Shadowrun has a disease called Human-Metahuman Vampiric Virus. Depending on the strain of the disease, it turns humans (and some non-human) animals into different types of creatures of legend. HMHVV-I turns humans into vampires but turns elves into banshees. HMHVV-II tends to result in more feral creatures, while HMHVV-III (Kreiger-strain) turns any kind of metahuman into a ghoul.
Do any published Shadowrun adventures for any edition feature non-Ghoul Infected as an antagonist, objective, or Mr. Johnson? If so, which ones?
