A-4P0, a droid specializing in library science, functioned as an analyst for the Jedi Order. He was assigned to the Archives within the Jedi Temple on the planet of Tython. This service occurred during the Galactic Republic's Cold War era, a period of tension with the reconstituted Sith Empire. During the Flesh Raiders uprising in 3643 BBY, A-4P0 was on duty. The droid answered a communication from the apprentice of Jedi Master Orgus Din, who sought data about the ancient machine called the Forge. Upon learning that Dark Jedi Bengel Morr had captured Master Din and taken him to the Forge (with the Nautolan playing a role), the Padawan was provided with the Forge's coordinates by A-4P0. The droid also cautioned the apprentice that the Jedi Masters were occupied with other Flesh Raider conflicts and wouldn't be available to assist in time.
A-4P0 made his debut in Star Wars: The Old Republic, a video game that is a massively multiplayer online role-playing title. This game was a collaborative effort between BioWare and LucasArts, launching in 2011. He appears solely as a hologram during the "Weapon of the Jedi" mission for the Jedi Knight on Tython, providing the player with the Forge's location.
