There are five factions in the game, each connected with a different Social Group:
- Aviary (Outlaws)
- Couriers (Distressed)
- Knights Errant (Travellers)
- Gildebones (Townsfolk)
- Seers (Nobles)
Once you have unlocked all Social Groups, and have over 50% reputation with one of them, members of the related faction will start appearing in your inn. You can rent them Private rooms. This in turn lets you send them on Quests.
