Since I haven't read the novel, I can't say for sure who the main characters are. But I assume the saint herself is a main character as the title centers around her.
Based on the title, the saint full of wounds is surely one of the main characters. There may also be characters who are related to the events that led to her being wounded and thus the need for vengeance. It could be her oppressors or those who she believes have wronged her. Maybe there are also characters who support her in her quest for vengeance or try to stop her, like other religious figures or common people in the story's setting.
I'm not sure about the exact plot as I haven't read it in detail. But generally, it might involve a saint who has endured many wounds seeking vengeance. Maybe she was wronged in some way and is now on a path to get back at those who caused her harm.
Since I haven't read it, I can't say for sure. But it might have a vengeful hero or heroine as one of the main characters, and perhaps the object of their love or someone who gets in the way of their vengeance as other main characters.
Since it's fan fiction, it could be the characters from the original work it's based on. For example, if it's based on a superhero story, it could be the hero who was killed and now is seeking revenge from the grave.

I'm not sure specifically as I haven't read the novel, but typically in a war - centered story like this, there would be a protagonist who is seeking vengeance. There might also be a villain or antagonist who is the target of that vengeance or who stands in the way of the protagonist achieving it.
There are likely to be Space Marines as main characters. They are often the heroes in the Warhammer stories, fighting against the forces of chaos.
I'm not sure specifically as I haven't read the novel. But it could have a vengeful protagonist, perhaps someone who has a personal vendetta against the royals. There might also be key royal characters who are the targets of this vengeance.
