In April of 1819, British officer John Smith was pursuing a tiger through the jungle outside of Mumbai when he stumbled upon a strange cave entrance hidden in the brush.
Something seemed oddly deliberate about the cave entrance and so he decided to abandon his hunt to investigate further. He soon discovered what appeared to be ornate carvings in the rock. Little did he know that was just the beginning.
