A Fallen Light, A New Hope
An Organization is a separate entity that is self funded, promoted and decides its own interests from a political party or lord or ruler of a given area.
An Organization can hold great power in a specific area if they have a high enough member base, high gold reserves and enough sway over the local area.
Many Organizations have powerful members to maintain their position in the land.
An Organization will have a base of operations (Or a Head Quarters), that is not located in a city, often a Fort or some type of fortified structure.
Player association with organizations
A player may not be automatically associated with an organization at level 0. A player character created further into the campaign may be an associate with an Organization at the approval of the GM.
