From the back of the book: With five shards of the Shattered Starsecure, visions point the PCs toward one of Varisia’s most remote corners as the site protecting the sixth fragment of the powerful artifact. Yet the heroes are not the first to search for this shard—upon arriving at the ancient ruin known as Guiltspur, they find a small army of giants excavating the site on the order of a blue dragon. Even this is not the entirety of the danger, however, for as the heroes soon learn, there are other forces searching for the final shards as well—some hailing from the Darklands below, and some from beyond reality in the nightmare realm of Leng!
