From the description: On the top of a barren hill lies an empty castle. This place is doomed. Acid rains poor on the region days and nights, killing all life but a few horribly deformed reptiles. The song only remembers a name : Merecastle. And those fool enough to listen to the tune might find the riches left by the long dead inhabitants of the castle. Or death. The Rains of MereCastle is a Mörk Borg compatible Story Hook Song.
