Since we don't have the details of the story, it's difficult to say exactly. But it's likely that the 'children of fire' themselves are the main characters. There could also be some adults or other creatures in the story that interact with these children, like a wise old mentor who guides them, or an antagonist who tries to stop them from using their fire - related abilities.
Maybe it's a victim of the fire. Someone who has lost their home or loved ones in the fire could be a main character, and the story could revolve around their journey of coping with the loss and trying to rebuild their life.
One possible theme could be transformation. Since fire is often a symbol of change, the 'children of fire' may go through some sort of personal transformation. Another theme might be the struggle between the ordinary and the extraordinary. If these children are special in some way related to fire, they may face difficulties in fitting into a normal world.

In a 'fire watch short story', the main character is probably the fire watcher. This character may have a backstory that led them to this job. Maybe they have a family to protect, or they are doing it as part of a community service. There could also be other characters like a fellow fire watcher with whom they share their shift. This person could be a friend or someone with a different personality, which might lead to some interesting interactions. And there could be a character who represents the authority in the area, like a ranger if it's in a forest or a building manager if it's in a building, who gives instructions or sets the rules for the fire watch.
I haven't read this short story specifically. But generally, it might be about some special group of 'children of fire'. Maybe they have some unique experiences or powers related to fire.
