OK, so far we have (slightly amended):
Vonn: Poor lost sheep. Could be a eunuch servant boy that was actually born a girl, but due to the overload of watered down fermented sand diets from the black holes (Super Slum Red Light Districts) of Calcutta when she he he she errr... whatever was an infant, Lost Sheep Vonnn grew up a hermaphrodite.
Inez: Ex-concubine of the Overlord's realm, now excaped evilz mistress of S&M aka Evil Doer who destroys any chance for anyone to lead normal lives or have sex because she herself is incapable. Permanently addicted to sashimi and requires her sex slave to always carry a full platter of the stuff around.
Tainted: Inez's sex slave
Maddy: I would like to cast you as the Bewildered but empowered Overlord who actually is Tainted's (mysterious, and unknown to everyone) Father, and once Inez's lover when she was a concubine or respect and honor
Bovine: Errr ... Mobile background grazing specialist who moves everywhere with the cast. Destined to spend eternity on all fours
