The Orion Freedom League was a small Orion political dissident group active on the Orion Colony of B'Morgia in the late 23rd century.
The League wanted to kick out all alien 'invaders' and re-establish the Orion 'Golden Age' of free trade and Orion piracy. It was particularly vocal about its views. King Holencas the Just tolerated their presence, just as he did a number of other dissident factions. (FASA RPG - The Orions module: Book of Common Knowledge)
- By the context of Orion history, the 'invaders' likely refers to the Federation. They have similar attitudes to Merkos Kerav of Daros IV, and a similar name to the Orion Victory League.
