Of course the priests that sold absolution are probably in hell right beside those who bought it if such a place even exists.
I'm sure it's quite possible IC that some smart NPCs or perhaps even a Player Character with religious background could charge
indulgences from the less bright people promising them that if they pay enough they will go to a much better place than the death realm, and perhaps even get 72 virgins(male or female) there, with really much payment...
What I find strange is that it is possible through the quest system to register yourself as a follower of Laanx even if you has chosen as your character faith "Talad", "Black Flame" or if your character shares a "belief" similar to the one of Richard Dawkins. Of course the answer is a bit obvious(SOON(TM)), and any person that takes roleplaying seriously won't do it from nowhere obviously, unless there is a damn good IC reason for the character to convert to Laanx religion, but that should require more than just paying 1,000 I believe. Perhaps some kind of bizarre ritual...
