Serenity O'Share was born and raised on the Planet Terran Tor. Her people are legendary across the galaxy, nicknamed the fierce "Amazon's".
An Old Earth 1.0 colony from Ireland brought the usual million settlers to this wild location. The local fauna proved so deadly, most of the military and security personnel landed were decimated in the first two waves. This skewed the population into a gross imbalance in favor of females about 60%, to 40% males remaining in the colony. Women took on most leadership roles.
From ariel platforms, the more dexterous female sharpshooters quelled the indigenous fauna enough that the colony could finally land on one of the larger island continents and begin farmsteading operations. Terran Tor assumed a matriarchal society which survives as such to this day.
