Inglatu

From Memory Alpha, the free Star Trek reference.

Inglatu was a male Dosi, who along with Zyree, represented his people during negotiations with the Ferengi, represented by Quark and Pel, in 2370. The Ferengi sought to purchase 100,000 vats of tulaberry wine; however, the Dosi were unable to supply such a large order. They therefore referred the Ferengi to the Karemma, another supplier of the beverage.

The Karemma were an important commercial member of the Dominion and, in fact, Zek knew that Inglatu would not be able to meet the order and used that fact to make contact with the Karemma. This would be the Alpha Quadrant's first dealing with the Dominion (DS9: "Rules of Acquisition")

Inglatu was played by Trek regular Brian Thompson.
