Item from Kingdom of the Wicked by Kerri Maniscalco
An artifact of cosmic power disguised as two ordinary amulets — one silver, one gold — worn by twin witches who had no idea they carried the key to Hell around their necks.
The Horn of Hades is the trilogy's central MacGuffin and its most elegant deception. For generations, the di Carlo family passed down two horn-shaped amulets as protective charms, never knowing they carried an artifact capable of sealing or opening the Gates of Hell — and summoning the Devil himself. La Prima Strega split the Horn into two pieces specifically so that no single person could wield its full power, then hid the halves as children's jewelry. The revelation that the cornicello are actually Wrath's cursed wings transforms every scene in which they appear — every time Emilia clutched her silver horn for comfort, she was holding a piece of the man she would fall in love with. The Horn can lock the gates of Hell permanently or blow them open, and in the wrong hands, it could reshape the balance of power between the mortal world and the Seven Circles entirely.
In its split form: two small horn-shaped amulets called cornicello — Emilia's is silver, Vittoria's is gold. Each is no larger than a thumb, designed to look like the traditional Italian horn charms worn for protection against evil. Together, they form a single artifact of far greater size and power. In its true form, the Horn of Hades is not a horn at all — it is Wrath's wings, cursed by the First Witch into a mockery of mortal lore and hidden in plain sight.
