Ro Gale was the father of Ro Laren. He died in 2347 during a Cardassian interrogation. His daughter was forced to sit and watch as he was questioned and tortured to death, while begging for mercy. This ordeal was one of the reasons his daughter ran away. (TNG: "Ensign Ro", "Conundrum")
Gale played the belaklavion, and used his music to put Laren to sleep as a young girl. He told her that the instrument's song scared away monsters as she slept. When he died, Laren realized that even he couldn't keep all the monsters away.
