The Dramen star system was an planetary system with at least two planets, inhabited by the Dramen, a spacefaring humanoid species. A remote system, Starfleet ships visiting it were out of communications range with the Federation.
In 2270, this system was visited by the USS Enterprise, where the system was noted to be located beyond the range of subspace communications with Starfleet. While investigating the system, Spock noted that "the historical records of this solar system are spotty, at best, going back 19 years. Mostly, they're technical data, meteor showers, auroras, radiation reports." (TAS: "Albatross")
