Melora Pazlar

Lieutenant Melora Pazlar was the first Elaysian to join Starfleet. A native of the null-gravity, artificial planet of Gemworld, Pazlar was forced to resort to utilizing a mobile, null-gravity chair and later a Lieber exoskeleton in order to work in normal gravity environments.

Starfleet
Residents of Melora's homeworld seldom leave their planet, as normal gravity is extremely uncomfortable for them. Melora was an exception who wanted to see the galaxy and decided to join Starfleet. She attended Starfleet Academy, and majored in stellar cartography.

Deep Space 9
In 2370, Melora was briefly stationed at starbase Deep Space 9 and became romantically involved with Doctor Julian Bashir. Bashir developed a treatment that would allow Melora to function normally in normal gravity, but Melora declined as it was irreversible. (DS9 episode: "Melora")

During the Dominion War, Melora was decorated for valor after helping to save 192 of her shipmates. (TTN novel: Taking Wing)

The Enterprise
Following the war in 2376, Pazlar was assigned to the USS Enterprise (NCC-1701-E), under the command of Captain Jean-Luc Picard, for a scientific study of the effect of low-gravity on planet Primus IV.

Before arriving at Primus, Pazlar received a telepathic distress call from one of her worlds species, the Lipul, that indicated that Gemworld was in catastrophic danger.

Pazlar convinced Picard of the threat and upon arrival at Gemworld, the Enterprise discovered that the machinery that maintained Gemworld's atmosphere was failing. Pazlar and the Enterprise crew managed to save the artificial world from destruction, but Melora was forced to take the life of one of her people. ( books one and two)

Melora took an extended leave from Starfleet and performed her peoples attonement rituals, despite her worlds Exalted Ones finding her innocent of murder, her actions deemed unavoidable. (TTN novel: Taking Wing)

While serving on the Enterprise, Melora was briefly romantically involved with shipmate Reginald Barclay. (TNG novels: Gemworld)

USS Titan
Pazlar returned to Starfleet in the year 2379, serving briefly on the science-vessel USS Aegrippos before accepting Captain William T. Riker's offer to serve on the new USS Titan (NCC-80102) as the head of stellar cartography department. (TTN novel: Taking Wing)

Shortly after Titan began her exploratory mission of the Gum Nebula in early 2380, Pazlar was visciously attacked by her shipmate Tuvok, who was under the telepathic control of the star-jellies. Shortly after the incident, Melora asked Tuvok to train her in various means of self-defense. (TTN novel Orion's Hounds)
