During character customization, players must choose from one of three Alliances; the Aldmeri Dominion, the Daggerfall Covenant, and the Ebonheart Pact. Players are able to join various Guilds, regardless of their Alliance, and these include the Mages Guild, the Fighters Guild, and the Undaunted. The Thieves Guild and Dark Brotherhood will be added in-game post-launch. Other factions offer quests, but cannot be joined, such as the Great Houses of Morrowind. Many factions can only be interacted with in particular regions, for example the Maulborn in Deshaan, the Bloodthorn Cult in Glenumbra, or the Veiled Heritance in Auridon and other Aldmeri Dominion regions, however, players are able to experience another Alliance's content when they reach level 50, via Veteran Levels.
The Mages Guild appear in The Elder Scrolls Online. One way to increase reputation with this faction is to search Tamriel for hidden Lore books. Sufficient reputation increase will unlock additional skills, perks and abilities.
The Fighters Guild is a joinable faction in this game. One way to increase reputation in this guild is to destroy Dark Anchors of Molag Bal. With enough reputation, new skills and abilities will be unlocked.
The Undaunted is a guild involved in dungeons, and has its own unique skill line.
The Thieves Guild is dedicated to the gathering and training of those who are stealthy and shadowy in nature. Although criminal by its very definition, for untold years, local authorities in places throughout Tamriel have tolerated the existence of the guild for its role as "Crime Regulator".
The Dark Brotherhood is a guild of professional assassins which historically possessed considerable influence and power but has recently fallen on considerably harder times.
