Janice Pelar

Jack Keller was the commanding officer of the USS Horizon (NCC-91901) since 2383, he was formerly the starship's executive officer. (, 🇸🇹)

Childhood
Keller was born in Baltimore, Maryland in 2346. During his young age he was close friends with Kelly Saunders. They had a close bond, and at some point during high school they thought about changing their relationship to one more intimate. But in the end they both agreed it might ruin their friend ship.

Academy years
Keller and Saunders both applied for the Academy and were accepted together. During his academy years he met and dated Janice Pelar, a junior cadet from Betazed. They were both leading towards majors and careers in science. Pelar broke off their relationship when Keller's career plans shifted to that of command. One of Keller's favorite instructors was then Commander Victor Mandrake, who went on to become Captain of the USS Vulture (NCC-14330) during the Dominion War. In 2380, Mandrake attempted to takeover the USS Pioneer (NCC-1084) from Captain Benjamin Kelsoe and his crew. He was unsuccessful and was court martial. This was heartbreaking to Keller, who had idealized Mandrake. ("Jump", "Mandrake's Stand")

Starfleet years
Between 2377 and 2382, Keller had served as the executive officer of the USS Dallas (NCC-2019). ("Dawn")

Assigned to Horizon Project
In 2383, Keller was reassigned to the Horizon Project under Admiral Thadius Rutledge. Keller had been selected to serve as the executive officer of the prototype ship for the new fold space drive. He was unprepared for the offer and the sight of his former lover, Janice Pelar, as a member of the crew. ("Jump")

Stranded
The jump test was successful, however upon entering their desired destination, the Dallos Cluster, the USS Horizon (NCC-91901) encountered a force of Breen ships advancing. They came under fire, and the captain and most of the bridge crew were killed. Only Keller and the helmsman, Ensign Manny Hakim, survived the initial attacks. Keller ordered a jump at only stage one power charge, causing the ship's systems to overload and the jump drive to transport them to random coordinates. As a result the ship became lost, with no navigation system to reenter the coordinates for the Oralian sector and Deep Space Five. Keller was blamed for the crew's predicament, but Admiral Rutledge held firmed and gave him command of the Horizon, ordering everyone to get behind and support Keller. After it was agreed he should take command, Keller and Pelar reconciled, deciding to give their relationship another go. ("Jump")
