Caballistics, Inc is a horror/fantasy story, set in the present day, that has been running in the weekly British anthology comic 2000 AD since December 2002.
The Department, by then consisting only of the crusty paranormal historian Dr Jonathan Brand and his assistant Jennifer Simmons, is bought by Ethan Kostabi, a reclusive multi-millionaire 1970s pop star.
Kostabi announces that he has contracted their services as part of a new private ghost-busting outfit, to be known as Caballistics, Inc., and introduces them to their teammates, freelance occult investigators Hannah Chapter and Lawrence Verse.
At least three members of the team were killed in the ensuing battle in addition to Kostabi himself, with only Ravne and Simmons known to have walked away unharmed.
