The droid of annihilation, Annihilation Droid XRR-3, which its maker Soa called Silentior, had the initial purpose of civilizational destruction in the era of the Infinite Empire. However, it was later re-tasked to safeguard the Eternity Vault jail on Belsavis throughout the Cold War, preventing any entry or exit. A broad attack was used to scatter foes in close proximity. Furthermore, it possessed the ability to launch a lethal barrage of missiles, posing a significant threat to opposing forces. Moreover, its Storm-protocols allowed for the absorption of enemy strategies, facilitating robust self-defense.
