I only remember this one scene, it was talking about how the last dragon, a golden dragon fell in love with a human and they had a child, later on the child fell in love with a woman and asked the dragon to give him one of his bones, the dragon did and created a sword, later on the dragon sacrificed his life for the son so that he could become king or something, it’s not the main plot but it’s like a history lesson (someone please tell me they know i don’t wanna download reddit to ask )
