Bulgar (The Bellova Devil) as this is about an individual Bulgar, not the entire ethnic group.
Talk about it here.
A Bulgar led a group of Bulgars in London who were originally from the Bellova Forest. He believed Clive Colville was a vampire who had returned from the dead and encountered George Litefoot when laying a trap for Colville's return at his grave, but was frightened off by Henry Gordon Jago pretending to be a gang of police officers. When they finally encountered the who they thought was Clive Colville, they killed him. In actuality, it was his son, Reginald Colville that they had killed. Afterwards, two of the Bulgars fled for Constantinople. (AUDIO: The Bellova Devil)
