The oppressive military government of an Alsaurian world in the Delta Quadrant, which captured two of Voyager's officers and was resisted by an underground that included the deluded old man Caylem.
The Mokra Order appears in the Voyager episode Resistance. Needing tellerium to keep the warp core running, Janeway leads a covert landing party to buy it from the Alsaurian underground, since the Mokra are hostile to outsiders. Soldiers break up the exchange and seize Tuvok and B'Elanna Torres, who are interrogated in prison.
Janeway is sheltered by Caylem, a gentle and confused man who takes her for his daughter and believes his wife is still held by the Mokra. With his help she enters the prison while Chakotay negotiates fruitlessly with the Mokra magistrate Augris.
In the confrontation Augris cruelly tells Caylem that both wife and daughter died years ago. Caylem kills him and is mortally wounded, and Janeway lets him die believing his family forgave him.
