1900 BC. In what modern Indians mistakenly call the Indus Valley Civilisation. The inhabitants of that period called it the land of Meluha ? a near perfect empire created many centuries earlier by Lord Ram, one of the greatest monarchs that ever lived. This once proud empire and its Suryavanshi rulers face severe perils as its primary river, the revered Saraswati, is slowly drying to extinction. They also face devastating terrorist attacks from the east, the land of the Chandravanshis. To make matters worse, the Chandravanshis appear to have allied with the Nagas, an ostracised and sinister race of deformed humans with astonishing martial skills.
