ARYA
The time had come for Arya to tell her family about Bran the Builder, her magic, and how she helped Aegon defeat the Night King. Aegon came to Winterfell on his Dragon, he had promised to be there when she told them. So the Family gathers in the main hall and Arya tells them. Everyone reacts differently. Eddard and Catelyn Stark are angry that she kept it from them. Sansa is intrigued especially about the part that her Ancestor had considered giving her his magic. Robb is thankful for Talisa and the tragedy they avoided. Bran and Rickon are curious and want her to show them her magic.
It takes a while for her parents to forgive Arya, but they eventually do. Jae's presence did ease tensions somewhat. Lord Stark calls the family together, "You all are getting older. One day you will marry and have children of your own…I have often said…When the cold winds blow, the pack survives, but the loan wolf dies…No more secrets in this family and teach that to your children and make sure they pass it on together…We are stronger together…"
"Family!' Robb says with his arm around Talisa. They all repeat what he said.
Arya smiles thinking about what could have happened, compared to what did happen. She looks forward to her future with Gendry. Eventually she and Gendry marry at Winterfell. They will have to wait until the long winter ends before Moat Cailin can be built and then they can move in. They also wait to have children and spend their days getting to know one another.
The Winter lasts just six years, the first Winter it snowed in the South and in Dorne. The King hosts a tourney to celebrate the victory over the dead, the summer and his son's name day. The largest tourney to be held since the one at Harrenhal. The Tourney is so big that it lasts two weeks, during which time several betrothals happen including Sansa's to Willis Tyrell and Bran to Myra Reed.
After the tourney Daenarys prepares to leave for Volantis and begin her conquest of the east. While Aegon cannot go he does send his Dragon with Dany. Tyrion's Dragon Joarrix is old enough to ride. He and Shae have four children together all of normal height. Twin girls Joanna and Tara and a son named Jaime. By the time Moat Cailin is finished Arya is pregnant with her first child.
Sorry for this ending if I find the inspiration I will will most like rewrite or add onto it but for now this is it
