Parasite of Prayer

From publisher blurb:

The Black Sea of Void surrounding Erenel is home to Eldritch gods known as the Null. One of these otherworldly beings is the Parasite of Prayer. A Null who steals worship, feasting on temples and clergies, spreading secretly amongst the clerics and priests unaware of the shroud that has befallen them. You've made a pact with the Parasite of Prayer, helping the Eldritch god to consume and spread spiritual nullity. For those who use divine power, prayer feels like a conversation with someone who is silently listening. In your presence, prayer feels more like talking to an empty room. A meaningless distraction.
