Prince of Transylvania, Michael the Brave.

I looked at this photo today and realized how much facts and legends are in twined into the fabric of Transylvania.
This is Prince Michael the Brave who united the three provinces that became Romania. In 1599 this was a significant achievement, since many didn't want the provinces united. He was killed or murdered in 1600, and the provinces weren't reunited for a long time afterwards (After the First World War)
According to legend Michael brought hope and power to the Romanians of Transylvania. since he reigned for less than a year this is hard to believe. Yet, still that comment holds true.
Still there are other legends about Transylvania that are based upon real people and events. Who do you know that lived in Transylvania but became larger than life afterwards?
