This is a tier 2 (level 5-6) adventure about a strange fever that causes the population of the city of Andurias to suffer debilitating nightmares and night horrors. Some of those afflicted have started to become deranged and aggressive. It is only a matter of time before the city succumbs to chaos and destruction. A local librarian claims that there should be a way to track down the origin of the disease in the Grand Library's documents.
This adventure brings the characters to an ancient vault in the search of a disk key. With it, they will be able to access a bygone ruin under the city. The horror that hides therein is a dangerous immortal threat that scourged this land many times in the past. It is about to return. The nightmares are only a small manifestation of its true power. Only a group of strong, valiant warriors can expect to put a stop to this otherworldly threat from a bygone time.
