Captain  was the commanding officer of the .

Bennington Biraka

Commander  was a Human Starfleet officer who served as the ship's counselor on board the USS Righteous. He apparently was a champion horse-jumper.

Qaylan Furlong
 was a Starfleet cadet who was born in 2358. His father, Ralph Furlong, was killed at the Battle of Wolf 359. Ten years later, with another conflict against the Borg looming, Q offered Qaylan a chance to go back in time and inhabit the body of a Bijani tactical officer named Sprint and attempt to save his father.

Ralph Furlong

Lieutenant  was a Human Starfleet officer who served as the flight control officer on board the Righteous. In the original timeline, at Wolf 359, Ralph Furlong was engaged in battle with the Borg with his fellow crew and was killed by them. 

Thaddeus Quint

Doctor  was the chief medical officer on board the Righteous. Q found he liked Quint's sarcastic personality, and assumed his role in history, with only the player being able to see that it was actually Q. In his role as Quint, Q saved Sprint allowing history to be changed by the player/Sprint and provides advice, including giving Sprint a medkit that allows him to resist assimilation by putting himself in a Bijani Pain Trance. Q as Quint shows a sense of doom in regards to the upcoming Battle of Wolf 359, which apparently matches Quint's own personality. After time is reset, Q reveals himself and restores Quint who neither knows, nor wishes to know, what has happened.

When Q gave Qaylan the opportunity to save the ship and crew, he had the cadet assume his identity. Once the Righteous was spared from its destruction at Wolf 359, Q did not bring back Sprint, stating that he was destined to die. Sprint was friends with Targus and Furlong in their days at the academy.
