In 2370, Zyree was involved in commodities trading, of products such as tulaberry wine. She discussed with Quark an offer to buy 100,000 vats of the wine from her associate Inglatu, but cautioned him that the only traders with that amount were affiliated with the Dominion, a dangerous power the Ferengi had never encountered. (DS9: "Rules of Acquisition")
Zyree was played by actress Emilia Crow.
Crow was chosen for the role partly due to her "buff" appearance. (Star Trek: Deep Space Nine Companion (p. 97))
Zyree was the first character in the Star Trek franchise to ever mention the Dominion.
