Maihar'du

Maihar'du is a Hupyrian and the personal servant of former Grand Nagus Zek. As such, Maihar'du is only permitted to talk to his master.

Maihar'du would assist Zek in the day-to-day runnings of the Ferengi Alliance in the Tower of Commerce. 

In 2369, Maihar'du accompanied Zek to Deep Space 9, where Zek was to name his successor. Maihar'du assisted Zwk in his plan to fake his death to see if Krax was a suitably person for the title. 

When Zek returned a year later, he had Maihar'du bring gifts to Kira Nerys. 

After Zek encountered the Prophets and revised the Rules of Acquisition, Maihar'du helped Quark and Rom kidnap Zek and bring him into the Bajoran wormhole where the Prophets restored him to his normal self. 

Maihar'du would accompany Zek and Ishka to DS9 when Zek was deposed as Nagus. 

The following year, Maihar'du and Zek transported over to the mirror universe to see if the Ferengi could make profit from it. They were captured by the Alliance, although Ezri Tigan helped them escape after Quark and Rom brought a cloaking device. 

Later that year, Maihar'du came to DS9 when Zek was naming his successor. He later joined Zek and Ishka in their retirement on Risa. A year later, he came with them to Ferenginar.
