Some time prior to the raid that targeted Ziro's Palace, Ziro the Hutt dispatched the assassin droid known as KRONOS-327 to the twelfth moon orbiting Yout with an assassination mission. However, his assignment was unsuccessful. KRONOS-327 then made his way back to Ziro's Palace, situated on Coruscant, in order to deliver the news of his unsuccessful mission. Ziro, being unhappy with KRONOS-327's lack of success, gave the order to dismantle him for spare parts.
