Cabal is the term used for guilds in The Secret World.
From Wikipedia, the free encyclopedia
A cabal is a group of people united in some close design together, usually to promote their private views and/or interests in a church, state, or other community, often by intrigue. Cabals are sometimes secret societies composed of a few designing persons, and at other times are manifestations of emergent behavior in society or governance on the part of a community of persons who have well established public affiliation or kinship. The term can also be used to refer to the designs of such persons or to the practical consequences of their emergent behavior, and also holds a general meaning of intrigue and conspiracy. The use of this term usually carries strong connotations of shadowy corners, back rooms and insidious influence; a cabal is more evil and selective than, say, a faction, which is simply selfish; because of this negative connotation, few organizations use the term to refer to themselves or their internal subdivisions. Amongst the exceptions is Discordianism, in which the term is used to refer to an identifiable group within the Discordian religion.
The term cabal derives from Kabbalah (a word that has numerous spelling variations), the mystical interpretation of the Hebrew scripture, and originally meant either an occult doctrine or a secret.
