Black Breath

The Black Breath, a sinister aura emanating from the invisible Nazgûl, manifests as a terrifying malady in The Return of the King, plunging victims into deepening nightmares, deadly chills, and grey shadows upon their faces. This dread affliction underscores the Ringwraiths' otherworldly menace during the siege of Minas Tirith and key confrontations. Healed only by the rare athelas leaves in the hands of those with the right word of command, it highlights Aragorn's kingship and the fragile line between life and the Shadow's grasp.
