the origin of Rider and Dragon

How Ratha and his rider met, Emiko is a huntress, and finds an egg in a burning rathian nest, she kills off the supposedly frenzied rathian, and takes the one surviving egg home, it hatches later on into a rathalos, the male version of a rathian. The rathalos acts gentle towards emiko due to its imprinting, and aggrsive towards everything else. This rathalos will be Ratha, and emiko will be the first hunter to become a rider.
