Whether it is set on Earth (past, present or future), in a parallel world or universe, or a mystic realm where the familiar laws of nature do not apply, Fantasy allows imagination to run wild. True to this idea, Fantasy’s many subgenres can vary from one another a great deal, encompassing just about anything one could imagine, which helps to explain the genre’s ever-growing breadth and depth.
The Court Intrigue subgenre of Fantasy generally focuses on and around royalty and the ruling elite. Settings can be anything from a well known historical backdrop (but with magic or something) to some unrecognizable alternate world but we are almost always going to be dealing with the upper crust of society and their despicable plotting and scheming. The plots of these stories are often complex and heavily entangled with politics, power grabs, espionage, assassinations (successful and attempted), court scandal and everything else that you would expect from a political thriller, but normally set in feudal, medieval-esque surroundings with sorcerers and dragons about.
