You don't have to read too much between the lines to assume that the inhabitants of Ecaz are the drug barons of the Duniverse.
So, in addition to being our trade faction I think we should be using the rich and varied planet life of Ecaz as part of their theme.
This sounds cool, I'll think about it.
For Corrino, as mentioned before, it would be interesting to give them some ability to incite or stop wars between other factions.
How about they get 2 votes in the Landsraad? And add some Over-council style declare-war-on-X motions.
