Almost all NPCs and creatures in Skyrim belong to one or more factions (or guilds). These faction memberships control the combat reaction of all NPCs and creatures, both towards you and towards one another. You can be a member of more than one faction at a time.
There are four primary factions that you can join.
- Companions — A guild of mercenaries, dedicated to combat, based in Whiterun. They are similar to the Fighters Guild in previous games.
- The Circle — The most trusted and accomplished members of the Companions.
- College of Winterhold — A guild dedicated to the study and practice of magic and based in Winterhold. They are similar to the Mages Guild of previous games.
- Thieves Guild — A secret guild dedicated to professional thievery, based in Riften.
- Dark Brotherhood — A secret guild made up of professional assassins, the same as from previous games.
You may also take part in the civil war by joining one of these two factions.
- Imperial Legion — The military power of the empire, they seek to maintain Imperial control of Skyrim from their base in Solitude.
- Stormcloaks — The main organization of rebels in Skyrim's civil war, they seek Skyrim's independence from the Empire. They are based in Windhelm.
This joinable faction doesn't have its own lengthy quest chain.
- Bards College — A guild of musicians, vocalists, and story tellers, based in Solitude. They have a single quest to join and a few sidequests for members.
Two new factions become available with the Dawnguard add-on.
