In Indic phraseology, tantra is knowledge, a yantra is a device to explore this knowledge and a mantra is the code that unlocks both the tantra and its yantra. Chronos is a sci-fi trilogy that recreates this framework where the first novel Chronotantra defines the contours of a tech driven, futuristic society, the second, Chronoyantra, describes a device used to explore the genesis of this society, while the third, Chronomantra finally reveals the code, the key, that unlocks this puzzle. As the grand culmination of this extraordinary science fiction trilogy, Chronomantra unfurls like a long-awaited revelation, casting light on the labyrinthine paths laid by Chronotantra and Chronoyantra. This final installment does more than tie together the threads; it redefines the very fabric of its universe, where technology, mythology, and human ambition coalesce.
