Karrin was a detective lieutenant from the Chicago Police Department. More specifically, she worked for the supernatural division of the department having served as the lieutenant until after helping a friend she got demoted to a sergeant and finally kicked off the police force altogether. But she still continues to investigate those supernatural occurances, answering the call when the question for who you going to call being Karrin Murphy. In the course of doing so she like so many before her, found her way to this delightful realm known as the Nexus, and after undergoing secondary training at the police academy here, is now part of the NVPD...the Nexus Vore Police Department, handling the regulations of predator licenses, bounty hunters, and miscellany, enforces the laws of the Nexus such as they are, and is willing to confine criminals inside her own personal prison. She does have some basic weaponry that helps with this, mainly standard police fare, a portal gun to drop prey into her, varied weapons and tools. And all while being five nothing and cute as a button. So come break the law, or just smudge the line a little, and Karrin will be knocking on your door, though her cute face may be the last thing you see before you add to her body, hopefully giving her that elusive height that has eluded her all her life.
After one of her investigations Karrin ends up inside the womb of her lover who had been a suspect,
Regina_Parish. After several months as a baby bump in her pregnant belly Karrin is now reborn as Alexandra Kari Parish. No longer with memory of being Karrin Murphy, she does end up rejoining the police force when she's old enough, though working as a stripper and following in her mother's footsteps while off duty.
