Perovius was a Human male who served Baron Peyar Cortess of the House Cortess, serving as his guard captain. When Peyar condemned his wife Chay Cortess for treachery, he ordered Perovius to kill her. Soon after, Cipher Nine and Vector Hyllus broke into Peyar's throne room. Peyar begged for the Imperial agents to spare his House from the Killiks. However, Cipher Nine killed Peyar and then killed Perovius before allowing the Killiks to attack.
