The Emperor Tanicus is revealed as a Worldbreaker. He leads legions of elves - and dark and monstrous creatures - across the ocean to stop the Revolution.
Caleb and the Revolution have swept across the land of humanity. Dwarves and elves join the human war for freedom from the Kryan Empire. But even if he can keep the army of different races from fracturing, it will not be enough.
To break the oppression of the Empire and defeat the Emperor in the battle to come, Caleb must find those who will sacrifice it all to bring the long-forgotten dragons back to fight for the Revolution.
