- The Ouroboros Dragon was released on July 18, 2013.
- The Ouroboros Dragon's breeding and incubation times of 26 hours 24 minutes when converted to 1584 minutes is likely a reference to Jacopo Brocardo, an Italian biblical event interpreter that wrote commentary on the apocalypse. He believed 1584 would be the beginning of a new cycle, and spent many years writing about the biblical apocalypse in correlation to life in late 1500s France.
- Ouroboros (Greek: Ουροβόρος, from ουροβόρος όφις “tail-devouring snake”) is an ancient symbol of a serpent or a dragon swallowing its own tail and forming a circle.
