Schere's Disease

Schere's Disease is an engineered disease developed by the Tremere around 1900. It mimics vampirism, making its victims pale, allergic to sunlight, and slow to age. It is also hereditary, so that vampires who have themselves registered as Schere's Disease sufferers can disappear for a while and then post as their own children. The article that defines and describes it can be found in White Wolf Magazine #39, or in pdf form at pretty much any torrent downloading site.
