Revenge of the Giants
As the Dawn War came to a close, some of the gods established contingencies so that the people of the world could defend themselves should dire threats appear out of the darkness at the borders of the world. One of these contingencies was the creation of the city of Argent ans the establishment of the Paragon Compact. This agreement between all of the civilized people of the world put in place a mutual defense pact, with Argent as the first and best line of defense.
According to the compact, it was the duty of every nation and empire to provide champions to serve as guardians and agents of Argent. In practice, paragon-tiered heroes volunteered or were selected through local rituals to takes their place on the walls of the Silver City. Vardar, Bael Turath, Arkhosia, Nerath – all these ancient empires and others regularly sent champions to serve in Argent.
