The Fourth Lannister. [Jon Snow]
Elena Lannister, the youngest child born to Tywin Lannister, the most powerful man in Westeros, and the late Joanna Lannister, who passed away during child birth.
Elena was born a Lannister, but did not share the personality that was common in one from her house. She was curious about the world, and held hope that her older siblings would soon regret their immoral actions.
Her family could be known as being the most powerful house in Westeros, with her older sister Cersei being the Queen, her brother Jaime in the Kings Guard, and her other older brother Tyrion, being a Dwarf.
This is the story of the fourth Lannister, who always had her future set out for her, who's life changed the second she met the bastard son of one of the greatest Northern Houses.
