Vampirium is the twenty-seventh book of the award-winning Lone Wolf series of gamebooks created by Joe Dever.
Lone Wolf books rely on a combination of thought and luck. Certain statistics such as combat skill and endurance attributes are determined randomly before play (reading). The player is then allowed to choose which Kai disciplines or skills he or she possess. This number depends directly on how many books in the series have been completed ("Kai rank"). In his first book, the player starts with five disciplines. With each additional book completed, the player chooses one additional Kai discipline.
