Hezcalipa was perhaps the greatest and wisest of the Couatl. Together with the blue dragon Ourelonastrix, Hezcalipa discovered the Draconic Prophecy, revealing a path to the future that did not have the Overlords.
Unfortunately, such a future also led to a world without the Couatl, a heavy price to be paid for the future of all other beings. Hezcalipa led her species in this noble sacrifice, giving up their individuality to form the Silver Flame and allowing the Overlords to be bound.
