Gabriel "Gabe" Hwang was the estranged son of Raffi Musiker. He was born on Hellas Planitia on Mars in 2374, stardate 51554. A year later, on stardate 52461, he was vaccinated against three known diseases, namely typhoid, tetanus and the Andorian flu. Later in life, he was assigned Federation Security Number 0593-493-293.
By 2399, Gabriel resided in Stardust City on Freecloud. He was employed at Freebank and was married to Pel, who was pregnant with their daughter. In 2399, Musiker attempted to reconcile with Gabriel, who told her that he and his father were driven away by her "conspiracy theories" about the attack on Mars and resulting synth ban.
