The Twin Furies' name may be a reference to the Furies (Erinyes) of Greek mythology, whose origin story is articulated within Hesiod's Theogony. The Furies (of which there are canonically recognised to be three) emerged from an act of violence between two divine family members, taking the form of chthonic deities of vengeance - both against those who harm family members and also those who have sworn a false oath. This theme is closely reiterated in the story of Avaryss, the Unceasing and Nymora, the Vengeful, who seek vengeance upon Gregorovic and the other generals located within the Heart of Gielinor.
