Boda Jahlet was an exofemale Jelna native to Rigel V. In the mid-22nd century, Jahlet served as a diplomat for the Rigelian Trade Commission. (ENT - Rise of the Federation novel: Tower of Babel) After the admittance of Rigel to the United Federation of Planets, Jahlet became one of the Federation's leading Ambassadors. (ENT - Rise of the Federation novel: Live by the Code)
Jahlet had a craggy, marble-colored face adorned with horizontal green stripes. A pair of black lines arced from her hairline to the corners of her mouth, bisecting her eyes and outlining a darker-hued section on either side of her nose. Admiral Archer didn't know whether these markings were natural or tattooed. (ENT - Rise of the Federation novel: A Choice of Futures) She wore elaborate wooden beads in her hair.

In January 2155, Jahlet was one of two Jelna dignitaries participating in the conference on Earth that led to the founding of the Coalition of Planets. It was there that she met Captain Jonathan Archer for the first time. (ENT episodes: "Demons", "Terra Prime") However, the Rigelians didn't join when the Coalition was founded in March of the same year. (ENT novel: The Good That Men Do)
On March 13th, 2163, Trade Commission ambassador Boda Jahlet was one of the dignitaries participating in the Deneva Conference between the United Federation of Planets and non-aligned worlds to discuss a response to the Mute crisis. There, she met Admiral Archer again, whom she had approached to organize the conference in the first place. At the conference, Jahlet also met Admiral Shran and introduced the two admirals to the Xarantine representative Orav Penap.
On March 17th, Ambassador Jahlet invited Starfleet to set up their task force in the Beta Rigel system to help contain the escalating Mute attacks. Two days later, Starfleet assembled a taskforce at her native Rigel V. (ENT - Rise of the Federation novel: A Choice of Futures)
On June 18, she accompanied Director Sedra Hemnask of Rigel V to Babel to negotiate the admission of the Beta Rigel system to the Federation in the latest of the Babel Conferences. She listened to Captain Malcolm Reed's report about the crisis in the system. A Zami syndicate was threatening to release personal and state secrets. Jahlet explained to Archer how the Rigelian system of using secrets as leverage came about.
Jahlet and Hemnask were still on Babel Station by June 20th, when Admiral Archer tracked them down after an inflammatory speech by presidential candidate Anlenthoris ch'Vhendreni to apologize for Thoris's behavior. Jahlet accepted the apology. Later on, she was uneasy during an emotional discussion between planetary representatives during a conference of ambassadors. She explained that Federation law would cripple illicit activities in the Rigel system. (ENT - Rise of the Federation novel: Tower of Babel)
In 2165, now-Federation Ambassador Jahlet was assigned to the Starfleet Ware task force to assist in defending the crew of the USS Vol'Rala, who was charged with attempted genocide against the Partnership of Civilizations. (ENT - Rise of the Federation novel: Live by the Code)
