Grand Nagus
The Grand Nagus was the leader of the Ferengi Alliance, and the financial leader of billions of Ferengi. () Virtually all decisions that affected the Alliance required the approval of the Grand Nagus, whose power was backed by the Ferengi Bill of Opportunities and supported by the Board of Liquidators. ()

The Nagus's offices were located in the Tower of Commerce on Ferenginar, where he presided over the Alliance from the Chamber of Opportunity. Petitioners regularly sought to speak to the Nagus to solicit advice on business ventures and decisions. In doing so, they were required to pay their respects, literally (in a slip of gold-pressed latinum). After doing so, their petition was summarized by the First Clerk before the Nagus reached a decision. ()  The FCA has the power to remove a Grand Nagus from office, though only in the rare circumstances that it is overwhelmingly obvious he has become medically or mentally unfit for the role (i.e. advancing senility). ()

While greed and selfishness were considered respected traits for Ferengi, the Grand Nagus was expected to think for the greed of the entire Ferengi Alliance, not just his own. ()

The Nagus resided in the Nagal Residence, which was said to contain latinum-plated fixtures. () The Nagus always carried a staff and it was traditional for the Ferengi to kiss it upon meeting him. (, et al)

The Grand Nagus possessed the ability to appoint a Grand Proxy to act in his name in matters which he was unable or unwilling to deal with personally. ()

A Nagus could also overrule the decisions of the Ferengi Commerce Authority if he so chose, such as in matters of business license revocation. ()  

Rom became Grand Nagus in late 2375, succeeding Zek. This came following a series of social reforms, among which was the introduction of the Congress of Economic Advisors, a new legislative body that limited the Nagus' power. ()
