This story is very dark.  It is in fact, horrific.  Do not read past this page if you are triggered by any of the following; violence, Threats of death, Medically unnecessary surgeries, Amputation, Mutilation, Non-Consensual Sex, Slavery

Carol has been captured by an evil Empire that enslaves women.  As a rebel, she has been shipped to the sinister Female Experimental Modification Division (FEMD) as a test subject. 

Because of her resistance, they decided to make an example of her.  Now she faces a fate far worse than slavery or death

Bound Fantasy Tales  has put together a single post with all the FEMD captions in one place.   It's an excellent introduction to the world where Conversion takes place.
