In 2364, Jason Athelstan served aboard the USS Saratoga (NCC-31911) as an engineering officer. When the Saratoga rescued the USS Artemis survivors, he met Daniel Radke. (Star Trek: The Prospect Chronicles: "Lady Lazarus")
In early 2367, he and Radke served on Earth and helped keep the peace on Chicago's streets during the confrontation between the Borg cube and the USS Enterprise-D in the planet's orbit. Hours after the cube's self-destruction, Athelstan and Radke joined the rescue team aboard the USS Worsaae, under Anne Lansing's command, to help find survivors from the Battle of Wolf 359, including being a part of the away team to rescue a few survivors aboard the USS Princeton, using his engineering expertise to use a fire suppression system to provide a stable forcefield over a ruptured EPS conduit, allowing the team's escape. (Star Trek: The Prospect Chronicles: "The Burnt Child")
During that same year, he warned Radke, to be careful aboard the Artemis. After Radke's ordeal at the hands of the M'Tar, transformed into the Liaison, Athelstan pleaded with Prospect chief medical officer Justin O'Donovan to let him see Radke, which the doctor finally did. He stayed by Radke's side in Sickbay, assuring him everything would be okay and that he was there for him. (Star Trek: The Prospect Chronicles: "Lady Lazarus")
In 2371, Athelstan was offered the assistant chief engineer position aboard the USS Rutherford: an opportunity too good to miss. He left the Prospect-A that same year. (Star Trek: The Prospect Chronicles: "Home")
Later that year, the USS Rutherford went missing. The Prospect-A was sent to investigate and found the Rutherford but no crew, dead or alive. Starfleet assumed wherever the crew went, Jason Athelstan went with them (as no evidence to the contrary existed). (Star Trek: The Prospect Chronicles: "Directive")
Radke and Athelstan undertook a long-term relationship, being together for seven years.
In late 2366 and early 2367, upon learning about the Borg threat while in Chicago on Earth, Athelstan and Radke cuddled on the couch one night while watching FNN reports about the Battle of Wolf 359 and Captain Jean-Luc Picard's transformation into Locutus. They also patrolled the streets together, and made a pact if one was assimilated by the Borg, the other would euthanize him.
He comforted Radke after the M'Tar transformed the latter into the Liaison, disfiguring him and emotionally scarring him. Athelstan stayed by his side in Sickbay after the Prospect recovered Radke. (Star Trek: The Prospect Chronicles: "Lady Lazarus")
Athelstan followed Radke on various postings as Radke held the higher rank; however, in 2371, when an opportunity for promotion came for Athelstan, instead of discussing the opportunity with Radke, he broke off the relationship instead, and left. (Star Trek: The Prospect Chronicles: "Home")
Jason's disappearance and presumed death aboard the Rutherford distressed Radke a great deal. (Star Trek: The Prospect Chronicles: "Directive");(Star Trek: The Cantabrian Expeditions: "Isolation", "An Innocent Time")
