In essence, A Darker Shade of Magic–or ADSoM for short–gave me a chance to turn my setting into not only a character, but an entire supporting cast. Through the four iterations of London, bound together by only a name, I was able to explore not only time, but also space, and the ways that different actions shape the world in which they happen. The color terms and relative absence/presence of magic are not the only things that set the Londons apart. Though each ones occupies the same geographical footprint, with the Thames (or the Isle, or the Siljt) at its heart, each city was inspired by a different part of the world, a different aesthetic, a different breed of empire. The worlds sit, layered like pages of paper in a book.
