Just some working ideas on new descriptions. I'm no writer but nonetheless I think it gets the point across that each description needs to start out positively, tread on some negatives, then return to some positives.

Amarr
The Amarr Empire is the oldest and largest of the four empires. Based strongly around their religion with their mighty Empress at the head, they believe it is their responsibility to unite all the people of New Eden. To achieve this, they search for primitive worlds and guide them as parents to modern education and standards of living. Part of this guidance involves hardships, which some brutally take too far. In the end, the captured race is welcomed as full citizens among the Amarr Empire. This mass unity of peoples has brought great stability to New Eden.

Minmatar
Once a tribal and primitive people, they were captured by the Amarr many years ago. They believed their parental guidance to be more of a slavery, and rebelled against their oppressors. Through foreign aid, they were able to break free of their bondage with the Amarr Empire and form their own Minmatar Republic. To this day, they still hold onto their tribal ways making them quite aggressive in diplomatic affairs. They have won their freedom against all odds and proudly carry forth their culture into these new days.

Gallente
The second largest of the four empires, the Gallente Federation represents the only true democracy of New Eden. As they took to the stars, they actively searched for all other signs of life and liberated them from their old ways, spreading the ideologies of freedom and individuality across New Eden. With such a large democracy, some corruption has taken root such leading to terrifying treatment of POWs and accepting civilians as collateral during war. Regardless, the Gallente Federation remains the last hope of democracy in New Eden.

Caldari
Caldari State is a capitalistic society run by a number of megacorporations. Once a member of Gallente Federation, the Caldari seceded as they believed the Federation was unfairly taking advantage of their fiscal gains and taking away their cultural identity. While a society run entirely by corporations presents a cold and harsh reality, their culture is founded around the ideals of honor and duty as well as their motto, "All For The Good Of Many."
