Wellerman – series I

Gravity and Origin
Some musings on and toying with more nuanced and variable gravity rules for The Expanse TUE. I suggest allowing characters to move more effectively in typical gravities of their habitats. And suggest moving towards picking native gravity rather than cultural or faction belonging.
