One possible plot could be Percy's struggle for survival on the streets. He might have to find food and shelter daily, facing challenges from other street - dwellers or the elements. For example, he could be constantly looking for a warm place to sleep at night during the cold winter months.
Maybe there is a social worker named Mrs. Johnson who is trying to help the homeless in the area. She tries to reach out to Percy, but he is initially hesitant because he has trust issues. These characters can all interact with Percy and shape his story while he lives on the streets.
Well, one possible plot could be Percy having lost his memory. He's living on the streets, trying to figure out who he is. Maybe he has these strange dreams about a sword and a camp, but he can't quite make sense of them. As he survives on the streets, he starts to discover he has some strange abilities, like being able to control water from the puddles during rainstorms.
Percy copes by holding onto his hope. He knows that his life on the streets is just a temporary situation. He spends his days looking for clues about how to get back to his normal life. He also tries to stay positive by remembering the good times he had at Camp Half - Blood. He tells stories of his adventures to the other homeless people, which not only helps him but also gives them some entertainment and hope.
One possible storyline could be that Hermione has lost her memory and ends up on the streets. She has to rely on her wits and some latent magic skills to survive. Maybe she befriends some muggles who are also homeless and they form an unlikely community, all while she gradually regains her memories and tries to find her way back to the wizarding world.
One possible plot could be that Peter has lost his home due to some financial difficulties or perhaps after a villain attack destroys his place. He has to use his Spider - Man skills to survive on the streets. He might start by finding safe places to sleep at night, like on rooftops where he can also keep an eye out for trouble. Maybe he befriends some street kids and protects them from local thugs, all while trying to keep his identity a secret.
Ginny would be very empathetic. She'd probably try to understand Hermione's situation from a female perspective. Ginny might try to get some female friends or relatives to help out, like bringing food or warm clothes to Hermione. Luna would be her usual unique self. She might think that Hermione is on a special spiritual journey and would offer her some very strange but oddly comforting advice.
In this fanfiction, Percy living alone could mean a whole new set of adventures. Maybe he's chosen to isolate himself after all the chaos in the demigod world. He could be exploring his powers in solitude, away from the distractions of Camp Half - Blood. It also might lead to some self - discovery as he doesn't have to rely on his friends all the time.
A big theme is the discovery of self - reliance. Harry, who is used to having some support at Hogwarts, now has to rely on his own instincts and Sirius' guidance. Also, the theme of secrecy plays a part. They need to keep their presence on the streets a secret from certain people in the wizarding world who might try to use their situation against them. This adds an element of mystery and danger to the story.
One possible story could be that Percy learned to be extremely self - reliant. He might have made friends with stray animals on the streets, like a dog or a cat that became his constant companion.
