The Chrysalians were a spacefaring race native to the Alpha Quadrant. They were a neutral people who, as of the mid-2360s, had been at peace for ten generations and who were "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")
