Dahae was a female Human who lived during the late-24th century. During the early 2380s she served in the operations division aboard the USS Cerritos under Captain Carol Freeman.
In 2380, she held the rank of ensign, and was among the engineering crew present in main engineering when Sam Rutherford requested a transfer to another department. (LD: "Envoys")
She later ran through a corridor carrying a crate, following the implementation of the Temporal Edict and the boarding of the Cerritos by a boarding party of Gelrakians. (LD: "Temporal Edict")
She was in engineering when the Cerritos was conducted the towing mission of the ancient generation ship. (LD: "Moist Vessel")
Rutherford imagined her, along with the rest of the engineering staff, having their minds blown if he'd brought back a T88 from the USS Vancouver. (LD: "Cupid's Errant Arrow")
She was in engineering with Rutherford when Mariner called Rutherford from the USS Rubidoux for an emergency beam out. She then watched the emergence of a space vessel lifeform from the hull of the Rubidoux through a Cerritos viewing port. (LD: "Much Ado About Boimler")
On stardate 57791.1, she held the rank of commander, when she ran through the corridor past the repair bay when Tendi, Mariner, Rutherford, and Boimler discovered that the ship was on red alert. (LD: "Veritas")
Late that year, shortly after it was revealed that Beckett Mariner was the captain's daughter, she and a Bajoran engineer were in the corridor watching as Mariner walked by, before gossiping about the new revelation. A short time later she was in main engineering when the Freeman ordered the ship to power down after it captured by a Pakled Clumpship. Following the conflict, she attended Shaxs' funeral. (LD: "No Small Parts")
In 2381, she participated in the training drills presented by Shari yn Yem, wherein she undertook and failed the simulation Extreme Engineering. (LD: "I, Excretus")
She was later in the bar sitting with Arjun when Mariner told Jack Ransom, Shaxs, and Andy Billups about Captain Freeman's promotion to a new ship. (LD: "First First Contact")
In 2381, Dahae was present in the ship's bar sharing a cocktail with another officer, when Commander Random ordered a paper bag of churros to replenish those used for Churrolivia. (LD: "Room for Growth")
Dahae was identified by an onscreen display appearing in "I, Excretus".
