Beware, Beware, the Dragonborn Comes
Military: War
Circa 3,500 AC
After millennia of the primordial Titans being nothing more than a fable to most of the civilizations of mortals, the dragons make an explosive comeback. While the chromatic dragons that had gathered were relatively small in number, they came with a vanguard of half-dragon/half-man humanoids at their command.
Legend holds that metallic dragons came to the aid of the mortal kingdoms with draconic warriors of their own. Regardless of the truth of these stories, this is the first time in recorded history that marks the existence of draconic humanoids.
