Drak'hul was a Drakh who in the 15th Century visited Earth for a time to study humans. Taking up residence in the region of Wallachia he kept mostly out of sight, seen by only a few. Word however spread among the locals of a dark one who kept to the shadows, draining the souls of his victims and ruled them thereafter. The tales of his activities pervaded in human culture for centuries afterwards before becoming merged with those of Vlad Tepes, a cruel and brutal Prince of Wallachia who came to power during the same period.
