Ferengi

From the Memory Alpha Information Directorate, a side project of Memory Alpha.

The Ferengi are a space-faring humanoid species native to the planet Ferenginar. Ferengi civilization is built on the ideals of free enterprise, where all other goals are subjugated to the pursuit of profit. Some Ferengi were known to show compassion, such as Quark towards Terran slaves on Alliance-controlled Terok Nor.
