Devro was a Human male who served in the Bajoran Militia in the 24th century. In 2376 he held the rank of corporal and in April was newly assigned to security on Deep Space 9. In that month he awoke Kira Nerys to inform her of a fatality on the station. Shortly after he was assigned to watch over the Jem'Hadar Kitana'klan, being held in one of DS9's cargo bays. Later, while still on guard at the cargo bay Devro was killed, along with sergeant Cryan, when the Jem'Hadar made a successful escape attempt. (DS9 novels: Avatar, Book One, Avatar, Book Two)
