A faction is a group of individuals, such as a political party, contingent of vassals, a trade union, or other group united for a common purpose. All Factions have a leader, a number of members, and a clear goal (for example, to Lower Crown Authority in the Qahlaysae Sector).
A faction or political party may include fragmented sub-factions, “parties within a party," which may be referred to as power blocs, or voting blocs. Members of factions band together as a way of achieving these goals and advancing their agenda and position within an organization.
Factions are not limited to political parties; they can and frequently do form within any group that has some sort of political aim or purpose.
