Star Trek: Deep Space Nine
Episode: DS9 426 - Melora

Planet: name unspecified. A space-faring humanoid people of a low-gravity world; only a handful have ventured off-planet, requiring the use of anti-grav wheelchairs whenever they leave. They have some relationship with the United Federation of Planets, since Ensign Melora Pazlar is the first native to be in Starfleet. They are familiar with mass transit concepts, including the old Terran "trolley car". They are not to be confused with the Elasians of the Tellun system in the United Federation of Planets-Klingon border area.
