Mages span throughout the three realms. Mortal, Heaven, and Hell. However, it is discovered that a fourth and possibly fifth realm exists. 

Time and space.

Aleius and Baltar challenge the seat of heaven, but soon discover the most powerful of mages to be enslaved by a threat hidden amongst the stars. 

In their inevitable loss versus the cosmic being, they return to the mortal realm with the help of their Deities.

Licking their wounds in the shadows of a powerless realm, they cultivate a new class of mages to combat what lurks in the voids of space.

This is my first novel so any and all comments and critiques are much appreciated!
