Dorian Collins (Baldwin)

Ensign Dorian Collins was a Starfleet officer in the late 24th century.

Starfleet career
As a cadet at Starfleet Academy, her performance stood out among many of her peers, and she was invited to join the elite cadet group known as Red Squad. As a member of Red Squad, she was assigned to the USS Valiant (NCC-74210) for field training exercises when the Dominion War broke out and was attacked, resulting in the loss of all of the supervising instructors.

She was given a provisional rank of Chief Petty Officer by Cadet, who had assumed command of the ship. She served aboard the Valiant until acting Captain Watters went on a foolhardy pursuit of a Jem'Hadar Battleship. She was the only Red Squad cadet to survive. 

She was later returned to the academy, where she maintained excellent grades in her academic pursuits, but was falling behind on field work. One of her teachers, Admiral Belding, recommended her for additional field duties aboard the USS Baldwin (NCC-2013).

Richie would assign her to duties in the engineering department, where she was made comfortable and given positive encouragment by her fellow crew members, including her supervisor, Bridget, and the ship's XO, Jaimie Petrelli.

She would be an observer to the budding relationship between Baldwin Captain Richie Kennedy and her supervisor. She expressed concern for Bridget's helth when she was experiencing the early signs of pregnancy.

After three months aboard Baldwin, Richie invited her to stay on, which she accepted.

Background
