Following that day, the undead really tried to hammer in their aspects of death into the heads of the people of this realm, from what they understood, the aspects were expressions of Death itself, and plenty of the clerics tended to specialise in a single aspect, bringing it up to its maximum application, similar to how some monks might starve to death by lengthy fasting, they were so dedicated to that one aspect, that it practically moulded them into entirely new individuals.
Some of the preachers were part of those that wholeheartedly focused on a single aspect, but only two or three so far, most were more regular, deacons, priests, monks and the likes, simple members of the church without clear specialisations, and it quickly became apparent that the church was a wide-reaching group as the undeads part of it were of many different species, some were naturally spawned, some had been alive once, but all had that same flame of faith burning within them.
