Well, it could be. There are so many different takes in the world of fanfiction. Some writers might be really interested in exploring the darker aspects of the Percy Jackson universe and see how it could interact with Erebus, a figure from Greek mythology. They might create stories where Percy has some sort of connection or encounter with the concept of Erebus, thus making it seem like a fanfiction about that connection.
One common theme is the exploration of the unknown. Erebus is a very mysterious place in Greek mythology, so fanfictions often focus on Percy's exploration of it. Another theme is the struggle against darkness, both literal and metaphorical. Since Erebus is associated with darkness, Percy often has to fight against the dark forces there.
One common theme could be the exploration of darkness. Since Erebus represents the primeval darkness in Greek mythology, in fanfiction with Percy Jackson, it might involve Percy delving into the darker sides of the mythological world he inhabits. For example, he could be facing challenges that are more related to the unknown and shadowy elements.
One common theme is identity. Since Percy is the son of Erebus, he has to figure out who he really is now. Another theme is acceptance. He has to deal with how others in the Percy Jackson world accept or reject him because of his new heritage. And of course, there's the theme of power. With his new connection to Erebus, he often has new and sometimes dangerous powers that he has to learn to control.
One common theme is the exploration of the power dynamics. Since Erebus and Thanatos are such powerful entities in Greek mythology, the fanfictions often deal with how Percy, as a demigod, can either challenge or be overawed by their power. Another theme is the idea of mortality and immortality. Thanatos being the personification of death and Erebus related to the primordial darkness, it makes for interesting discussions about life, death, and the afterlife in the context of Percy's world.
Yes, there are some really interesting ones. You can find them on various fanfiction websites. Just search using the keywords 'Percy Jackson', 'Erebus', and 'Thanatos' and you'll come across different stories with unique takes on the characters and their relationships.
There's often fanfiction that focuses on Percy's journey into Erebus. For example, he might be on a quest to retrieve an important artifact that has been lost in the depths of Erebus. This could lead to all sorts of encounters with strange creatures and powerful forces. Some fanfictions also explore how Percy's friends react to his forays into such a dangerous and unknown place.
The Furies could also be major antagonists. They are already powerful and feared in the Underworld, and Percy as the Champion of Erebus might be seen as a threat to their authority. They could try to undermine him at every turn, setting up traps and sending various minions after him. Additionally, there could be a new, unknown force emerging from the darkest parts of Erebus that is opposed to Percy's role. This could be a primordial being that has been awakened by Percy's ascension and wants to return the Underworld to a more chaotic and lawless state.
In this fanfiction, Percy is a character who is the son of Erebus. But without more context from the specific fanfic, it's hard to say exactly who he is beyond this basic family relation. He could be a new take on a well - known Percy from other mythologies or stories, with different powers and a different role to play because of his parentage.
One great 'Percy Jackson Son of Erebus' fanfiction is 'The Dark Prophecy of Percy'. It has an interesting take on Percy's new identity as the son of Erebus. The story is full of action and mystery, with Percy having to face new challenges that come with his dark heritage.
