Events

In 1462, a massive war between the Sultan's Army and Vlad III, or Dracula, took place in Wallachia; Vlad won. The Fifth Doctor, Peri Brown and Erimem materialised nearby, and ended up in the centre of the conflict. Vlad took Erimem with him to his palace, while the Doctor stayed with the Turkish rebels. Peri, meanwhile, was to be executed for trespassing on Dracula's land. She was saved from this fate at the last moment by the Doctor, and both were captured by Vlad. Erimem agreed to marry the prince in exchange for their lives. Their marriage was prevented on 2 July when circumstances forced the TARDIS team to depart. (AUDIO: Son of the Dragon)
