Magic Circle

A Magic Circle (魔方陣) is a design or arrangement constructed to facilitate the use of Magic.

Principles
There are various elements which can be used within a magic circle and various forms which they can take - the simplest form is that of a lone circle.

Magic circles often include magical symbols in order to draw power from what they represent via Idol Theory.

Magic circles can be created through various means, from drawing designs and arranging certain objects, to using the positions of the stars themselves.
