At the start of every chapter, the reader will encounter a [bracketed] section. For example, Chapter one: Surprise demon attack starts off with the following:
[JAMES HATAHLI. Inner London, London, England. Wednesday 7th of September, 1881 Gregorian Calendar].
This [bracketed] section sets the viewpoint, start location and start date of the story. So the above can be broken down as follows:
1) JAMES HATAHLI: Name of the viewpoint character. I write in third person viewpoint, which is the viewpoint used in many modern Western novels. For example Harry Potter and Song of Ice and Fire (Game of Thrones).
2) Inner London, London, England.: The starting location. It lists the City (or local region). Then the country (or geographic region). Ending with the world (or dimension).
3) Wednesday 7th of June, 1881 Gregorian Calendar: The starting date. It lists the day, the date and the year (as well as the Dating system being used).
