The story of the love of two life-and-death friends, a white Czech exile and a black descendant of Songhai emperors, for a single woman takes place in 16th century Africa, where powerful empires with advanced culture, a high level of education and strong ties to the then Christian world even the Muslim ones maintained equal diplomatic relations with developed states in all parts of the world, but due to mutual intolerance and imperfect armament, they hardly resisted the pressure of ruthless slavers. Empire after empire collapses at the heels of the heroes of the Black Saga, and the reader thus becomes a witness to the destruction of the Black Continent. It is Africa in the last minutes before the demise of its original civilization.
