The government of the Haakonians, which fought a decade-long war against the Talaxians and forced their unconditional surrender by using the Metreon Cascade on the moon Rinax.
The Haakonian Order is the state that rules the Haakonian people in the Delta Quadrant. It waged a war of roughly ten years against Talax, which ended only when the Order used the Metreon Cascade, a weapon designed by the scientist Ma'Bor Jetrel, against the inhabited moon Rinax. More than three hundred thousand Talaxians died and Talax surrendered the next day.
The Order is described in the episode Jetrel, set fifteen years after the attack. Neelix, whose family died on Rinax, says the Haakonians have occupied his homeworld ever since. Jetrel himself has become an outcast among his own people and comes to Voyager hoping to undo some of the harm with the ship's transporter.
