Ghost

The Ghost construct.

A Ghost is a piece of equipment issued to each Guardian.^[1]

Overview

Appearing as a small, floating drone,^[2] 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.^[3] 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.^[2]

Trivia

The Ghosts are voiced by Peter Dinklage. ^[4]
It was indicated pre-release that players need certain equipment before having access to a Ghost.^[5] This is currently not the case, as the Ghost is present with the player from the start of the game in current builds (having revived them).^[6]
Ghosts may be deactivated and revived.^[7]
The Ghost's saying "We always visit such cheerful places" is a possible reference to Cortana's line in Halo 2 on the level Delta Halo, saying: "We always visit such nice places".
Dead Ghosts can be found in the game world which, upon revival, unlocks a new Grimoire card.
According to an advertisment for Destiny, Ghosts existed during the Golden Age.^[8] This is likely an error as all other sources have stated that Ghosts were created by the Traveler after the Golden Age.
