity).

 Station 

Station humans were born and raised on a space station, under the influence of 1g provided by spinning the station. While this allows for ordinary bone and muscle development like High Gravity humans, it also results in behavioral quirks from the Coriolis Effect.

Station humans are used to accommodating for the spin when performing tasks like pouring liquids, which can result in embarrassing messes when under regular planetary gravity (start with Quirk: Confused by planetary gravity). Because of their life restricted to vacuum-sealed environments, they begin with Agoraphobia. As they live under standard gravity, walking in low gravity and understanding its physics can be difficult (start with Quirk: Difficulty in low gravity).
