Incident in the Obroa-skai system

During the Berch Teller campaign in 14 BBY, the insurgent leader Berch Teller transmitted disinformation that the corvette Carrion Spike was traveling to the Obroa-skai system. Knotts, one of Teller's dissidents, hired the Koorivar captain of the YT-1000 freighter Reticent to travel to the Obroa-skai system as a decoy. Acting on this information, Moff Wilhuff Tarkin and Darth Vader deployed three Imperial interdictor vessels into the Obroa-skai system, hoping to recover the stolen Carrion Spike.

However, the Immobilizer 418's gravity well projector malfunctioned and yanked several civilian ships out of hyperspace, including the luxury MC80 Star Cruiser Stellar Vista, the smuggling vessel Truant, and the Reticent. The Stellar Vista collided with a Detainer CC-2200, damaging both ships and causing the deaths of 1,100 civilians. Despite failing to capture Teller's dissidents, the Imperials managed to destroy the Truant and capture the Reticent. After interrogating the captain and his crew, Vader and Tarkin learned about the identity of Teller and his dissidents.
