you have me pretty excited and curious.
I know you want your audience to imagine the main character and that makes sense to a degree but some basics will likely (perhaps?) be necessary down the line, knowing what the main character is proficient in might help determine what/how they'd do and say things.
I know I have knowledge that the main character clearly does not but the specific knowledge they have is unknown to me at this point,
I am unable to cut out the unnecessary knowledge without knowing a scope.
I am very curious how you will handle this but don't tell me, I'll just consider this another good reason to watch for updates.
