Perhaps they are from rival kingdoms that have been at war for generations. They meet by chance in a neutral territory and instead of fighting, they start to talk. They realize that the war has been caused by misunderstandings between their families. So, they decide to work together to end the war. They face opposition from their own families and kingdoms, but their love for each other gives them the strength to persevere and bring peace.
One possible storyline could be a powerful new enemy emerging. This enemy could be a long - lost primordial being. They manage to overpower Percy and Annabeth in a battle that was unexpected. Maybe they were lured into a trap where their powers were nullified, and they couldn't fight back effectively. Another storyline could be a self - sacrifice. For example, to save their friends or the whole of Camp Half - Blood, they choose to face a great danger alone, knowing that they won't survive.
Princess Annabeth is often depicted as highly intelligent. She uses her wits to solve problems and strategize. For instance, when dealing with threats to the kingdom, she can quickly analyze the situation. Prince Percy is usually brave. He doesn't shy away from danger and is always ready to fight for what's right. In many fanfictions, he might be the first to charge into battle to protect the princess or the kingdom.
One possible storyline could be Percy and Annabeth dealing with the emotional aftermath. They might struggle with feelings of guilt and grief. Percy could become overly protective of Annabeth, while she might feel like she has failed in some way. Another storyline could involve them seeking support from their friends in the demigod community, like Grover or Piper, who help them through this difficult time.
One common theme is love against all odds. Their different kingdoms or social statuses might create barriers, but they always find a way to be together.
One possible storyline could be that in a battle against a new and powerful enemy, Annabeth sacrifices herself to save Percy. Maybe she steps in front of a deadly attack meant for him, like a powerful magic blast from a primordial being. This would shatter Percy, leading him on a journey of both revenge and self - discovery as he tries to come to terms with her loss.
Prince Percy was known for his bravery and Princess Annabeth for her wisdom. In the fanfiction, a great evil threatened their kingdoms. Percy wanted to fight it head - on with his sword, but Annabeth advised caution. They argued at first, but then realized they needed each other. Percy listened to Annabeth's plan which involved gathering allies from all over the land. Together, they led the fight against the evil, and in the process, their bond grew even stronger.
One possible storyline could be their children going on a quest to discover a new hidden part of the demigod world. Maybe they have to find a lost artifact that is crucial for the safety of Camp Half - Blood. Another could be their children facing challenges at school, dealing with both normal school problems and the added pressure of being demigods.
Perhaps they go on a quest to find a way to close the gates of Tartarus permanently. This would involve traveling to different places, facing new monsters, and using their combined knowledge and skills. Along the way, their bond would be tested, and they'd have to rely on each other more than ever, making their relationship even deeper.
One possible storyline could be that their daughter inherits both of their special abilities. For example, she might have Percy's skill with water and Annabeth's strategic mind. She could go on adventures in the same world as her parents, facing new monsters and challenges. Maybe she discovers a long - lost secret related to the gods that her parents were unaware of.
One popular storyline is Percy and Annabeth raising their demigod children and teaching them how to handle their powers. For example, their kids might struggle with controlling water or wisdom - related abilities. Another could be them building a family life while still being involved in the demigod world, like dealing with new threats to Camp Half - Blood while also making sure their family is safe. There are also fanfictions where they adopt other demigods who have no families and create a big, loving family unit.
