In the 1500s, Vlad III led a series of raids in neighboring Transylvania. Vampirism spread through the entire region as Vlad and his followers gorged themselves on their enemies. The city of Cluj became the site of the first vampire clan officially recognized by the Clave, and Transylvania took over as the epicenter of the vampire epidemic. During this time, Simion recorded details of the original spread of the plague and the events that took place.
