Typically, the main characters would be the night witches themselves. They are the ones with their unique skills and personalities. There could also be a tribute from a more well - known district who befriends the night witches and becomes a sort of co - protagonist. And of course, there might be the villainous Gamemakers who are constantly trying to stop the night witches from causing chaos in the Hunger Games.
In this fanfiction, the main characters are surely the night witches. They are a group of female warriors with amazing flying skills. Each of them has her own backstory and motivation for participating in the Hunger Games. There could also be a mentor figure, perhaps an older night witch who has retired from active duty but still gives advice to the younger ones. And there might be a love interest for one of the night witches, like a male tribute from another district who she forms a connection with during the Games.
