Interactive hologram
An interactive hologram resembling Avar Kriss
Gatekeepers, otherwise called interactive holograms, served as a form of artificial intelligence that allowed individuals to gain access to the data stored within a holocron. These holograms commonly took the visual appearance of the individual who initially recorded the information. For instance, a holocron that eventually came into the possession of Luke Skywalker featured an interactive hologram modeled after Avar Kriss, who was a Jedi Master during the High Republic Era. When Hennix, one of Skywalker's students, activated the holocron, the interactive hologram greeted him and proposed to assist him on his journey.
