Trivia

 * Orcus was a god of the underworld, punisher of broken oaths in Italic and Roman mythology. As with his Greek counterpart, Hades, the name of the god was also used for the underworld itself. In the later tradition, he was conflated with Dis Pater.
 * His surname is a reference to Cocytus (/koʊˈsaɪtəs/, or Kokytos /koʊˈkaɪtəs/ (Ancient Greek: Κωκυτός, literally "lamentation"), the river of wailing in the underworld in Greek mythology. Cocytus flows into the river Acheron, on the other side of which lies Hades, the underworld, the mythological abode of the dead. His titles of Ice Daemon and Frost Lord, and his cold-based powers, are also references to Cocytus, but more specifically the Cocytus mentioned in Dante's Inferno, as well as the character Cocytus from the light novel series Overlord, of which the creator is a fan of.
