Prithvi, a twenty-one-year-old, is searching for a mysterious middle-aged aghori (Shiva devotee), Om Shastri, who was traced more than 200 years ago before he was captured and transported to a high-tech facility on an isolated Indian island. When the aghori was drugged and hypnotized for interrogation by a team of specialists, he claimed to have witnessed all four yugas (the epochs in Hinduism) and even participated in both Ramayana and Mahabharata.

To prepare for the future, our ancestors created the Naga sadhus―a clan of warriors for the protection of Dharma, as proclaimed by Adi Guru Shankaracharya in the eighth century. This sect of Shiva devotees has stood firm, living selflessly and fighting fearlessly. For centuries, they have died the death of heroes, serving and saving Dharma and the temples.

Phones stop working. Smartwatches die. And arms start glowing with blue scars. This is what happens to Aman Chandra and ten other Souls of Samsara when they are kidnapped from modern-day India and transported to a hidden valley in the Himalayas. In this realm of magic, home to Hindu gods, immortal yogis and mythical beasts, the mission is clear for the Souls of Samsara: to learn the ancient art of yogic sorcery and prepare for a treacherous journey not many can survive.

Aryavarta, the ancient realm of the noble. For generations the Firstborn dynasty of scholar-sages, descendants of Vasishta Varuni and protectors of the Divine Order on earth, has dominated here. For just as long, the Angirasa family of Firewrights, weapon-makers to the kings and master inventors, has defied them. In the aftermath of the centuries-long conflict between the two orders, the once-united empire of Aryavarta lies splintered, a shadow of its former glorious self.

India, 1025 AD. Repeated attacks by Mahmud of Ghazni and his barbaric Turkic hordes have weakened India’s northern regions. The invaders lay waste to vast swathes of the subcontinent—plundering, killing, raping, pillaging. Many of the old Indian kingdoms, tired and divided, fall to them. Those who do fight, battle with old codes of chivalry, and are unable to stop the savage Turkic army, which repeatedly breaks all rules to win. Then the Turks raid and destroy one of the holiest temples in the land: the magnificent Lord Shiva temple at Somnath.

The Aryavarta Empire stands on the brink of destruction.

He has been driven to madness by betrayal and failure, and he has become the greatest enemy that Aryavarta must face.

And does he want to be that hero at all? Drawn suddenly to his destiny, by duty as well as by love, will Shiva lead the Suryavanshi vengeance and destroy evil?
