need fun campaign map ideas

[lightning brigade]

I am making a map called tales of stories. It's a philosophical campaign based samuel iojin. An ex onubin slave who finds out from a master scribe named oriph he is a lorekeeper. I wanna the campaign fun and cool but I need ideas for the maps. I want it to be sorta linear. For example, one map starts off in a linear fashion then you're standing on a tower and down below enemies are assaulting. You gotta defend it by clicking on the enemies to kill them(chapter 3).

Make chapters like Polar Escape, or like Vampirism, where you have to escape some monster for a time. It's not original but it's new in single-player campaigns,
