- Historical-Domain Character: Lots, naturally. Notably Machiavelli, who appears in the short story in the last chapter telling war stories with a pair of mercenary officers. Only his first name is given, but it is pretty easy to infer.
- Last Stand: In the first chapter, the story is told of a Roman Cohort in Britain, Trapped Behind Enemy Lines and wiped out.
- Short Story: A short story is given at the beginning of the first and last chapters.
