Gint

Gint was the first Ferengi Grand Nagus. Ten thousand years ago, Gint was the original author of the first aphorisms that would become the Ferengi Rules of Acquisition.

In 2372, Quark dreamed that he met Gint at the doorway to the Divine Treasury, where Gint told him that his life was more important than fulfilling a contract. Gint argued that the Rules were actually supposed to be nothing more than guideposts. (When asked why he decided to call them "Rules", Gint countered, "Would you buy a book called Suggestions for Acquisition?")

Strangely, Gint looked a lot like Quark's brother Rom. (DS9: "Body Parts")

Grand Nagus Gint was played by actor Max Grodénchik, in an effort to intentionally be resembling his character of Rom.
