Iniquity of the Fathers is our introduction to the author's Dynasty of Orphans chronicle. This book draws heavily of concepts introduced in Unleashed & Unfettered especially the concept of Generation & Refinement. This product also uses something called the Languor... which is very similiar to the Withering that was introduced in the Gehenna book. We are introduced to the Exiled, which are vampires descended from the various original clan founds... such as the true brujah.
Overall this book, provides a lot of set up, background info, and setting details for role playing a vampire game in a post Languor (Withering) setting. The Tabletop Gaming club found lots of interesting concepts in the book, and strongly suggests that other storytellers pick up a copy.
