Iron

Iron has been long known as the bane of the fae and malignant spirits since the earliest tales of the forge. The discovery of iron allowed humans to finally have a physical weapon capable of injuring the spirits who lurked in the darkness of night and the deep forest. Often seen as a symbol of humanity taming the wild earth - pulling a stone from the ground, and - with fire and forging - creating a new weapon against the unknown.

Whatever the reason, it is the bane of the fae. In Celtic lore, iron nails driven into cradle posts shielded infants from changelings. Norse sagas recount iron rings worn by warriors to repel draugr and dark álfar. African diaspora hoodoo buries iron horseshoes beneath doorsteps to trap jinxes and evil walkers.

Hang an iron cross above your door to bar entry to the Good Folk, place a horseshoe open-end up to catch ill-luck. Each piece is raw, cold iron—pure and unforgiving.
