Sovereign Pestilence

Visha Morticia Tanith spent half her life as an experiment for mad scientists who thought it was a great idea to create a serum for supernatural powers. News flash: It wasn't a great idea. In fact, it caused more trouble than it was worth. Luckily, as short as it was, the second half of her life was spent using the supernatural abilities of decay and poison blood as a hired assassin. Of course, that was after she took revenge on the sadistic scientists and her grandfather, who sold her when she was a child. Now, as she dies from the very powers she was forced to have, she gets the great idea to... go to church and confess her sins?
