The dragon Smaug had a mate and after his death and having no wings to search for another mate, she withered away inside a huge cave beneath the Lonely Mountain, but not before laying an egg that took a hundred years to hatch out, mainly because the egg contained a male dragon who came to be named Gaug because of his roar, and he found he had a craving for raw fish. After making friends with the Eagles he eventually meets the people of the lake whose homes were destroyed by his father Smaug.
