Omman became the site of an Imperial garrison after the fall of the Galactic Republic. The Empire used the planet as a base from which it could keep watching the Mon Calamari and Rebel activity in the troubled Back Spiral.
Behind the scenesEdit
The planet Omman was created in When the Domino Falls, near Socorro. But after an other Omman was mentionned in the Tion Cluster, the first was identified as Omman Minor by the The Essential Atlas Online Companion. Although it was published later, The Essential Reader's Companion didn't noticed this retcon.
