In 2376, the Delta Flyer was damaged by an encounter with a dark matter lifeform while exploring a class T cluster. Captain Kathryn Janeway took the Flyer to the radiogenic rings of a T-class gas giant to restart the warp core, but the Flyer was threatened by more lifeforms. Thus, Janeway ordered Crewmen Tal Celes, Mortimer Harren, and William Telfer to abandon the Flyer in escape pods while she provided a distraction.
