Masked Breen

The "Masked Breen" was the name given to the first Breen to visit Ferenginar, sometime between the mid 20th and mid 22nd centuries. He was given this name by the Ferengi he encountered due to the spacesuit helmet he continuously wore (the Ferengi being unaware that no Breen ever removed their helmets in alien atmospheres). The Masked Breen was responsible for selling warp drive to the Ferengi, for which he charged the price of Ferenginar's North and South Poles, plus seven remote moons and six comets in the Ferenginar star system. 


 * The short story "A Dry Day on Ferenginar" says Ferengi warp technology was purchased from the Breen by DaiMon Greko, after he had left Ferenginar aboard a Ridorian merchant ship. It is unclear how these two stories might be reconciled.
