Horseshoes from the Execution of François Ravaillac

Origin
In 1609, Ravaillac claimed to have experienced a vision instructing him to convince King Henry IV to convert the Huguenots to Catholicism. Unable to meet the king, Ravaillac interpreted Henry's decision to invade the Spanish Netherlands as the start of a war against the Pope. Determined to stop him, he decided to kill the king. On 14 May 1610, Ravaillac lay in wait in the Rue de la Ferronnerie in Paris (now south of the Forum des Halles); when the king passed, his carriage was halted by a blockage in the street, and Ravaillac stabbed Henry to death. Ravaillac was immediately seized by police and taken to the Hôtel de Retz to avoid a mob lynching.

After being interrogated, he said he did not fear death, as he had done what he had set out to do. After being tortured one last time, where "he was scalded with burning sulphur, molten lead and boiling oil and resin, his flesh then being torn by pincers," he was tied to and pulled apart by four horses.

Each of these four horseshoes belonged to one of the four horses that carried out his execution.

Effects
Each horseshoe will automatically tie itself to the nearest living limb via a rope of energy. Upon dong so it will begin to pull the limb in a direction it seemingly randomly chooses. If more than one horseshoe is used on the same person, they will always go in different directions. Using all four will almost guarantee dismemberment, as they are very fast to pull once they have attached themselves to their target.

Storage
To prevent activation, each horseshoe is kept in individual neutralizer bags, and separate boxes lined with neutralizer cloth.
