A species of arms dealers to whom Quark introduced the Vulcan Sakonna in 2370, and who sold the Maquis disruptors, photon torpedoes and other heavy weapons.
The Pygorians are a species mentioned in the Deep Space Nine two-part story The Maquis. They are not seen on screen, but their willingness to sell heavy armaments has a direct effect on events in the Demilitarised Zone.
The Vulcan Sakonna comes to Quark with a shopping list of weapons on behalf of the Maquis. Quark, acting as broker, puts her in touch with the Pygorians, who provide ship-mounted high-energy disruptors, particle accelerators, two hundred photon torpedoes and a dozen pulse cannons.
Once Quark is arrested, he gives Sisko the details of the sale. Knowing how well armed the Maquis now are helps Sisko to work out that they intend to destroy a hidden Cardassian weapons depot.
