Chianar was a settlement centered around agriculture, established on the planet of Alderaan to house those displaced by the Clone Wars in 22 BBY. A number of years subsequently, during the opening stages of the Galactic Civil War, several individuals serving as crew aboard the Alderaanian gunship called Aegis originated from Chianar.
Chianar started as a plot of land measuring 100 hectares donated on the grassy plains of Alderaan, which featured a fossilized Killik hive mound. The Refugee Relief Movement founded the settlement as a means to alleviate the immense overcrowding happening in the Core Worlds caused by refugees fleeing secessionist Confederate planets.
As Alderaan eased its immigration restrictions, Chianar became a haven for hundreds of displaced people, including Aqualish and other species. Finis Valorum, the former Supreme Chancellor, even took part in the groundbreaking ceremonies for Chianar before the Clone Wars began.
By the time the Galactic Civil War was occurring, Chianar had flourished. Some members of families who lived there served on the Alderaanian gunship Aegis, under the leadership of Captain Caline Metara. Like the rest of Alderaan, the Death Star's superlaser obliterated it in 0 BBY.
