The story could involve Arya bringing about a new era in the North. She might focus on improving the lives of the common people. This could include building better defenses, promoting trade, and ensuring fair laws. As Queen, she would have to make tough decisions. For instance, when dealing with food shortages, she might have to decide whether to trade with former enemies or risk starvation.
In the fanfic, Arya as Queen of the North could also have to deal with her past. Maybe she has nightmares about the people she's killed. But she uses these experiences to become a more empathetic ruler. She could start a school of combat and espionage in the North, training the next generation to protect their land, while also teaching them the importance of mercy and justice.
One possible story could be Arya using her assassin skills to protect the North. She might face threats from the South or from within her own territory. For example, there could be lords who don't want to be ruled by a young woman. But Arya, being Arya, would use her wits and combat abilities to outmaneuver them.
One major challenge would be political. There would be many lords in the North who might not accept her rule easily. They could be traditionalists who think a woman shouldn't be in charge. Arya would have to prove herself through her actions and leadership skills.
In a fanfic, Arya could be in the brothel to rescue someone. It could be a young girl who was sold into prostitution against her will. Arya, with her skills and no - nonsense attitude, decides to take matters into her own hands. She has to outwit the brothel owner and any guards, and this adventure in the brothel could be a new chapter in her journey of self - discovery and growth as a character.
One possible plot could be Arya using the brothel as a cover. She might be spying on certain characters who frequent the place. Since she has skills in disguise and stealth, she could blend in among the workers or patrons to gather information for her own purposes, like revenge or to aid in the political chaos of Westeros.
The plot might involve Arya training the dragon in secret. Since she has her skills in stealth and combat, she could teach the dragon to be a silent and deadly force. They could explore uncharted regions of Westeros together, uncovering secrets and perhaps finding new allies or ancient powers.
Well, one possible plot could be that Robb stumbles upon Arya in the chaos of war. He might be leading his troops and suddenly recognize her among a group of refugees or captives. Then he would immediately take her under his protection, ensuring her safety and vowing to take her back home. This would be a moment of great relief and joy for both of them, especially considering all the hardships they've been through.
Well, in a fanfic where Robb finds Arya, they could immediately start making plans to take back Winterfell. Arya's skills could be a great asset to Robb's military campaigns. They might also share stories of their experiences during their time apart, which could strengthen their bond.
In a fanfic where Arya gets captured, she might be used as a bargaining chip. Her captors could try to exchange her for something valuable, like a strategic location or a large sum of gold. Maybe they want to use her to manipulate the Starks.
In a fanfic, Arya could have a more elaborate plan. She might gather evidence of Walder's treachery against House Stark first. Then, she uses her network of allies (either those she made during her travels or some remaining Stark loyalists) to isolate Walder. She could stage a public trial of sorts in the courtyard of his own castle, where she publicly accuses him and then executes him, sending a strong message to all those who wronged the Starks.
One idea could be a story where Arya meets Lemon in a tavern during her travels. Maybe Lemon has some interesting information about Arya's enemies, and they form an unlikely alliance to take on a common foe.
A simple plot could be that Arya and Lemon cross paths in a forest. They both have different goals but realize they can achieve more together. So they team up to hunt down a group of outlaws who have been terrorizing the local villages.
