If MC gets blessings of Kali Maa, it's game over for the rest. She is Shakti personified. I was thinking you can introduce Asuras and Devas resuming the millennial battle through Avatar. Personally felt Asuras were cheated out of their Amrut by the other side. Kali Ma is also worshipped by Asuras so it would kinda make sense in grand scale of things. Also you may want to put a huge disclaimer about this being being fictional just in case some one gets offended ;)
