The pursuit of Cassian Jeron Andor transpired in 5 BBY. This manhunt was orchestrated by ISB Supervisor Dedra Meero, seeking to apprehend Andor for his involvement in the ambush on Ferrix and his connections to the rebel Axis.
Upon her arrival, Meero established an operational headquarters within Ferrix's central urban area. Prior to this, Dedra Meero had interrogated former Preox-Morlana Deputy Inspector Syril Karn, hoping to extract intelligence pertaining to Andor's whereabouts and activities. Unbeknownst to the Imperial forces at the outset, Andor was already imprisoned under an assumed identity on the lunar facility Narkina 5.
