The probatio in question is Claudia, who shows up in the Fourth Cohort right after Gaea’s defeat, and right before all sorts of strange things start to happen. She quickly draws suspicion, in part because she’s a daughter of trickster god Mercury. This book is a personal journal that explores the events from her point of view.
