It's possible that there are other supernatural beings apart from the watchful gods. They could be allies or enemies of the gods. These characters, along with the gods and humans, would form a complex web of relationships that drive the stories forward. For example, a magical creature that serves the watchful gods or a rival deity that challenges their authority.
One interesting story might be about the watchful gods themselves. Maybe it details their powers and how they interact with the mortal world. Another could be a story of a character's encounter with these gods and how it changes their life.
As we don't know the details of the 'watchful eye story', the main characters could range from a magical being with a watchful eye that guards a forest, to a young child who is the focus of someone's watchful eye, like a grandparent. There could also be a villain whose actions are being watched by a hero, so the main characters could be a hero - villain duo in this case.
I don't know as I haven't read it. It could be a single protagonist with the watchful eye as their main characteristic, or it could be a group of characters where one has the watchful eye and the others are related to them in some way.
Since I don't know the specific 'under the watchful eye fanfiction', it's hard to say. It could be characters from the original work it's based on.
Obviously, Percy would be one of the main characters. He is the one doing the learning. There might also be other demigods who join him in this journey of discovery, like Annabeth. And of course, the other gods themselves could be considered important characters as Percy interacts with them.
Often, the main characters are the new gods themselves. For example, a new god of art might be a central figure, creating masterpieces and inspiring humans to be more creative.
Well, without having read the specific 'gods little acre stories', it's difficult to say precisely. However, in a story about a small acre of land, we can assume there would be a landowner or tenant who is central to the plot. There may also be neighboring characters who interact with this main figure, perhaps an old wise neighbor who gives advice, or a young adventurous neighbor who brings new ideas into the community.
Since it's 'The Monster and Other Stories', there may be a group of adventurers as main characters. They might be on a quest that leads them to encounter the monster. Each of them could have different personalities and skills. For instance, one could be strong and fearless, while another is intelligent and good at solving puzzles. And of course, the monster itself could also be considered a main character in a way, as it drives the action and conflict in the stories.
I'm not sure as I haven't read the specific 'neighbors and other stories'. It could be the neighbors themselves, perhaps an old couple next door, a young family, or a single person living alone.
Given the title, it's likely that the main characters are the 'other women'. These could be women from different walks of life, each with their own story to tell. There may also be other supporting characters like friends or family members who influence or are affected by the situations these other women are in.
