i have small setting for these ladies.
after an apocalypse, the nature of planet Earth and its people are starting to recover. most of the old governments have fallen and there's not a new one yet, but people are gathering into their own groups and forming small societies that help each other. there are lots of criminals and random road warriors roaming in the deserted areas, but people are relatively safe and defend their homes together.
some places are harder to secure than others, often due to environmental causes like having bushes and forest around the small villages - people don't want to cut down the vegetation because it has just started to grow well and it's extremely important to keep growing, but it gives cover for stealthily advancing attackers.
McCoy has attained a reputation of an almost inhumanly strong warrior and a fair, brave and good-hearted person. she was welcomed to stay in a forest village when she promised to help the inhabitants to protect their homes. McCoy lives near their primary water source, a well and its surrounding plants, and keeps an eye on it. the villagers like and appreciate McCoy, but they are rather scared about her companion.
before the apocalypse, Candy Cotton used to be a notorious serial killer known for her small size and extremely destructive and vicious style to snuff off people (most of whom were criminals and corrupt officials). she was thought to be dead and was not seen for decades, until she reemerged on McCoy's side. Candy behaves well and helps the village with McCoy. she is feared and the inhabitants tend to avoid her, but since she is on their side, they give her respect. Candy lives with McCoy in their house. the old couple loves each other dearly. after being torn apart for almost her whole life, Candy finds calmness and safety in McCoy's arms, and doesn't care about anything than the life they share.
