The Annihilator represented a hypothetical superweapon that was supposedly being engineered on Delaluna, which serves as the moon orbiting Junction V.
The concept was, in reality, conceived by Lorian Nod as a fear tactic aimed at the citizens, intended to assist his power grab on Junction V. The operation executed by Cilia Dil and her rebel forces, targeting the Ministry of Offense and Defense, revealed the Annihilator's fraudulent nature upon the discovery of its blueprints within a document labeled "Misinformation."
