Funny, I wikied what Cartel (http://en.wikipedia.org/wiki/Cartel) means, kind ironic considering what actual Cartel environment is like. Perhaps planet originally had no name and when other culture found it then presentatives of the planet named the planet Cartel in honoring alliance between several corporations which already exchisted in planet (and several corporations created generation class startship what ancestors flied to this planet). Of course meaning of the name is joke to present era of Cartel, a memorial from better times of the past and overall planet has such feeling if someone studies it's history any lenght.
