Trivar II, a planet situated in the Outer Rim Territories under the control of the Galactic Empire, served as a frequent port of call for the Rebel Alliance Intelligence Service freighter known as the Stellar Crawler, which was commanded by Captain Nel Frel. While docked, the Stellar Crawler would hover above Trivar II's northernmost point to facilitate smoother communication with the expanding rebel cell network on the planet. As the assignment was considered relatively straightforward, Captain Frel grew careless during recent visits to Trivar II, leading to a DT-series sentry droid deploying a patrol craft with orders to intercept the Stellar Crawler, but the Rebel Alliance personnel managed to escape.
