Whisperer

Mages that get their Power by contacting correlating Deity and storing it in their bodies.

Often associated with the figure of a Giver.
They have their separate list of spells.

PROS:

You are literally speaking with gods, each of whose have it's own unique powers, special abilities and sub-schools.
Your cast is limited, but good in one way.
The stronger your faith and closer to your god - the more powerful you grow.
You can force your will on body of your enemy or friend.

CONS:

Your cast is good, but limited in multiple ways.
Bad reception, you are unable to think, your god turned from you or just died? Uh-oh!
Toll on your body might be too high.

Every god that whisperer is in contact with gives them different focus in their ways:

All-engulfing Light: "Are you ready to shed your mortal possessions in search of your true limit of eternal?" You get the ability to boost your powers at a price of your - or other's - health, be it current well-being, or distant future of body itself.
Kella: "We'll know every move, be it seen or unseen." You get the ability to uncover past, shape the future, and balance the equilibrium of present. You can ask, and Kella will answer, be it question about the past, vision of the future, or a plea to change the events happening before your eyes.
Eternal Guardian: "Justice heed no call, but it will listen." You strike your enemies with all your might, if they threaten those you care about. Every act of true justice for a cause (the one you pick yourself) you provide makes you more powerful, and failure in providing it will make your inner strength suffer. You are also able to communicate with Eyes to some degree, making them your allies.
One Not Spoken About
Beast and Serpent: "There are two forces in you, and it's up to you to decide which one you serve." For your next adventure you pick the side, be it raging Beast or cunning Serpent. Failure to serve the side you pick will shatter your inner balance, negating the forces and confusing your view on life itself.
