Amar Chitra Katha Vol. 761 Prabhavati Hindi

The demon, Vajranabha, performs severe penance. Pleased, Brahma grants him the city of Vajra and says that not even air will enter the city, unless Vajranabha wants it to. Now, powerful in his impregnable city, Vajranabha turns his sights on Indra's kingdom. Indra goes to Krishna for help. What Vajranabha does not realize is that his daughter, Prabhavati, has set her heart on marrying Pradyumna, the son of Krishna.
