Jahson was a Deltan man and an assistant to the Deltan Prime Minister in the 2360s. Jahson was managing an underground command center on Delta IV at the time of the combined Borg/Cyberman invasion on stardate 45635.2, 2368. He reported on the progress of the invasion and urged the Prime Minister to evacuate when Borg and Cybermen transported into the facility. Jahson and other Deltan personnel stayed behind to hold off the invaders and cover her retreat. (TNG - Assimilation² comic: "Issue 1") Jahson was likely killed, assimilated into a Borg, or converted into a Cyberman.
