Born in the late 23rd century, Zek was a particularly hard-working Ferengi. He would spend 85 years without taking any significant vacations. (DS9: "The Nagus") In 2369, he suddenly announced his new successor, Quark (rather than his son Krax), and apparently died soon after. It was discovered that this was only a ploy to test his son's worthiness for the position. However, Krax did not succeed as expected, and Zek postponed his retirement. (DS9: "The Nagus") In 2370, Zek attempted to open negotiations with the Dominion, and although he opened contact with the Karemma and the Dosi for tulaberry wine, he was unable to contact the Dominion.
