The Age of Man
The goddess of Magic, Mystery, and Revelation
Referred to as the Wisest Sister, Seshat is considered by most to be the leader of the Celestial Church. She led the Celestial Church to slay the Dragonborn gods, she ordained Marduk as her husband and the new Morning Lord, and she bound all the gods to leave the physical world to allow mankind to chart its own course.
While her churches fund much of the exploration of arcana, they do little to provide instruction or guidance to the schools that study it. Leaders of the church say that they come to understand magic in an intimate way that cannot be passed on in the same way that knowledge of math or engineering can, and that the process of exploration is a critical part of the process of mastering magic.
