The White Tiger's Seal

Mahua has always topped Ancient History. This is not going to help her if the ancient coronation ceremony (?) she has gatecrashed isn't part of a movie shooting. "Who are you?" the extremely displeased hot dude dressed in a towel (a toga?) asks, and somehow her brain processes the answer as the ancient - the ancient language of the Indus Valley - WAIT. Oh, my god, she's four thousand years back in the past. Everyone is still staring at her, waiting for an answer. Mahua sweats, and then makes an impulse decision. "I," she announces, "am a Sacrifice."
