Perhaps Hecate appears to Harry in a vision during a difficult time, like when he's feeling lost after Sirius's death. She could offer him guidance on how to better understand the true nature of magic and his role in the wizarding world. This would give Harry a new perspective and a sense of purpose beyond just defeating Voldemort.
One idea could be that Hecate, being the goddess of magic, takes Harry Potter under her wing secretly to teach him ancient and powerful magic that Dumbledore doesn't know. This could lead to Harry having new abilities to fight Voldemort.
A possible plot could be that Harry's powers are not like the normal wizarding powers. Instead of using a wand in the traditional way, he might be able to draw on the power of Thanatos and Hecate in more instinctive ways. For example, he could use his connection to Thanatos to temporarily halt the aging process of an injured creature or use Hecate's power to create powerful illusions that are not just visual but can also affect the mind. This would make him a target for dark wizards who want to use his powers for their own evil ends, and he has to fight to keep his powers safe while also learning to control them.
One idea could be Percy seeking help from Hecate to break a powerful curse that has been placed on Camp Half - Blood. Another could be Hecate tasking Percy with a quest to retrieve a magical artifact that she needs to maintain the balance of magic in the world. Maybe Percy has to enter the realm of Hecate and face various magical trials to gain a new power.
Well, perhaps in the fanfiction, Percy is on a quest that involves an ancient magic artifact that is closely tied to Hecate. As he tries to find it, he has to enlist Hecate's help. Along the way, they face many enemies together and start to see each other in a new light. They might share some tender moments during their battles and while exploring the secrets related to the artifact.
Perhaps a plot point could be the new magical abilities Harry gains from being the son of Hecate. He might be able to control certain elements of magic in a way that other wizards can't. This could lead to him getting into both trouble and amazing adventures. He could also face opposition from some in the wizarding world who are suspicious of his newfound powers and origin.
One interesting story could be about Maris Hecate's role in the wizarding world during the time of Harry Potter. Maybe she has a secret connection to a hidden magical artifact that Harry and his friends need to find. Another could be a story where Maris Hecate is a teacher at Hogwarts and she imparts some unique and ancient magic to the students.
The plot could involve Harry growing up in a world where the boundaries between Greek and wizarding magic are blurred. Hecate could introduce him to magical creatures from Greek mythology. He might also have to face different kinds of dark forces that are more related to the ancient evils that Hecate has been fighting for centuries. This would make Harry a very different kind of wizard, one with a more diverse magical knowledge and power base.
In the fanfiction, it could start with Harry feeling a strange pull towards an ancient magic site. There he meets Hecate. Hecate is intrigued by Harry's unique magic, which has survived so many dark encounters. They begin to collaborate on magical research, and during this process, their relationship deepens into love. Their marriage unites the Hogwarts magic that Harry grew up with and the primordial magic of Hecate. This causes a stir in the wizarding world as many are both excited and fearful of the new power dynamics that will surely follow.
Well, it could be about Harry discovering his new heritage as the son of Hecate. Maybe he'd learn new magic that's related to Hecate's domain, like more powerful divination or magic over the crossroads. He could also face challenges from those who oppose a half - god in the wizarding world.
Well, in such a fanfiction, the plot might involve Hecate seeing Harry's potential not just as a wizard but as someone with a special destiny related to the magical world at large. She adopts him and begins to train him in her own brand of magic. This could lead to conflicts with the Ministry of Magic as they might see Harry's new powers as a threat. Also, Harry could use his newfound knowledge to better understand the Horcruxes and find a way to defeat Voldemort more quickly.
One idea could be that the daughter of Hecate uses her magic to help Percy in a quest that involves navigating through a magical maze. She could create illusions to deceive the monsters inside.
