Hello. You did not enter the text to which this question refers. This makes it impossible to create a specific and exact answer, but I hope to help in the best possible way.
In order to create credible and complex characters within a historical setting, the author must present real places, where the characters develop their story, in addition the author must point out events that happened in the real world, as a way of leaving his characters associated with the world in that we live and identifiable as a realistic and well-built action, with all the complexes that the human being presents.
