The FMS Wealth is a Ferengi starship of an unknown class. It is the personal transport vessel traditionally used by the Grand Nagus of the Ferengi Alliance.
The Wealth had been recently constructed by 2372. In that year, Grand Nagus Zek brought Wealth to Deep Space 9. Zek later took it into the Gamma Quadrant through the Bajoran wormhole and then back to Ferenginar. (DS9 novel: The 34th Rule)
In 2385, the Wealth brought Grand Nagus Rom, Leeta and Bena to the second Deep Space 9 station to attend the dedication ceremony. (ST - The Fall novel: Revelation and Dust)
