Prehistoric times beyond the mist of vedic India - the forgotten era of 'first wave' civilisations. Around 10500 B.C.E., with sea levels much lower than they are today, and mainland continents still largely covered with ice, the primary centres of Indian civilisation were dominated by two highly advanced nation states - Dev Lok and Daityan Empire. Spiritually-inclined Devas lived in harmony with nature, whereas Daityas believed in brute force technologies for rapid prosperity and material gratification. Steady inundation of the tropical islands created a crisis, particularly for Daityas. To fuel their hunger for material resources, the aggressive Daityas proceeded to invade other nations. Warrior monk Hara becomes the sole hope of Dev Lok to prevent defeat and abject subjugation. However, before he can help them, Hara must undertake the ultimate journey of spirituality to pass beyond the barrier of death itself and engage with the astral personae of Lord Rudra. This action-packed mythological science fiction takes the readers through the exotic cities of Amaravati, Atalantpuri, and traces the arduous journey to Mount Kailash. The story unfolds the philosophy of Karma within the backdrop of love, passion, greed, war, tragedy and spirituality that characterised these ancient times. Will Hara be able to check the Daityan aggression in time to correct the course of Karma? Will he be able to wield the viman 'Pinaka' against the central seat of Daityan power - the indestructible citadels of Tripura? Is he the one who will glorify the name of Lord Shiva as Tripurantaka - the mighty destroyer of Tripura?
