Atirias th'Qalren was an Andorian th'an serving as a Starfleet Officer during the 24th century.
By 2373 she held the rank of Lieutenant and was assigned to the USS Camelot as the heavy cruiser's Structural Integrity Division Officer.
During Operation Return she was responsible for turning on the forcefields blocking access to the stardrive from the doomed saucer section.
When Fleet Captain Gedna Tachion took command of the Camelot and promoted Gallagher to XO, she was made Chief Engineer.
On stardate 51905.4, she went aboard the recently found USS Potemkin to assess the damage and prepare the aged Constitution class starship to leave the Styx Rift. (Perdition's Flames")
