Hell doesn't really have a "religion" from which it can reliably draw Essence. Sure, there are some cults whose worship does in fact directly feed Hell, but they're very rare. Most "Satanists" have in fact had no contact at all with the Morning Star or his servants. However, Andrealphus and Nybbas have been rumored to be collaborating on a religion based on pure self-gratification. Many in Hell view this project with a little uncertainty, since its success could be a major boost to the already potent Words of Lust and The Media.
