Book 1. The Bloody Baphomet. Diary of a Templar Crusader

Medieval France. Count Raymond IV of Toulouse, ruler of the kingdom of Languedoc, brings from the Crusade a certain statuette depicting Baphomet. He annexes more and more new lands to the kingdom of Languedoc. The wealthy Kingdom of Languedoc causes the envy of France, weakened by constant military conflicts with England.
Five years after returning from a campaign, Count Raymond is overtaken by a mysterious death in the highland castle of Montsegur. His son Alphonse leaves his native Languedoc forever, going to the Holy Land, where he meets Hugues de Paynes, the first Grand Master of the Knights Templar. After that, the Templars begin to worship Baphomet.
A century later, the statuette falls into the hands of Chevalier Clermont de Montsegur, great-grandson of the Count of Toulouse. His life is full of unpredictable turns, and death becomes a mystery to posterity. France conquers the Languedoc. The King of France pursues the Knights Templar and tries to destroy them in order to take possession of the treasures of the Templars.
The next owner of Baphomet, Auguste de Cavallon (Templar and personal secretary of the Grand Master de Molay) transports the gold of the Knights Templar to Scotland. He experiences turbulent adventures, and then becomes the preceptor (manager of the castle and surrounding lands, keeper of ancient knowledge, mentor for the younger brothers of the Order; he can also execute judgment) of Inverness Castle, in which the spiritual and magical knowledge of Europe and the Near East is concentrated.
Warning: The book may contain descriptions of violent scenes. The behavior of the heroes of the book (both men and women) does not correspond to modern canons. For life and morality in the Middle Ages were very different from today. I want to note that women were highly dependent on men and were forced to obey their will.
