Chrysalians

The Chrysalians are a spacefaring race native to the Alpha Quadrant. They are a neutral people who have been at peace for 10 generations and now are "uninvolved in all interstellar matters of consequence."

In 2366, they hired a human, Devinoni Ral, to handle their affairs in negotiation for the Barzan Wormhole. The Chrysalians felt they had the resources, technology and science to oversee a wormhole, and Ral was able to secure exclusive rights to the wormhole by manipulating the Caldonians, the Ferengi, and the Federation. Eventually, the wormhole was determined to be useless, and Ral expected the Chrysalians to be quite angry when he returned to report to them. (TNG: "The Price")
