During the High Republic Era, Queen Nyla, a Hynestian, held the position of ruler over Hynestia Prime.
Hynestians, the inhabitants of the Colonies planet known as Hynestia Prime, were once renowned throughout the galaxy for their extensive travels and occasional conquests. However, by the era of the Galactic Empire, their primary occupation was farming a fur-resembling lichen called gherlian fur.
During the Imperial Era, Hynestians residing on their native planet were governed by the Empire-supported Hynestian royal family. This family maintained a private fleet and a security force to maintain control over the population. Nevertheless, the Hynestian military was outmaneuvered by the smuggler Lando Calrissian, who assisted a rebel royal family member, Princess Rinetta Gan, in the retrieval of a sacred artifact from the planet Livno III.
As part of the extensive Citizens' Fleet, a collection of volunteer civilians gathered from across the galaxy by Lando Calrissian, a number of Hynestian Star Cruisers participated in the Battle of Exegol. This armada aimed to defeat the resurrected Galactic Emperor Darth Sidious, who represented the returning Sith threat.
