Before Kara Ben Nemsi can return home from the Haddedihn, he is asked by Marah Durimeh to go to the Caucasus, where evil forces are invading the magical otherworld through an open dimensional rift, thereby endangering our world as well. Kara’s old friend Old Firehand has also settled in the solitude of the Georgian mountains; he has transformed from a hunter into an animal rights activist and has even learned to speak with animals. When he realizes that the unspoiled nature of the Caucasus is in danger, he becomes a relentless and merciless fighter.
