A Delta Quadrant people living under the oppressive military government of the Mokra Order, whose resistance movement helped Captain Janeway to free her captured officers in 2372.
The Alsaurians are a humanoid species who appear in the Voyager episode Resistance. Their world is ruled by the Mokra Order, a suspicious and brutal regime that watches its citizens closely and imprisons those who oppose it.
Needing tellerium for the warp engines, Janeway, Tuvok, Torres and Neelix go secretly to buy it from the Alsaurian resistance. Mokra soldiers raid the meeting. Tuvok and Torres are taken to prison, while the injured Janeway is hidden by Caylem, a gentle and confused old man who takes her for his long-lost daughter.
Janeway finds allies in the resistance and enters the prison with Caylem. There the Mokra commander Augris cruelly tells him that his wife and daughter died years ago. Caylem kills Augris and is mortally wounded, and Janeway lets him die believing that she is his child.
