The Secession Movement is a incredibly large, yet utterly disorganized movement unofficially founded in support of the Secession Party: a minority political party with little representation in the UN Council pushing for independence among UN colonies. The Movement and Party alike have a incredibly large following on Avalon.
While perhaps founded with noble intentions, the party has been linked to terrorist movements across United Nations Space claiming to represent the Movement. The Secession Party officially renounces these terrorist cells, but private investigations have produced evidence that there may be a conspiracy at hand.
The United Nations is yet to put out an official statement or prosecute the party for this supposed conspiracy, though many have demanded the governing body take action in response to the kidnapping and torture of UN Marine Skylar Wesley.
