Tribe

From Galactic Fleets Wiki

There are four tribes that are at war with each other. You choose which tribe you want to be in when you first sign up. The four tribes are called Altian, Casian, Raxian, and Solian. You can only trade in your tribe. You also have to be in a faction thats the same tribe as you. You have no way to trade or transfer your ships and planet to other tribes, although, you can still transfer points and credit.
