Gorka was a Master of the Night who wandered with his pack of un-deads between central and eastern Europe, taking advantage of civil wars to prey on citizens and soldiers. He and Shrek were partners in crimes, such as human trading. Tesla was one of the people sold him by Shrek, and later got vampirized and turned into a slave. Gorka and his pack decimated Kurjak's squad at the beginning of the series, and the latter joined forces with Harlan to fight him.
