Drachenfels by Kim Newman - also known by his pseudonym Jack Yeovil - is a Warhammer Fantasy novel written in 1989 and is now published under, and considered part of, the Warhammer Horror genre.
The story follows a group of adventurers, led by Crown Prince Oswald and the intriguing vampire, Genevieve, as they travel to the home of the sinister Drachenfels in a quest to defeat him. This novel has a wide range of fully developed characters with an intricate narrative and clear French-Germanic influences.
