Against the Giants, and Their Friends…

This awesome alliance shall certainly allow the giants to get their revenge for the defeats and insults of the past. They want to at long last reclaim the world they helped to create. To achieve this long sought after goal, the giants and elementals have set a new plan in motion to free one of the most pwerful primordials in the universe – Piranoth the World Mover.
