The antagonists can also be popular in King's Maker fanfic. They create conflict and obstacles for the main characters, and their motives and backstories can be explored in more depth in fan - created stories. For example, a power - hungry noble who will stop at nothing to gain more influence.
One interesting plot could be the power struggles between different factions within the story's setting. This can lead to intense political intrigue and unexpected alliances.
Obviously, the toy maker and his daughter would be the main characters. There could also be the toys themselves, like a wise old teddy bear or a mischievous wind - up doll. Maybe there are other toy makers in the area who could be friends or rivals of the father.
I don't know the exact main characters as I'm not familiar with this specific novel. But they could be the weapon maker themselves, perhaps a young apprentice learning the trade, or an experienced master.
There's no way to be certain without reading the graphic novel, but perhaps the main character is an apprentice star maker. There could also be a mentor figure who teaches the protagonist the ropes of star - making. And there might be antagonists, like those who want to use the power of star - making for evil purposes.
It could be a young, talented wizard who has a natural gift for ring - making. Maybe Harry Potter himself might be involved, either as a customer or an inspiration for the ring - maker.
Since I don't have detailed information about the 'Star Maker AI Graphic Novel', I can't say for sure who the main characters are. They could be scientists or engineers who are involved in the development or control of the AI for star - making. Or perhaps the main character is the AI itself, with other characters being either its allies or antagonists in the story.
