I think it is funny that when *you do a spoilery thing* in the game and the ground is blessed at times, you take damage as Fane from the surface. In my case he is the main character and also the one that triggered the events that are supposed to reward him. Turns out he will melt in the holy light instead.
A bit frustrating but I figure it was an easier solution than replacing it with a poison field if your avatar is undead, thus killing his friends; or adding a new type of healing that heals any friendly character regardless of race/tag.
