At some point in time Zephon and his clan assaulted the Silenced Cathedral, successfully taking it over from the human´s hands. Nestled safely in its furthermost chamber, Zephon had attached himself to the walls of the room after transforming, covering the walls with his flesh and essentially becoming one with the room. Since rendered immobile, it seems that he had to be fed human sacrifices which his soldiers would put into pods on the side walls. Much like a spider, he probably siphoned their blood to sustain himself over time.
