There would also be fans who appreciate the boldness of such a plot. It shows a different side of the story, a more tragic and bittersweet end that can add depth to the overall fanfiction universe. They might praise the author for taking risks and not following the typical happy - ending route.
One possible scenario could be they sacrifice themselves to save their friends. Maybe they are facing an all - powerful enemy that can only be defeated if they give up their own lives. For example, if there is a dark force threatening to destroy their entire world and the only way to stop it is by using their combined powers in a self - destructive way.
Percy's impulsive nature can be both a strength and a weakness. His quick decisions can sometimes get them out of immediate danger, like when he suddenly decides to charge at a group of monsters to create a distraction. Annabeth, on the other hand, is more calculating. She can rein in Percy's impulsiveness and make sure their plans are well - thought - out. For example, when they need to infiltrate a heavily guarded place, she'll come up with a detailed strategy and Percy will be the one to execute the more dangerous parts with his combat skills.
Another scenario might be during a dangerous quest. They get separated from the group and have to rely on each other for survival. In the process, they realize how much they mean to one another. They share their fears and hopes while huddled together in a cave waiting for the danger to pass. This intense situation could bring them together in a new way.
They might choose to run away because they want privacy. After all the battles and saving the world multiple times, they just want some time alone without any interruptions from other demigods or the gods. So running away seems like a good option.
There might be some fanfictions that depict Annabeth and Percy sharing a sleeping space in a very innocent and platonic way. However, it's important to note that in the original Percy Jackson series, their relationship is more focused on friendship, adventure, and a budding romantic relationship that doesn't involve such explicit scenarios. So, while you may find some fan - made stories that play with the idea of them sleeping together in a non - sexual way, it's not a common or central theme in most well - written and canon - respecting fanfictions.
Perhaps they run away because they are tired of all the rules and expectations placed on them. They just want to be free and explore the world on their own terms. They could end up in a small, idyllic town where they learn more about normal human life and each other away from the chaos of the demigod realm.
One great fanfiction is 'Early Bonds' where they start to realize their feelings much sooner. It has some really sweet moments between them during their early adventures.
They would probably have a lot of Greek - inspired decor. There might be statues of Greek gods and goddesses in the corners of the rooms. And some mosaics on the walls depicting scenes from Greek mythology, like the labors of Hercules.
They could have an adventure in an ancient, forgotten temple. Maybe they are on a quest to find a lost artifact that could save their world. Along the way, they use Percy's water powers and Annabeth's strategic mind to overcome various traps and monsters.
