The Chronicles of an Age of Darkness broadly tell the story of the events leading to the end of a dark age. The Chronicles defy the conventions of the fantasy genre, by including elements of science fiction, graphic violence, grotesque and macabre elements, and political cynicism. They are sometimes described as 'gritty' because of their realism.
The Chronicles differ from most fantasy or science fiction series by not telling the adventures of a main protagonist, on a particular quest, in sequential order. Instead, each book is written from the viewpoint of a different character, whose personality and objectives differ markedly from the protagonists of other books in the series. The novels are set over the course of about thirty years.
