Guardian

The Guardians are the player characters of Destiny. They are a standing army of specialized soldiers tasked with the defense of the last city on Earth. They are also responsible for exploring the remnants of human society abandoned throughout the solar system, what remains of their Golden Age of exploration. Guardians wage a vicious armed conflict against a myriad of extraterrestrial species who pose an immediate threat to the survival of humanity. The greatest source of the Guardian's power lies in their ability to harness the energy of The Traveler and use it as a weapon against their opponents.

When creating their character, players may choose to make their Guardian one of three species:
 * Human
 * Exo
 * Awoken

Species is a purely cosmetic choice for players, affecting only appearance and not gameplay. Player specialization and progression, including available focuses, abilities, weapons, and armor, are dependent on the player's choice of one of three player classes:
 * Hunter
 * Warlock
 * Titan

Any species may choose to be any player class.

Guardians also have access to a Ghost, a small, flying bot with artificial intelligence that can assist the Guardian in tactical situations.

Guardians are speculated to align themselves with Factions, though the nature and mechanics of how factions figure into gameplay are not yet known.

Trivia

 * Guardians were originally called "Knights" in early leaked materials. The reason for the name change is unknown, though it is noteworthy that the term "knight" now refers to a class of Hive.
