Infinite Horizon: Nocturne

Infinite Horizon: Nocturne is a stand-alone story in the Infinite Horizon series, unrelated to the storyline of Books 1-3. Instead of separating series by dimensional sectors as in Books 1-3, all series in Nocturne take place within the same world. The main setting of the story is Trinity City, a sprawling metropolis divided into 3 distinct districts overlooking a bay. In the center of the bay is the mysterious Bay Cathedral, which is rumored to have existed before the city was founded.

Trinity City
Trinity City is a massive city that is divided into three districts.

Traditional District
The Traditional District is what you would call the "normal" part of the city, where a majority of Trinity City's residents live. Gekkoukan High School and Nanoha Takamachi's elementary school are located here as well.

Versailles District
The Versailles District is sometimes referred to as the "rich people" district. Many of the buildings share a Victorian motif, and is home to L'École des Cinq Lumières and Ohtori Academy.

Industrial/Protestant District
Originally known as the Industrial District of Trinity City, due to being the location of most of the city's factories, this third of the city was bought out by the mysterious Royal Order of Protestant Knights, also known as the Hellsing Organization. Since then, everyone who had lived there were allowed to stay, but no one else has been allowed to move in.
