Able Nereno was a Rodian male who served in the Alliance to Restore the Republic, with the rank of private. He worked as a nurse aboard the EF76 Nebulon-B escort frigate Redemption during the Battle of Endor. While he was treating a patient, one of the ship's oxygen converters exploded near his post. Nereno's patient lived, but the Rodian nurse did not survive the explosion.
Twenty days after the battle, Princess Leia Organa, a leading member of the Alliance, took time to personally notify Nereno's wife.
