A sufferer from the Teplan blight in the Gamma Quadrant who volunteers for Julian Bashir's attempted cure in 2372 and dies when the treatment goes wrong.
Epran appears in the fourth-season Deep Space Nine episode The Quickening. He lives on a world whose people were infected by the Jem'Hadar, generations ago, with a disease that marks everyone from birth and one day quickens, bringing an agonising death.
When Bashir sets up a clinic and asks for volunteers in whom the blight has already quickened, Epran is among those who come forward. For a short time the doctor's antigen seems to be working.
Then the patients worsen: the electromagnetic fields of Bashir's instruments are causing the virus to mutate faster. Epran dies in great pain with the others, and the survivors turn to Trevean for a merciful end, leaving Bashir to face his own overconfidence.
