Alledia, described by Silas Charnon as an "alternate version of Earth", is the primary setting of Amulet. Although the lifestyles of its inhabitants seem much less advanced, they possess a vastly superior line of technology, including mechs, airships, etc.

Alledia is devided into three nations: Lufen, Windsor, and Gulfen. There are numerous cities within these locations and all seem to differ accordingly in various style and communication. The two groups that inhabit this world are namely humans and Elves. Some individuals, such as those in the port-city of Kanalis, have been altered by an ancient curse that gives them the appearance of an animal.
