Ghost

A Ghost is a piece of equipment issued to each Guardian.

Overview
Appearing as a small, floating drone, Ghosts were created by the Traveler "with its dying breath", and have spent their time since the Collapse searching for their guardians. While Ghosts can revive their Guardian from death, Ghosts themselves are irreplaceable. The Ghost serves as a scout, librarian and mechanic, waking ancient machinery and cracking ancient codes. They seem to possess some degree of artificial intelligence, being able to converse with their masters in a very human manner.

Ghosts can support the player by performing certain actions such as illuminating darkened areas, repairing technology from the Golden Age, informing the player of incoming hostile threats, telling the player about new objectives, and serving as a marker beacon/respawn point when a player's character dies during cooperative play.
