Kryp

Kryp, the vampire bat, wants to visit his master's castle in Transylvania, Romania
(GC5D8 Dracula's Castle by Team Romania).

Bran castle, also known as Dracula's castle, is situated on the border between Transylvania and Wallachia. In addition to its unique architecture, the castle is famous because of persistent myths that it had been the home of Vlad the Impaler; however, there is no physical evidence that Vlad ever lived there. According to most accounts, the Impaler spent two days in the Bran dungeon, as the area was occupied by Ottoman Empire at the time.

Vlad III the Impaler (Vlad Tepes) also known as Vlad Dracula or Vlad Draculea was voivode (prince) of the principality of Wallachia, now part of Romania. His three reigns were in 1448, 1456 to 1462, and 1476.
As voivode he led an independent policy in relation to the Ottoman Empire, and in Romania he is best remembered as a prince with a deep sense of justice and a defender of Wallachia against Ottoman expansionism. His impact on the expansion of the Ottoman Empire is recognizable in that his successful hold against them bought precious time for western Europe.

It is unclear why Bram Stoker chose this Wallachian prince as the model for his fictional vampire. Stoker was friends with a Hungarian professor from Budapest, and many have suggested that Vlad's name might have been mentioned by this friend. Regardless of how the name came to Stoker's attention, the cruel history of the Impaler would have readily loaned itself to Stoker's purposes. The events of Vlad's life were played out in a region of the world that was still basically medieval even in Stoker's time. The Balkans had only recently shaken off the Turkish yoke when Stoker started working on his novel and ancient superstitions were still prevalent. Transylvania had long been a part of the Austro-Hungarian Empire, but it too had endured a long period of Turkish domination and its culture was still largely medieval.
