Military action
The Dragons rise up against their fiendish masters.
After millions of years of oppression at the hands of the fiends, the dragons of Argonessen, through the combined efforts of the blue dragon Ourelonastrix and the couatl Hezcalipa, rediscovered the draconic Prophecy and rose from their primitive state to oppose the fiendish Overlords, allying with the other draconic species descended from The Pheonix above, including the couatls. The common humanoid races of titans, humans, dwarves, halflings, orcs, and goblins, all still in primitive states on their respective home continents, hid from the god-like combatants and found a way to survive the great conflict.
