Well, a big theme is loyalty. The guardians are loyal to their duty of protecting the tent, and this loyalty can be tested in different ways in fanfiction. There's also the theme of discovery. Percy or other characters might discover new powers or secrets related to the tent or the guardians. For instance, they could find out that the guardians have a special ability that has been dormant for ages. And sometimes, there's a theme of friendship. Percy might form a friendship with the guardians while they are all working together to safeguard Thalia's tent.
There could be magical battles. Maybe some dark magic seeps into the tent, and the characters have to fight it off. For instance, a spell might be cast that turns the inside of the tent into a dangerous maze, and they have to find their way out while fighting off shadowy creatures.
In some fanfictions, Thalia's tent could hold secrets. It could be a place where ancient artifacts are stored that are relevant to the Percy Jackson world. Characters might stumble upon these secrets while seeking shelter in the tent. It could also be a place where new alliances are formed. Say, a character who was previously an enemy enters the tent and after some tense moments, decides to join forces with Percy and the gang.
There could be many fanfiction ideas around the Percy Jackson series involving a 'guardian' and a 'tent'. Maybe the tent is a magical place where the guardian protects Percy from some new threats. For example, it could be a tent that exists in a realm between the mortal world and the world of the gods, and the guardian has special powers to keep it hidden.
In a fanfiction of Thalia's memories as a guardian, it could explore her relationship with other characters like Percy. Maybe she has memories of when Percy first arrived at the camp and she was initially wary of him. But as time passed, she saw his potential and they became comrades. These memories could shape how she continues to protect the camp and those in it.
A really interesting fanfiction concept could be that the tent of Thalia has some sort of connection to the underworld. The guardians are constantly on edge, trying to keep the dark forces from using that connection. Percy Jackson stumbles upon this situation and decides to help the guardians. They end up having to go on a quest to find an artifact that can sever the connection, all while protecting Thalia's tent. This would make for a really exciting and action - packed fanfiction.
One great 'Percy Jackson Guardian Thalia Fanfiction' is 'Thalia's New Quest'. It shows Thalia in a whole new adventure, facing challenges that really test her skills as a guardian. The author does a great job of portraying her strong and independent nature.
It could be an old demigod who has retired from active quests but still has a lot of knowledge and power. Maybe someone like Clarisse's older relative who has seen a lot in the demigod world and is now tasked with looking after Percy.
One significant moment could be when she guards the entrance to a hidden demigod sanctuary. It's okay because it showcases her as a protector. By standing firm at the entrance, she's preventing any unwanted intruders from getting in and harming the demigods inside. This moment highlights her importance and her role as a guardian.
Thalia's memories as a guardian might include the time she patrolled the borders of Camp Half - Blood alone at night. The moon shining above her as she was on high alert for any signs of danger. This could be a really cool scene in a fanfiction.
Well, a frequent theme is the exploration of their pasts. In fanfiction, authors often delve into how Percy and Thalia's past experiences, both good and bad, shape their relationship. Also, the theme of sacrifice is quite common. They might be in a situation where one has to sacrifice something for the other. And of course, there's the theme of growth. As they fall in love, they grow as individuals and as demigods, learning to be better versions of themselves for the sake of their relationship.
