In the fanfiction, their dream of the daughter could be about her role in the future of the demigod community. Maybe she is seen as a bridge between the different cabins at Camp Half - Blood, uniting them in a way that Percy and Annabeth had always hoped for. She could be shown as having a great understanding of the ancient prophecies and using that knowledge to bring peace and prosperity to the demigod world. As they dream, they feel a sense of pride and hope for what she could become.
Well, perhaps in this fanfiction's dream scenario, their daughter is on a quest. Percy and Annabeth watch in their dreams as she bravely overcomes various challenges, using a unique combination of Percy's water - related powers and Annabeth's strategic thinking. She might be accompanied by new and interesting characters, and along the way, she discovers a new part of the demigod world that was previously unknown.
One possible plot could be that in their dreams, they see their daughter growing up in a world where the threats they faced are no more. She is strong and confident, trained in the ways of the demigods. They dream of her making friends easily at Camp Half - Blood and having a special bond with the nature spirits there.
They might become more protective. Since they are dreaming of having a daughter, they would start to think about all the potential dangers she could face. Their relationship could grow deeper as they bond over their shared hopes and fears for their future child.
She could be a strong and intelligent girl, just like her parents. Maybe she has Percy's sea - green eyes and Annabeth's blonde hair. She might inherit Percy's ability to control water to some extent and Annabeth's strategic thinking.
Maybe there would be some initial tension between Percy and Annabeth's daughter. She could be rebellious and not want Percy interfering in her life at first. But as time goes on, they could form a strong bond. They might go on a quest together, where Percy has to save her from a dangerous foe, and that's when their relationship really starts to grow and develop into a more trusting and loving one.
Her adventures could start right in her own backyard, so to speak. She might discover a hidden entrance to an ancient labyrinth in her neighborhood. As she explores it, she has to use her wits and any powers she has. Later, she could be drawn into a larger adventure where she has to stop an evil force from awakening an ancient and powerful Titan. She would travel across the country, or even across different continents in the demigod world, encountering various mythical beings. Some might be friendly and offer her help, while others would try to stop her at all costs. And through all these adventures, she would grow in strength and wisdom, just like her parents did before her.
One possibility could be that they are in a school setting where they have to wear uniforms. Percy might constantly be getting in trouble for not following the uniform code properly, like having his tie askew or his shirt untucked. Annabeth, being more organized, tries to help him out. This could lead to some comical moments as well as deeper conversations about fitting in and following rules.
Well, perhaps Percy takes Annabeth on a quest to a special location, like an ancient Greek ruin they've always wanted to explore. During this adventure, he finds the perfect moment when they're alone and surrounded by the beauty of the place to pop the question.
It could be a beach day scenario. Maybe they are having a day off from their adventures and just relaxing on the beach in their bikinis and swim trunks, enjoying the sun and having some light - hearted conversations.
One possible plot could be their daily adventures in a new city. They might face challenges like dealing with strange neighbors or finding new jobs. Maybe they also have to hide their demigod powers from the normal humans around them.
The fanfiction could also focus on the relationship between Annabeth and Percy during this time. They might have disagreements on how to handle the situation. For instance, Percy might want to keep Annabeth safe at all costs and not let her go on any dangerous missions, while Annabeth feels that she needs to be involved to protect their child. This could lead to some tension between them, but in the end, they would work through it and become even closer as they anticipate the birth of their baby.
Perhaps in this fanfiction, a villain has somehow transferred Percy's power of hypnosis to himself and uses it on Annabeth to get information from her. Percy then has to race against time to break the hypnosis and save Annabeth, all while facing various challenges and obstacles set by the villain.
