The world of Ajakai is a modern fantasy world similar to our own in most aspects besides the fact that it is imbued with magic. The majority of the story takes place in a kingdom called Thalass, which sits beside an ocean. Thalass is at war with its neighboring kingdom, Hiareth, and wishes to conquer it and take over its territory. Thalass' King William Richardson has created a law banning all use of magic except by the government, leading to a campaign to wipe out those who break the law. Ajakai, the capital of Hiareth, is a place filled with magic and mystery, whereas Anhedonia, the capital of Thalass, is a normal metropolitan city in all respects. Or rather, all respects but for its thriving underworld and blackmarket activity due to the ban on magic.
