A Gehenna cult is a group of individuals (almost always vampires) that is devoted to influencing events leading up to or during Gehenna, often with the objective or stopping or aiding the Antediluvians. While these cults vary widely and are often in opposition of one another, in general each focuses on one or more similar activities including: * Searching for Noddist lore and prophecies. * Discovering the location and activities of the Antediluvians. * Observing and destroying Methuselah. * Spreading their message and recruiting others.
