Orcus – The Keeper of Oaths and Consequence
Interpretive Basis
Mythic Root:
Roman – Orcus was a god of the underworld, distinct from Pluto, who specifically punished those who broke their oaths. He ruled over the souls who violated promises, enforcing sacred contracts even after death.
Core Function:
Orcus governs oathkeeping, moral backbone, and karmic accountability. He reflects the gravity of one’s word and the consequences of betraying it — especially unspoken or soul-level agreements.
Astrological Role:
In charts, Orcus highlights themes of duty, integrity, and hidden vows. He reveals where internal laws are written — and where breaking them carries spiritual weight.

Elements are osculating heliocentric values from the JPL Small-Body Database (epoch per SBDB, queried 2026-11-06). For very distant bodies (e.g., Sedna) the barycentric period differs noticeably from the osculating heliocentric one.
Check against this note’s Orbital Signature: stated ~247 years; JPL gives 247.10 years.
