The Old Gods are a pantheon of dark and bloodthirsty deities which belong to ancient beliefs predating Christianity, presumably dating as far back to before the fall of Rome; Scáthach, a descendant of the Druids and their Roman conquerors, worshipped them long before the existence of the English Colonies in the New World and the United States of America. The Old Gods possess great and terrible powers and imbue their followers with dark magic and immortality. In exchange for the blood sacrifices of humans and animals, they grant or enhance the fertility of the earth, turning barren plains into fertile fields, and encourage orchards to bare fruit and flowers to bloom, bringing good harvest and mild weather. The Dying Grass Moon in the month of October, also known as the Blood Moon, can be considered both a corporeal and symbolic representation of the old gods' presence.
These deities possess a wide range of powers:
- Immortality: Being gods, these beings do not age and are immune to all human weaknesses (including mortality and disease).
- Blessing and Revocation of Immortality: The Old Gods are capable of blessing and revoking someone with immortality, turning humans and witches into immortals (in exchange for annual sacrifices of humans and animals), as well as turning back.
- Power Granting: The Old Gods can grant their worshipers supernatural powers in exchange for worship and sacrifices.
