During the era of the Galactic Civil War, the Rebel Alliance initiated a major attack targeting Vivonah. Some years following this event, specifically during the peaceful period of the New Republic, Senator Ransolm Casterfo referenced the attack, citing it as an illustration of the alleged terrorist strategies employed by the Rebels.
The very first reference to the Vivonah attack appeared within Bloodline, a canon novel authored by Claudia Gray and published in 2016.
