A Power Unfolds

The Chain Breaker must find a way to unite power, or his realm will be destroyed.
The Forerunners have revealed their plans, and now Gavin and his team must find a way to stop them. Doing so involves coming to understand the powers of the world, including some that have been long forgotten.
Gavin has learned to fight with the team he's constructed, but this might be a battle fought alone.
And not by Gavin.
How can the Chain Breaker learn to let go of everything that he has been to be what he must become?
If he can't everything will be destroyed.
