Orcus is the Roman Underworld god of eternal punishment and broken oaths.

The Heroes of Olympus

The Blood of Olympus

Orcus was mentioned by his descendent as the punisher of those who have broken their oaths.


  • Orcus presumably has the standard powers of agod.
  • Necromancy: Orcus can summon the souls of those who have broken oaths to his aid. His descendant Bryce Lawrence has the same ability though Orcus is more powerful as he's a god.


  • Orcus is a Roman god that has no Greek equivalent, though he is sometimes considered to be the Roman equivalent of Hades and Horkos.
  • His Norse equivalent is Odin.
