Magistrate  
This magistrate, who was responsible for commuting the death sentence of a prisoner, was demanded to be seen as the prisoner was dragged into Doctor Antaak's laboratory. ()

Prisoner  

In 2154, this prisoner was one of the test subjects which Doctor Antaak experimented on in an effort to find a vaccine for the Augment virus. The Klingon prisoner had been convicted of a criminal act, although the magistrate who had presided over the prisoner's trial ruled that the death sentence would be commuted. Shortly thereafter, the Klingon prisoner was brought into a laboratory on Qu'Vat Colony, where Antaak and General K'Vagh worked. As the doctor injected the Klingon prisoner with a green substance, the prisoner's cranial ridges began to ripple and seethe. ()
