The Apostate, a starship, belonged to Nik Hepho, the bounty hunter. In the year 0 BBY, while Hepho sought followers of the Church of the Force within Jedha City on the moon Jedha, the ship remained in orbit. A droid intelligence controlled the vessel, awaiting communication from the hunter's long-range transmitter attached to his backpack.
Pablo Hidalgo initially referenced the Apostate in his reference book, Star Wars: Rogue One: The Ultimate Visual Guide, which was published in 2016.
