Devi is a fictional character created by Shekhar Kapur and Virgin Comics, as part of their debut Shakti line, which focuses on Indian settings.
After defeating Bala through hand-to-hand combat, which led to the fallen god being blinded, captured, and imprisoned by Bodha, the supreme Lord of creation inside Jwala, the fortress of fire and stone (hidden deep within the earth) she had created a source to hold the prayers of humanity and channel them to Akashik, the story's representation of heaven, thus replenishing the powers of the other pure gods.
In the present, a woman by the name of Tara Mehta, who is the unawakened Devi incarnate, lives a posh lifestyle alongside her boyfriend Iyam (who was the former favorite general of Bala during the ancient battle, and currently Sitapur's most notorious ganglord).
Meanwhile, Kratha, an Apsara - an assassin of heaven hired by Lord Bala using a woman named Amara Gaelle - goes to try to eliminate Tara Mehta before she becomes Devi.
Amara, Lord Bala's contact, kills 2 of Iyam's bodyguards who had captured Inspector Rahul thus freeing him and seemingly following her own agenda.
