Aeturnus is one of the officers who served with Praepositus in the human army opposing the Daedra. After the defeat he, unlike Praepositus, managed to regroup with other survivors and to rebuild a community (see Aeturnus' army). He stayed with the army up to just before the cloning machine had been finished. He had left to track down Praepositus for being a traitor, serving Uterio was too much of an insult to bare. He and a crack squad boarded onto the army's ship and set towards a forest which Praepositus had entered.
