It has long been a well-known and non-negotiable teaching of the Church of Radiance that the dwellings of patchwork sorcerers or witches and the fields of great battles with them are cursed and forbidden. What is there to talk about when anyone who dared to break the taboo and go there would soon become seriously ill and die, not even by themselves, but with all their loved ones? Who would dispute this statement, knowing how many grave robbers and antiquities enthusiasts have fallen victim to the trinkets brought from such places?
But cursed sites keep cropping up.
These tend to be areas where the Lords and Ladies of Radiance have defeated the most dangerous spirits or malignant patchwork sorcerers. The Church hastily bans such places - they cannot be visited, much less lived in, and no one, on the threat of cruel punishments, dares take any item from them.
It would seem that, because of the lamentation of the Moon Child, such places should be sources of moon creatures, yet this is not the case. The curse doesn't work just on people - otherwise, why don't abandoned things come back to life?
The Church of Radiance supposedly knows rituals for cleansing cursed places, but they have only been used a handful of times in history regarding particularly significant places. In most cases, it is far too time-consuming and costly to attempt a cleansing, and it is more practical to construct a new building nearby and bury the cursed one, perhaps even literally.
