Dosi

The Dosi are a humanoid species from the Gamma Quadrant. They are not members of the Dominion, although they have had business dealings with the Karemma. Prior to 2370, they knew very little about the Dominion itself.

In 2370, Grand Nagus Zek had Quark open negotiations with the Dosi for tulaberries, although Zek's real goal was to get the name of a contact in the Dominion so the Ferengi could open business negotiations with them. Quark and Pel negotiated with them on Deep Space 9 and later on the Dosi homeworld. 

Feg and Triv, two Ferengi businessmen, ventured into the Gamma Quadrant after Quark's negotiations with the Dosi. 

By 2372, Quark owed the Dosi money. When he found out he was dying in that year, he was not concerned with paying them back before he died. 

Zin Dezavrim, captain of the Even Odds, had several Dosi birth-rite masks in his quarters aboard the ship.
