David Chaste: 
Director David Chaste was the head of the dreaded "Female Experimental Modification Division" (FEM-D) in the nation of SanVeritas.  Where his mandate was to "Improve the performance and training of female slaves"
David used his position to oversee countless cruel procedures conducted on enslaved women.  as has been described in "Conversion Nation"
David thought he had finally reached his goal of removing female free will when he invented the nano-filament cyber-mesh that allowed computer control of a person's entire brain.  Enslaved women no longer needed to be broken, or trained.  They could simply be controlled with the touch of a button or the issuing of a voice command.   They could even have their minds overwritten with the recorded personalities of more obedient slaves. 
This was all flipped when David was betrayed and his inventions were turned against his nation.  In the chaos of the "Mesh-Puppet Uprising" David was captured by his own formerly mind-controlled agent "Grace" and taken to the island compound of the sinister "Dr. Kat Lilith" who we met before in "Intended Side Effects."  Dr. Lilith is determined to see that David suffers just as much as the women who passed through FEM-D.
