The damned gold of the templars

Two Russian operas, who fell in the XIV century, fate throws one riddle after another. What is the fate of the children of the city of Hamelna and what kind of strange pipe was in the hands of Krysolov, who took them along? Where did the Gold of Templars go, looking throughout Europe by the Holy Inquisition? How to get rid of torture a Spaniard declared heretic and an evil witch? And finally, who is guilty of the death of the sister of the Tatar Khan Uzbek, who suddenly died in Tver?
And they have to find answers to all this, and at the same time think about how to save from the execution of the Tver Prince Mikhail Yaroslavich - the only one who is worthy to bring Russia to battle with the Horde hordes
