Jeyne Poole is the daughter of the steward of Winterfell, Vayon Poole.
In my fan fiction, Jeyne is one of the best friends of the Daughters and nieces of Eddard, Brandon, Benjen and Lyanna Stark.
Unlike the novels, Jeyne doesn't become a Whore, thanks to Cersei and Littlefinger, in one of his brothels, after the Lannister men killed everyone in the Hand's Tower, and beat Jeyne bloody until submission when she asked where her father is,..., nor is she sold to Ramsey Snow "Bolton" to become his plaything.
She becomes the wife and the mother of the children of Godric Dayne Stark, the second son of Brandon Stark and Lady Ashara Dayne, and heir to Starfall, but also the new Sword of the Morning who wielded Dawn, the sword owned by Ser Arthur Dayne, after he took his maidenhood, and ask her father to marry them, when she discovered she was pregnant.
