Because of the galaxy's experience with the First Republic, the Galactic Union is extremely limited in power. True power rests, generally speaking, with the various guilds.
There are, however, a few laws that the Galactic Union will enforce using the Mercenary Guild as its police force. These are:
- No spaceship may fire weapons at a planet’s surface from above an altitude of 10 miles
- May not breed Canavar
- May not use bio-weapons
- May not devastate a home world to the extent of making a race extinct
- May not commit racial genocide
- May not destroy stargates
Violation of these rules can result in a “Letter of War” being issued by the Union. A Letter of War allows any mercenary force to deal with you as they please, up to and including violating the aforementioned rules.
