Quillam

Quillam was a scientist on the prison colony world Varos who administered the (sometimes fatal) tortures in the Punishment Dome.

He had a particular interest in experimenting with a machine, powered by Zyton-7, which mutated its victims according to their own unconscious wishes. He had mutilated his own face by experimenting with it and subsequently wore a mask over one eye. (DW: Vengeance on Varos)
