As the numbers of the Giants and Dragons start to dwindle through their centuries long war, one of the mortal races - known only as the Axe-lords - rose up against the Ancients. The Axe-Lords united the various mortal, humanoid races in a powerful empire that fought against the Dragons and Giants, succeeding at killing many of them and causing most Giants to leave the continent alltogether. The Empire of the Axe-Lords is known to have dominated almost the entirety of Ussath Riel, which would make it the most powerful entity in its history, but at the end of the era, the entire race and its empire vanished in an unknown calamity, leaving only some of their ruins.
