"Some loose ends will be left deliberately open for the readers to interpret. As for losing someone we love? The Shiva trilogy chronicles a battle against evil. And evil does not go quietly into the night; instead, it puts up a strong fight against Good. So yes, people will die in Vayuputras," he concluded. Explaining that he wrote it as per his whim, and not according to the need to have more philosophy or love or war, Tripathi was sure that The Oath of the Vayuputras would have a tragic ending. During an interview with Daily News and Analysis, Tripathi explained that he had purposefully used the modern terms for the different historical locations described in the book, including calling India by its name, rather than its ancient name, Jambudweep. He did not believe that India could be represented as a political concept in his book, since at the timeline followed in the Shiva trilogy, India was still a cultural concept. Since some of the characters have their mythological names, but do not follow the characteristic traits, Tripathi believed that such development was spontaneous and did not question his writing further. Giving an example, the author said: "When I was writing the first book, I was struggling with the Naga, because I wanted to desperately change his character – that he should be jovial and happy. But he kept ending up as a tormented and troubled a guy who was suffering. And I just had to surrender" The cover art of the book was launched in Mumbai, by Tripathi and Johar in a ceremony, which also saw the presence of Gautam Padmanabhan, CEO of Westland Publishers, and Rashmi Pusalkar, the designer of the cover of The Oath of the Vayuputras. The author added that Pusalkar had managed to merge in many of the symbolic elements represented in the storyline of the book, while maintaining the same visual appeal of the previous releases of the trilogy. He wanted the cover to have a symbolic meaning, portraying Shiva wielding Pinaka—the legendary bow of the God according to Mythology—and a burning bush behind him. The increasing brightness of the book covers signified the triumph of good over evil, according to Tripathi. The UK publication rights of the Shiva trilogy, including The Oath of the Vayuputras was purchased by Jo Fletcher Books, with the deal being made by Claire Roberts at Trident Media Group,
