An alien merchant who traded with Enterprise in 2152 and pointed Archer towards a crashed ship full of salvage, while warning that his own people believed the wreck to be haunted.
D'Marr appears at the start of the first-season Enterprise episode Oasis, played by the television presenter Tom Bergeron. He comes aboard to barter supplies and, over a meal with the senior officers, learns that the ship needs engineering materials.
He tells them of a vessel that came down on a barren planet years earlier and still holds useful components. D'Marr admits that he gave up on the salvage himself because his crew fled, swearing that the dead ship was haunted.
His tip leads Enterprise to the Kantare wreck, where the supposed ghosts turn out to be holograms created by the engineer Ezral to keep his daughter Liana company.
