Martian

They still dream. They're an entire culture dedicated to a common goal, working together as one to turn a lifeless rock into a garden.

Martian
Born in the Martian Congressional Republic, your life has been influenced by the Martian dream to terraform the Red Planet into a lush and life-sustaining garden. Like the generations before you, you know that you will likely never see the completion of this work in your lifetime. As a Martian, your character has the following traits.
Your native gravity is low, the gravity of Mars rahter than Earth. Martians are more comfortable with microgravity than Earthers and better able to tolerate a full 1g than Belters.
