There are countless types of vessels within occupied space. Each Free World's government has specific designs that cater to their society and level of technology. Outer worlds possess faster than light technology that had been harvested through dig sites across their fifty planets, though their level of advancement is behind the Free Worlds of Humanity. Specific rogue world societies have advanced ships that were either stolen, retrofitted or piecemealed together using anything available. Freighters and civilian vessels remain in operation for generations, and it's a wonder how more haven't broken apart during long hauls in FTL travel.
