Background information

"gam-uh AIR-ih-don" was the pronunciation for this location's name from the script pronunciation guide for "Redemption II". [1]

According to Star Trek: Star Charts (p. 62) and Stellar Cartography: The Starfleet Reference Library ("Stellar Cartography", pp. 27, 30; "Federation Historical Highlights, 2161-2385"), Gamma Eridon was a binary star system with a pair of M-class stars. According to a map of the Klingon Empire – prepared by the Scribe K'Tark for the Klingon High Council in the Year of Kahless 893 (2266) – Gamma Eridon was identified as a Klingon system.


In the game Star Trek: Armada, the Gamma Eridon system is infested by the Borg, and Chancellor Martok launches an attack to destroy all enemy forces in the system.
