Calixto Corrium

Owner of "Calixto's House of Curiosities" in Windhelm, Calixto offers tours of the items he and his sister collected during their travels in Tamriel.

Biography
During his adult life, his parents died of unknown causes, bequeathing a large fortune to Calixto and his sister. Traveling Tamriel, they collected several rare items, such as the Book of Fate. Shortly after settling in Windhelm, his sister died, and he opened a curiosity shop in her name, to display their collection.

Blood on the Ice
Calixto is a museum owner, dubbed "The Butcher" by Viola Giordano. He kills women to perform necromantic rituals, in hopes of resurrecting his dead sister. One of his victims was the twin sister of Nilsine Shatter-Shield. Before coming to Windhelm, he was an adventurer, traveling and collecting artifacts and oddities. He criticizes the college mages for dabbling in magic with which they are already familiar, glamorizing the possible innovations of necromancy.

Crime scene and journal
He appears at the scene of Susanna the Wicked's murder. When questioned by the Dragonborn, he says he saw the culprit run off. When the Dragonborn discovers a Strange Amulet at Hjerim, he or she is directed towards Calixto. Calixto claims the amulet belongs to Wuunferth the Unliving and lies when he states that the court-wizard dabbled in necromancy before serving the Jarl. The Dragonborn can accuse Wuunferth of the crime, but he or she can also discover a hidden chest in Calixto's shop with the "real" edition of the Butcher Journal.

Learning the true culprit
Speaking to Wuunferth in the dungeons of the Palace of the Kings, the Dragonborn learns the murders in Windhelm have continued sInce the court-wizard's incarceration. Suspecting the killer will strike again that same night, he sends The Dragonborn to the Stone Quarter, where they find Calixto attempting to kill a random female. Preventing the murder, Calixto is killed and the murderous streak brought to an end.

Hired Thug
Stealing from Calixto may prompt hIm to hire thugs to teach the thief a lesson.
