The events of the Ziost mission transpired amidst the backdrop of the Galactic War as a component of Operation End Game. Jedi Master Gnost-Dural and SIS agent Theron Shan executed a theft of a Black cipher from Davidge, the Imperial Minister of Logistics, with the objective of undermining and ultimately destroying the Ascendant Spear. By simulating a terrorist hit, they successfully swapped the operational cipher for a broken one, subsequently fleeing back to Coruscant in possession of the functional cipher. Subsequently, they leveraged this cipher to monitor the Ascendant Spear's trajectory.
