Above is an article that discusses the use of setting to advance the plot.
Seven important details to consider are place, culture, era, geography (physical), things, time and weather.
Place - Salem, Massachusetts / The (secret) Salem Society of Sorcery
Culture - It's contemporary North America, but under a magical Sorcery Society governed by the High Order. There are different classes to magic (fire, water, earth & air), as well as different magic practices. The Salem Society follows the practice and ideology of sorcery, but others such as the Realm in Edinburgh, follows the practice of enchantment.
Era - 2010s decade (with references to 1690s, 1960s-1990s)
Geography - Urban small city near the Atlantic Ocean
Things - Members of the Society have Familiar Companions such as Cats, Dogs, Rabbits, etc.. however these are characters more than props. Magical objects include Apples, Pears, Strawberries and Blueberries, spelled with capitals to distinguish from non-magical equivalents. The four fruits each correspond to the classes of earth, air, fire and water magic. (I've written an article before about the four fruits, but I may write more on some of these topics in the future.) Other objects include amulets worn by many of the characters (a sapphire icicle, a ruby heart, a diamond star and an emerald shamrock) which correspond again to the four classes of magic.
Other general objects include spell books and broomsticks. There are also four secret entrances to the four secret districts of the Society; the Crystal Clock Tower, the Golden Windmill, the Amethyst Swan and the Fountain of the Red Herring. Also expect a number of magic spells (including harmful curses) as well as other surprise magical items.

Time - The book starts at night and continues to the day.
Weather - [Spoiler Censor]
