most sectors are controlled by one x-universe race, and will contain only stations economically indigenous to that race. for example, "atreus clouds" is a boron sector, containing only boron stations. here the player can buy special boron weaponry and equipment that is unavailable from other races. boron stations sell boron trade products, and they often want to buy the trade products of other races. such products can be imported, exported and traded by the player for profit. this compels the player to explore the sectors of the different races to discover the most useful upgrades, and most profitable trade routes.
