In 1938, renowned German archaeologist Dr. Werner Scheimberg leads a Nazi expedition to the enigmatic East. After deciphering an ancient map pointing to Agartha—the mythical underground city hidden for millennia—he knows he is on the verge of a discovery that could rewrite history. But he is not the only one after the secret: ruthless mercenaries and secret societies lurk in the shadows, willing to do anything to seize Agartha's knowledge and treasures. From the desolate frozen wastelands of Siberia to the deepest caverns of the Himalayas, the quest becomes a deadly game of survival, where each step reveals unimaginable dangers and ancient traps.

Decades later, in the present day, the Bluthund Community—an informal group of fearless researchers—tracks down another lost treasure in the unforgiving Gobi Desert. After the Bolshevik Revolution of 1917, a Russian nobleman, surrounded by the aura of a mystical warrior, managed to restore the monarchy in Mongolia before falling into communist hands. In a desperate attempt to preserve the Mongolian legacy, he sent the mythical treasure to an unknown destination. The Bluthund team faces brutal Mongol bandits, sandstorms, and relentless pursuit by a rival organization working from the shadows. But what they discover in the Gobi leads them much further, to a decisive quest in Tibet, revealing secrets both astonishing and disturbing.

Two expeditions, two eras, one mystery: the fates of those who dare to challenge the unknown are inextricably intertwined. An epic historical thriller that merges archaeology, mythology, and relentless adventure. For lovers of action-packed mysteries and ancient secrets, this story promises to keep you on the edge of your seat until the very end.
