Strange Amulet

The  is an enchanted amulet given to court-wizards of the Jarl of Windhelm. Wuunferth the Unliving was in possession of the amulet until it ended up in Hjerim at the crime-scene of Friga Shatter-Shield 's murder. The Dragonborn takes the amulet to Calixto Corrium for appraisal. Calixto says the amulet is powerless and worthless -- symbolic jewelry with no magical function. Eager to purchase the amulet and put it on display in his curiosity shop, Calixto agrees to purchase it for 500. After accusing Wuunferth of being The Butcher, he reveals the eight-sided, jade amulet carved with a skull is, in fact, an amulet used for Necromancy: the Necromancer's Amulet of Legend, once belonging to Mannimarco, the King of Worms. Following Wuunferth's instructions to meet the true killer in the Stone Quarters, the amulet can be found on Calixto's corpse, after his death.
