Gaila

Gaila was a Ferengi weapons dealer who was successful enough to buy his own moon. Odo noted that he knew Gaila to be a more devious Ferengi than Quark, his cousin. 

Gaila began his career in the weapons business in 2333. 

In 2362, Quark loaned Gaila the latinum to start a munitions consortium, and in return, Gaila promised to buy Quark a ship if he became successful. Gaila finally appeared to honor his debt in 2372 when he sent Quark a Ferengi shuttle in 2372, which Quark designated Quark's Treasure. The shuttle was later found to have been been sabotaged in a failed attempt by Gaila to kill Quark. 

Later that year, Quark planned to use the money generated from the sale of his vacuum desiccated remains to pay back Gaila. After he learned he did not have Dorek Syndrome, Quark tried to rescind the debt payments. 

In 2373, Gaila and his business partner Hagath approached Quark to make use of his holosuites for use in their business endeavours. Though Gaila and Hagath had no qualms about selling weapons that would be used to kill millions of people, Quark began to have a crisis of conscience, particularly after learning the Regent of Palamar intended to buy biogenic weapons that would be used to kill millions of people.

Quark eventually double-crossed Gaila and Hagath by arranging for the Regent's enemy, General Nassuc to come to the station and "accidentally" run into them. Following the ensuing firefight, Gaila and Hagath fled the station with the Palamarian Freedom Brigade's purification squads in pursuit. 

Gaila managed to evade the purifcation squads but soon fell on hard times. In 2374, Gaila was arrested on Thalos VI for vagrancy. Initially swearing revenge against Quark, his vengeance soon gave way to greed after learning about an offer to earn latinum by joining Quark's team to rescue his mother Ishka, who had been captured by the Dominion.

Gaila insisted that he was "a weapons dealer, not a soldier" and proved to be all too right as he jeopardized the mission more than once. First, he nearly allowed Keevan, the Vorta prisoner to be exchanged for Ishka, to escape when he fell asleep while guarding him. Later, after discovering that Quark intended to keep most of the reward money for himself, Gaila attempted to shoot him but shot and killed Keevan instead.

Despite the daunting setback, the Ferengi managed to rescue Ishka and take Yelgrun, another Vorta, prisoner. 

Gaila was one of the people that Rom tried to contact several months later, but was unable to, due to a communications blackout on Ferenginar.
