Kayron in 2364.
Kayron was a Ferengi who served under Daimon Taar in 2364. Along with the rest of the crew he participated in the theft of a T-9 energy converter from Gamma Tauri IV.
Following that incident Kayron was part of the Ferengi landing party that beamed down to a planet in the Delphi Ardu system when their starship was immobilized above the planet by a powerful force field. (TNG: "The Last Outpost")
