Around the time of 6 BBY, an act of stealing happened at the Lozash naval yard, and one of the stolen items was an Imperial masking unit. Subsequently, in 5 BBY, which was a year later, a rebel pilot, having previously transported provisions for Kreegyr and his team, employed the masking device during a journey to the Ring of Kafrene located in the Expansion Region. While utilizing the masking device, the pilot briefly displayed an Imperial-registered profile; however, the Empire apprehended the pilot, uncovering both the masking device and its source at the Lozash naval installation.
