The Nephilim Curse

Ashish Bajaj and Rathik Kapoor are completely normal, average citizens who happen to be best friends in Cochin, India. But when a Nephilim meets them in the middle of the night to murder them -- both of their entire lives change entirely.

"Ashish," Rathik started to say, reaching in his back pocket for a gun. "Get ready to run."
Rathik's friend said nothing, for his memory came rushing back to him like a film running through his mind. He remembered now, that a cold hand reached out from the darkness that would drag him to his death.
"Rathik, we need to run. Weapons won't kill it. I tried." Ashish whispered, tugging on his best friend's arm. "We need to go, now. Before it tries to get us both."
"Okay, I just -- ah!" He fell to the floor, being forcefully pulled away. His terrified eyes glanced all around him as he desperately tried to grab for the couch and chair legs, the bedpost as his friend did, but nothing helped.
"Rathik!" Ashish yelled, his flailing arms chasing his friend to free him from the monster's hands. "Rathik, take my hand!"
"Ashish, I can't! Please, help me!" Rathik called back. Tears were overwhelming his eyes as he was still trying to save himself.
And suddenly, like a lightswitch being flicked on, Ashish felt something turn on inside him. Something like a mix between anger and glee and puzzlement came to life. A powerful rush flowed through his body and he instinctively held out his hand to face the monster who had shown himself like before. A bright and clear reddish-orange orb twice as large as his hand formed in his palm and it shot itself towards the creature. Once the orb and monster made contact, it imploded and left ashes fluttering to the floorboards.
Ashish felt the power surge shrink and he collapsed to the floor, out cold.
