Translated from the back of the book:
"'Circles of Perdition'
The demonic realms to the east of Aventuria always present challenges for true heroes. In the north of Tobrien the forces of the Twelve Gods prepare a grand military strike, but before it can succeed, the right conditions must be assured which require to penetrate the darkest places of the Black Lands.
Circles of Perdition presents four adventures taking place in different trouble spots and converging in Tobrien, so they can be played individually or as a campaign. In the City Of 1000 Eyes the heroes must wander under demonic gazes to free a defector from Yol-Ghurmak. The Last Banner still needs to be found in Warunk, but when it flies on the right side, another victory for the forces of good is claimed. It is a true suicide commando to push forward to the dwarves of Beilunk and recover an important artefact, and Operation Pearl Biter also requires brave champions to ensure a grand victory."
