Fleet Admiral Allison Reyes is the director of the Advanced Science, Technology and Research Activity (ASTRA), operating from the USS Polaris, a mobile platform that serves the Fourth Fleet's needs along the frontiers of Federation space. With a decorated history in intelligence, engineering, R&D and command, she also serves as a senior representative of Starfleet and the Federation as it returns to the great unknown. Most recently, Reyes played an instrumental part in a corruption purge in 2398, and before that, she served as a member of the Fourth Fleet Command Council, as Fleet Executive Officer for the Fourth Fleet, and as Director of Fleet Research & Development.

Captain Gérard Devreux is the Executive Officer of the USS Polaris. Devreux has a long career of deep space expeditions and a spirit of exploration, stranded for seven years as a CO on the far side of a wormhole and having served as XO for one of Starfleet's few deep space exploration missions during the late 2390s. Following the launch of the Osiris Initiative, he was a natural choice to serve alongside Fleet Admiral Allison Reyes aboard the flagship USS Polaris as the Fourth Fleet returned, en masse, to the frontier with the launch of the Osiris Initiative.

Commander Jake Lewis is Chief Intelligence Officer of the USS Polaris. A pragmatist willing to bend the ideals of the Federation in order to protect them, Lewis is no stranger to controversy. In 2389, shortly after the break apart of the Romulan Empire, Commander Lewis was implicated in the assassination of dignitaries from several Romulan factions during a conference on Algorab. While granted a judgement of acquittal due to a lack of evidence, he was forced into retirement. For most of the 2390s, Lewis ran a private intelligence contractor, until, after supporting an investigation that uprooted a conspiracy in the Fourth Fleet, Lewis was welcomed back, with many skeptical onlookers, as part of the Osiris Initiative.

Commander Luke Lockwood, Ph.D. is the current Chief Science Officer of the USS Polaris. A former endowed chair in astrophysics at the Daystrom Institute, Lockwood was unexpectedly stranded in the Delta Quadrant when the Borg attacked Starbase 900, where he'd been giving a master class on superluminal transit. With his way home cut off, the professor turned refugee reluctantly accepted a commission with Task Force 38 searching for new ways to communicate with or return home. By the time they'd found their way home, he'd found his footing as a Starfleet officer and decided to continue his tenure with Starfleet.

Commander Henderson has dedicated himself to a life of research and service as a doctor specializing in interspecies medicine, a well-published exobiologist and a leading researcher in the field of interstellar epidemiology. Hardly an officer in the traditional sense, Henderson's lack of skill with a phaser is made up for in his other qualities, qualities that most recently landed him aboard the USS Polaris as head of medical and biological sciences within the Advanced Science, Technology and Research Activity.

Lieutenant Lisa Hall, Ph.D. is the Chief Counselor aboard the USS Polaris. Given the ship's role on the frontier, beyond the psychological well-being of the ship's crew out on the frontier, she also advises on psychological profiles, negotiations, interrogations and psychiatry. Before joining Starfleet, Hall worked as a private contractor, with three of her largest clients being Starfleet Intelligence, the Fenris Rangers, and the Romulan Free State. While Hall's education qualifies her as a counselor, her background makes her particularly suited for her current assignment.

Lieutenant Balan is an intelligence and cultural affairs officer attached to the USS Polaris. With a background in frontier space, strong empathic abilities, and a knack for alien cultures, she supports the Polaris' mission of exploration, helping the crew navigate interactions with alien species as they travel through unknown territory, engage in first contact, and visit strange alien worlds.

Senior Chief Shafir is an intelligence specialist in data systems stationed aboard the USS Polaris. A gifted hacker in a former life, she was recruited into Starfleet Intelligence as a field operator for her ability to extract data from any system even under the most high pressure circumstances. After a ten year hiatus following a year-long undercover assignment that caused severe psychological trauma, she's returned to Starfleet to serve on the USS Polaris in an intelligence unit tasked with a mix of external intelligence, internal investigations, and counterintelligence.

Commander Drake is the Chief JAG Officer stationed aboard the USS Polaris. A former regional JAG with borderlands experience, and a high profile prosecutor in the Admiralty corruption cases of 2399, Drake now oversees investigations and prosecution of sensitive JAG cases out on the frontier of Federation space. A zealot of Federation idealism, he's known for his willingness to attack any officer he perceives as having violated the law, and he takes great pride in the fact that his work has stripped dozens of their ranks and honors.
