Ratav was a Cardassian man and a Glinn in the Cardassian military. He commanded a naval base near Tilar.
In 2348, Damar asked Glinn Ratav for help in locating Veja Ketan and Natima Lang. Ratav was both unwilling and unable to help as his fighters had been disabled by the Bajoran Resistance and needed to be repaired. (TLE - Terok Nor novel: Night of the Wolves)
