Ghost

A Ghost is a levitating artificial intelligence used by Guardians. The Ghost is the Guardian's flying companion, accompanying the player everywhere and being capable of accessing Golden Age technology. The Ghost also has a NAV mode which will locate beacons and receive missions from the Tower.

According to Grimoire Cards, Ghosts seek out their Guardian companions from the ancient dead, though it is unknown how these individuals are revived. The cards also state that Ghosts originate from the Traveler's technology and its light, indicating that these machines come from the Traveler itself.

Dead Ghost Locations
There are a number of dead Ghosts which can be found in various locations throughout the game. Upon finding one of them, the player can revive it, providing a small XP reward, instantly filling the player's Super Ability meter, and increasing the player's Grimoire score.
