Mission 46/N
Mission 46/N was a survey mission undertaken by MB1711-V. The mission claimed to have found the Aldera Royal Palace still intact within the remains of the Graveyard, along with information that Bail Prestor Organa was alive and located within the ruins.
Behind the scenes
Since the information was planted in Mining Outpost 11's computers as part of a trap to ensnare the Heroes of Yavin, it is unclear whether or not Mission 46/N is a real survey mission or merely invented for the deception.
