Interacting with NPCs can bulk out posts easily. For mine, I rehashed the history into what it means for my character in the "talk to the audience" format. The next part was after the awakening and showing what her life is like, with some casual banter to give a sense of the status quo before it all changed for the future. Then for the third part, I wrote something as potential plugs as to how she can end up at the academy, and I did a little exchange based on the FBI website for some narrative. Don't have to be intimidated by the size.
