One of the playable races in Starfleet Command II: Empires at War and Starfleet Command II: Orion Pirates. The Lyrans are a race of warlike carnivores.
Their space is in the upper-western quadrant of the map, bordered by the territory of the Hydrans, Mirak, Klingons, and, depending on the exact time period, the Federation. They are enemies with all of their neighbors save the Klingons, who they are weakly allied with. They also dislike both the Gorn and ISC, but tolerate the Romulans, albeit somewhat grudgingly.
Their ships have very durable hulls but fairly mediocre shielding and are armed with phasers, Expanding Sphere Generators and disruptors. They are maneuverable, but not to the degree that Klingon or Romulan ships are. The ESG provides significant protection against enemy fighters and missiles, but is also a useful offensive weapon. When playing against the Lyrans, watch out for overrun tactics, as this is the most effective way to use the ESG. Keep at a distance, and wear them down.
