What significant event occurred in Jimmy Kapoor's bedroom in the novel, Two Years Eight Months and Twenty-Eight Nights?

Jimmy lived in Queens, creating comics of a Shiva-Superman fusion in his free time, working for his cousin Nirmal/Normal as a tax accountant. He lived with his mother because he could not afford his own place, and he hated his job. The first wormhole to the jinn world after centuries opened in his bedroom, and he was the first Duniazat whom Dunia made aware of their power.
