Star Wars: Pandora's Legacy
The Gatekeeper program’s holographic avatar appears as a tall, slender, androgynous figure, dressed as an Alderaanian noble.
Gatekeeper is the primary interface system for the exceedingly sophisticated ship’s computer system of the Second Chance. The system itself has an outlandish data storage capacity, although given the amount of Astrogation data necessary to work out the Pandora Equation, that is not entirely unexpected.
The computer has no direct control over ship’s navigation, but is tied into the general computing systems, including the navicomputer and the ship’s sublight drive transponder.
The nucleus of the system appears to be a hyper-intelligent droid-brain whose heuristic processors allow it to make subjective determinations about when to share information with authorized users.
