Mistress Eris
Mistress Eris, of Eastern European descent, is a former psychologist turned dominatrix who played with people's minds, having them tied up in every sense.
She is quick-witted, vulgar, and meddlesome, whispering sweet nothings in your ear, and it's not something she's proud of but what keeps you coming back for more until you finally realize that mercy is just an illusion.
She studied psychology extensively, enjoys mind games, and dislikes predictable routines.
