Throughout the franchise’s history, Star Trek has hosted diverse alien species. One that has evolved throughout the franchise is the Ferengi, which were once meant to be the big villains for Star Trek: The Next Generation.
Governing Ferengi society are the 285 Rules of Acquisition, which ensure a fair business deal for all parties involved — or most parties, as Star Trek: Deep Space 9’s bartender Quark explains. While the rules are specifically designed for business practices, several of them also have applications in other life scenarios.
