The Confederation Rock Rush was an event that occurred in about 31 BBY when the Smuggler's Confederation, led by the Oblee Nirama, opened up the Cularin system asteroid belt for exploration. Starships from all over the Cularin system, such as the transport Daring flocked to take part. Some were damaged by the dangerous asteroids while others ended up fighting each other over claims to newly-discovered asteroids. The Heroes of Cularin participated and they discovered an asteroid containing a survivor of the Sibilaari species.
