- "They've done more good than harm. By most calculations."
- —Grimoire description
Factions are groups that Guardians can join and earn Reputation with. Most factions are based within the Last City, but some are found elsewhere, such as the Reef. Completing activities for a faction allows Guardians to increase their rank with them and earn rewards. On the other hand, there are some factions that cannot be joined because they have no Reputation stat, and furthermore, the enemy races have their own factions dedicated to their own goals.
These three factions form the City's government, the Consensus, and seek champions among the Guardians to represent them in the Crucible. Guardians may pledge themselves to a faction for a fee of 2500 Glimmer to support it and earn faction-specific rewards, such as Weapons, Armor, Emblems, and Shaders. Guardians can only change their allegiance once per week, and must pay the fee each time. Players continue to earn Vanguard or Crucible Reputation in addition to Reputation with their faction.
If players earn Level 25 Reputation with a Faction, they'll unlock a Faction quest that rewards an Exotic Class item that increases Reputation gains with that Faction.
|Dead Orbit||Future War Cult||New Monarchy|
"The Traveler is not our only salvation. Another future lies out among the light of other stars."
Dead Orbit is a survivalist faction that believes humanity's future lies not on Earth with the Traveler, but in a great diaspora throughout the universe. They hope that by colonizing as many worlds beyond the Solar System as possible, humanity will become too innumerable for another disaster like the Collapse to break it or an enemy like the Darkness to extinguish it. Dead Orbit members are currently assembling a fleet of starships to begin their interstellar journey.
"There is no future but now. No truth but war."
Future War Cult is a fatalist faction that believes conflict is the quintessential nature of the universe and the inescapable end-state of most, if not all possible realities. Known for their martial prowess as much as their secrecy and eccentricity, Cultists assert that another confrontation with the Darkness, the "coming war", is inevitable whether humanity makes its stand on Earth or attempts to flee elsewhere. In their opinion, preparing for that confrontation should be the sole, driving purpose of the Last City and the Guardians.
"Hope will be born from the collective triumphs of the king in us all."
New Monarchy is a monarchist faction that believes humanity should strive to restore the lost glory and order of the Golden Age, and that the ideal way to achieve that is by uniting the Last City under a single, benevolent ruler invested with absolute authority. New Monarchists view the Consensus as a tenuous compromise that impedes the path to true progress. They patiently await the day when the Consensus voluntarily abolishes itself and a monarch is chosen by acclamation.
