Final Assignment:	Communications officer, Columbia (NX-02)
Rank:	Ensign
Insignia:

Sidra Valerian was a Human female serving in Earth's Starfleet in the 22nd century. Valerian was of Scottish ancestry, and spoke with a Scottish accent.

In 2156, Valerian held the rank of Ensign and served as the senior communications officer aboard the Columbia.

Following an attack by the Romulans, the Columbia used its impulse engines to make a dangerous journey using time dilation, to reach the nearest class M planet.

Valerian was part of the landing party to the planet Erigol that made first contact with the Caeliar race. After efforts by other members of the the team to use the Caeliar's technology to return the Columbia to its original time went badly wrong, the city of Axion was relocated in time to the year 1519.

After being informed that there was no way to return to her own time, Valerian slowly became mentally unstable, requiring constant care from Johanna Metzger. She lost the capacity for speech and did not interact with most of her mates, only the doctor herself, and then only to be led around. After Caeliar engineer Edrin constructed a holographic program of a warm, sunny beach, Valerian was escorted there every day, and she frolicked, often without clothing; however, she remained mute outside of the holochamber. After Metzger committed suicide in 1573, Valerian's condition worsened considerably. She sank into a catatonic comatose state, where she ate nor drank, and her body began to destroy itself, a condition her former crewmates allowed to ravage her body for three days. Wishing to find a way to heal her friend, former Earth Starfleet Captain Erika Hernandez allowed Inyx of the Caeliar to perform an experimental procedure on her, attempting to infuse her with catoms and link her with the Caeliar communal gestalt, hoping to use the group mind to draw her out. The procedure failed when Valerian's mind rejected the link with the gestalt, and she died on the operating table while Hernandez and Veronica Fletcher looked on. (ST - Destiny novel: Mere Mortals)
