This is a single volume, compiled reprinting of the first three Iron Kingdoms products: The Longest Night, Shadow of the Exile, and Legion of Lost Souls. The three adventures have been updated to Dungeons and Dragons 3rd Edition Revised (3.5,) and two additional bridge adventures, Fools Errand and The Umbral Spire, have been added to the book. Also, the adventures have been revised to bring them in line with later published Iron Kingdoms materials. This is a full campaign, designed to take starting characters, and bring them up to approximately level 7 or 8.

The Witchfire Trilogy was originally published in three seperate volumes in 2001. The first of the two bridging adventures, Fool's Errand, was released exclusively as a PDF file shortly thereafter (its presentation in this book is it's first print edition.) The second bridging adventure, The Umbral Spire, was created for this adventure, and has since been released as a PDF for those who already had the other books and did not wish to get the reprint.
