The Eridani System was a backwater system not of high value, used mainly by big industrial corporations and smugglers. It was taken by the Altarin'Dakor in 14 ABY. The New Imperium, sent a mission called Operation Spear, led by Walt Amason, that used the NI's World Devastators to destroy one of the enemy's Titan-class Battleships, the Annihilator. In retaliation, the Shok'Thola Nimrod caused the system's star to go supernova, destroying the whole system, including the Titan, the Devastators, and the planet Eridani.
