Project: OUROBOROS is an ever changing contingency plan created by the Unified Earth Government in case human society collapses. The UNSC Infinity was completed in secret as a result of the project. Originally intended to be a mobile colony ship, the Infinity has since become the flagship of the UNSC Navy.[1]


  • The ouroboros is an ancient Egyptian symbol that is often associated with introspection and the cycle of life and death.[2]
