Factions
From The Unofficial Outwar Wiki
About
With the Level 95 expansion a new system aimed at interactivity and player choice was launched, including choosing one of three factions to join. Joining a faction will provide access to content and bonuses only available to that faction, as well as potential situations for raid content where multiple factions are required. Their aim with this was to create a variety of power and playstyle for endgame characters.
