Theurgy

Theurgy is the act of producing miracles and unbelievable effects. Basically, it is the world's magic.

Ones who can produce such effects are known as Theurges. These Theurges have formed a world-spanning organisation known as the International Guild of Theurges (or IGT for short).

Circles
The IGT has divided levels of Theurgy into 9 Circles. Which Circle a Theurge is in generally shows how powerful a Theurge is.
