Darona was the sixth planet of the Betazed system, located in the Milky Way Galaxy's Alpha Quadrant. It was home to a small Betazoid colony of which the capital city was Jarkana. Darona has a rose-colored sky and an atmosphere of serenity and natural beauty.
Darona was known primarily as the location of a high security prison for the criminally insane, as well as its agricultural, medical and scientific research facilities. The capital, Jarkana, lay to the east of the Jarkana Mountains. Jarkana spaceport was located just outside the city.
Daronan spring water originated from Darona.
The plants of cavat, crystilia, diomedian scarlet moss, draebidium calimus, frangipani, poinciana and teskalia trees, and zan periculi were grown on Darona.
During the Dominion occupation of Betazed in the year 2374, less than 1,000 Dominion troops were stationed on Darona due to its low population. (TNG novel: The Battle of Betazed)
