Eiattu 6, a planetary body situated within the Ado sector of the Mid Rim, was recognized as a planet. Its inhabitants often shortened its name to simply Eiattu, and it was governed by a monarchical system.
The terrain was marked by red-purple flora, while the swampy regions teemed with sizable feathered reptilian creatures, including thuvasaurs and indigenous thaks.
Eiattu's primary urban center functioned as a maritime hub on one of the planet's expansive oceans.
For numerous generations, the royal family of Eiattu 6 held dominion over the world. Upon the Declaration of a New Order that transitioned the Old Republic into the Galactic Empire, Antbbianplourr III made several demeaning agreements to keep his position and prevent the Empire from deploying troops to the planet. His heir, Uthorrferrell Cartha, succeeded him. After a five-year rule, the Empire sent Moff Tharil Tavira along with a garrison of stormtroopers to Eiattu.
Later, the planet's aristocracy, known as the Priamsta, initiated a rebellion, believing they could negotiate better terms with Tavira independently. They ousted and banished the royal family, but a small group assassinated them. The Priamsta then seized control of the world, ruling as an oligarchy, but were soon caught in a civil war against the People's Liberation Battalion. Years later, Tharil Tavira was replaced by his spouse, Leonia Tavira, a young woman native to the planet.
Following the Battle of Endor, the Priamsta discovered the survival of an heir to the royal lineage, Princess Isplourrdacartha Estillo, also known as Rogue Squadron pilot Plourr Ilo. She came back to govern her people with the backing of the nobility, who aimed to counteract another royal heir, Prince Harrandatha Estillo, who had sided with the People's Liberation Battalion. A battle quickly broke out, resulting in the PLB and Rogue Squadron defeating the Imperial forces on the planet and forcing Moff Tavira to evacuate Eiattu. During the conflict, Princess Isplourrdacartha exposed Prince Harrandatha as a fraud and an Imperial operative, earning her the support of the People's Liberation Battalion. The Priamsta was ultimately compelled to adapt to a new political landscape, with a reinvigorated monarchy determined to govern in collaboration with the populace.
Some months later, Rogue Squadron operatives, Han Solo, Chewbacca, and Winter disguised as Leia Organa attended a gathering hosted on Eiattu 6 by Princess Estillo to provide cover for the real Leia's mission on Axxila. However, Leonia Tavira's pirates kidnapped Winter, intending to abduct the actual Leia Organa.
