The rules state that every epic fantasy must be a trilogy and that the heroes and heroines must complete three adventures and hence VOTDG should be the third and last installment. In the last adventure, the Dark Baron was defeated once again and this time banished to Earth prime (e.g., our world). Several years have passed and now a new threat emerges, but this time from our world. The Baron was down, but evidently not out and, in league with another ostracized wizard and another demon from Hell are stirring up trouble once again!
In Chalker's timeline of history for this series, Heaven and Hell reached a sort of compromise about 2000 years ago, each side recognizing that if the war continued it would bring about the final Armageddon. This does not prevent some lessor demons from intrigue, however, and we have seen once such demon make a pact with the Baron. Now, another demon has a deal with the Baron, and if our world falls, so will Husaquahr, the land of the Fairies and Ruddygore. Since Ruddygore is prevented from going to Earth prime, Joe and Marge, along with some others, must made the journey and stop the Baron once again!
This was a fun installment with the majority of the adventures taking place in our world for a change, and Chalker brings his humor once again. Of course we have many body changes and so forth, and this needs some editing and polish, but a fitting end to the series (until Chalker returned to it five years later). 3.5 stars.
