Obviously, the daughter of Hecate would be a main character. Percy Jackson himself would also be a key character. And maybe Annabeth could be involved too. She could be a bit skeptical of the daughter of Hecate at first because of her association with magic, which is often seen as unpredictable in the Percy Jackson world.
The plot could also be about the daughter of Hecate uncovering a dark magic plot that endangers Camp Half - Blood. She initially tries to handle it on her own but realizes she needs help. Percy Jackson gets involved and they start to investigate. Along the way, they discover that the source of the problem is an ancient curse related to Hecate herself. The daughter has to come to terms with her heritage and use her powers in ways she never thought possible to break the curse and save the camp.
The Titans could still be antagonists. They might see Percy as a threat in his new role as the champion of Hecate. Another could be some rogue demigods who are jealous of Percy's new power and want it for themselves. And there could be magical creatures that have been corrupted by dark magic and oppose Percy's efforts to bring balance with Hecate's magic.
The Titans could be great antagonists. They might see the daughter of Hecate as a threat to their plans of taking over. Her magic could be something they want to either control or destroy.
A powerful sorcerer who once was a disciple of Hecate but turned to the dark side could be the main antagonist. He might be jealous of Percy being chosen as the champion and wants to steal Percy's powers for himself.
The Titans could still be antagonists. Since Percy has a connection to Hecate, they might see him as a threat to their plans of overthrowing the gods. They could try to capture him to use his powers for their own evil purposes.
Some of the old monsters from Greek mythology that have a vendetta against Aphrodite's lineage could be the main antagonists. Maybe a spurned former lover of Aphrodite who was turned into a monster. This monster targets the daughter of Aphrodite and Percy because they are symbols of Aphrodite's power and influence. It constantly tries to harm them and thwart their plans.
It could be some of the pure - blood supremacists. They might see her as an abomination because of her connection to Hecate, who is not part of the traditional wizarding families. They would try to undermine her at every turn and make her life difficult at Hogwarts.
The main characters are Percy and Hecate. Percy is a well - known character from the Percy Jackson series, often brave and with a sense of adventure. Hecate is a goddess in Greek mythology associated with magic. In this fanfiction, they are likely to be the focus, with their interactions and relationship being central to the story.
One possible plot could be Percy discovering new powers bestowed upon him by Hecate. He might have to use these powers to navigate a mysterious underworld realm filled with strange creatures. Along the way, he could meet new allies who are also under Hecate's influence.
Well, one possible plot could be Percy discovering new powers. Since Hecate is the goddess of magic, Percy might learn magical abilities he never knew he had. Maybe he starts to see magic in everyday things in a way he didn't before. For example, he could make inanimate objects come to life or use spells to protect himself and his friends. Another aspect could be his relationship with Hecate. She might be a strict but loving mother figure, teaching him about the deeper mysteries of the demigod world and how magic fits into it all.
