I'm not entirely sure as I haven't read the book recently, but they could be scientists involved in the bomb's creation, military personnel dealing with the bomb's security or potential use, and civilians affected by the bomb's presence.
There could be the elder weremunk. This character would be very wise and have a lot of knowledge about the history and traditions of the weremunks.

In an 'Alvin and the Chipmunks Family Reunion Fanfic', Alvin, Simon, and Theodore are bound to be the central characters. They are the ones that most fans think of when they think of the Chipmunks. However, it could also include some of their extended family members. For example, an old - wise - looking chipmunk uncle who has stories from the past to tell. Or perhaps a young and mischievous chipmunk cousin who causes some light - hearted chaos during the reunion. And don't forget about Dave, who has been like a father to them.

There could also be a school principal who has to deal with all the chaos that the chipmunks sometimes create.
Fans of the genre that the Alvin story belongs to would probably be the main audience.

Also, those who are into character - driven stories that focus on emotions might also be interested.
