In a fanfic, Percy and Artemis might have an adventure in a parallel dimension. This dimension is on the verge of collapse due to an imbalance between water and lunar energy. Percy and Artemis are called there because of their connection to these elements. They have to work together to restore the balance. Percy has to find the source of the water disruption and Artemis the lunar one. It's a long and difficult journey filled with many challenges and self - discoveries for both of them.
One adventure could be them exploring an ancient, forgotten island. This island has secrets that are related to both the sea and the moon. Percy's water powers would help them navigate the treacherous waters around the island, while Artemis' knowledge of the moon's magic could unlock the secrets on the island. They might encounter strange creatures that are a mix of sea and forest dwellers.
One possible adventure could be in the Underworld. Percy had some experience there already, and Artemis, with her fearless nature, accompanied him. They went to rescue a lost soul that was important to both of them. Along the way, they had to face the challenges of the Underworld, like getting past Cerberus and dealing with the tricky spirits that tried to deceive them. Their friendship was tested as they made their way through the dark and dangerous realm.
In this fanfiction, perhaps Percy would have to overcome many challenges. Artemis is a maiden goddess, so she might initially be very hesitant. Percy could start by showing his deep understanding of her values, like her love for nature and the hunt. He might bring her unique gifts related to these aspects. And he would need to convince her that their relationship could work, despite the differences between a demigod and a goddess.
One possible scenario could be Percy teaching Apollo and Artemis about modern mortal world. Percy could introduce them to things like skateboarding. Apollo would be excited and eager to try, while Artemis might be more reserved but still curious. They could bond over these new experiences and their shared sense of adventure.
One way it could work in a friends fanfic is if there's a parallel universe or alternate reality where the rules of the gods are different. In this realm, Percy and Artemis might be brought together under special circumstances. Their kids could then be a symbol of a new era or a new hope for the world they inhabit, and their friends could play important roles in protecting or raising these children.
The plot could start with Percy being sent on a mission that somehow intersects with Artemis's territory. Maybe he's looking for a powerful magical item that Artemis also has an interest in. At first, they might be at odds, with Artemis seeing Percy as an intruder. But as they face challenges together, like fending off a horde of mythical beasts, they start to respect each other. Percy's ability to think on his feet and Artemis's strategic mind work well together. Eventually, they realize they have more in common than they thought and form a friendship based on mutual respect and shared goals.
If Artemis wants a baby with Percy in fanfiction, it could change the power dynamics in the story's world. Artemis might become more protective and less involved in her usual activities as a goddess. Percy, on the other hand, might gain some new powers or abilities related to Artemis's domain. For example, he could have a stronger connection to nature or the ability to control wild animals. This could also create a new set of enemies for them, as some might see their union as a threat to the existing order.
There could be a love story. Artemis, now mortal, might develop feelings for Percy that she couldn't as a goddess. This would be a complex relationship as Percy already has his own life and relationships. The fanfiction could explore how they navigate these new emotions.
One possibility is that Percy's relationship with the other demigods would change. Since he is now under the wing of Apollo and Artemis, some demigods might be jealous or curious. He could also become a sort of mediator between the two gods' followers. For example, if there were disputes between the Apollo - related campers and Artemis - related hunters, Percy could use his position to resolve them.
They might inherit Percy's courage and Artemis' connection to nature and the hunt. Maybe they'd have the ability to control water like Percy and also be excellent archers like Artemis. Their personalities could be a blend of Percy's fun - loving and loyal nature and Artemis' independence and fierceness.
One possibility is that the collar is a key to a hidden realm. Percy discovers this when he picks it up. He then has to journey to this realm, which is full of strange and dangerous creatures that are somehow related to Artemis. Along the way, he makes new friends and enemies as he tries to figure out how to use the collar to get back home.
