Structures Traders are what became of two resource-intensive professions, Architect and Shipwright. Structures traders are responsible for all player housing, all harvesting installations, all factories, and any civic structures such as cantinas, banks, and city/guild halls. Shipwrights, introduced into the game with the release of the Jump to Lightspeed expansion, are concerned solely with the crafting of starship components and chassis, as well as with the process of Reverse Engineering.
