Azlant

Humanity’s first great empire, Azlant, stretched from coast to coast upon a vast island continent at the heart of the Arcadian Ocean. Azlant developed unparalleled art, philosophy, magic, and science. Eventually the continent of Azlant was shattered by a great shower of stones tumbling from space. The resulting catastrophe shattered the island of Azlant, wiping out its people and creating a ruin-laden maze of crumbling sea canyons where once a mighty empire had stood. Elves from the Mordant Spire, still ply these waters in an attempt to protect the secrets of the distant past from the opportunistic explorers of the present.
Ruined Azlanti colonies, sometimes no more than a few buildings but occasionally significant sites with signs of hundreds of structures, exist along the borders of the Inner Sea. Among these remnants, those that have not gone on to become cities of either Andoran or Taldor tend to either hold little historical value or else remain undiscovered (and thus are laden with almost unimaginable treasures).
Expeditions to Azlant reveal tantalizing hints of that nation’s ancient power and unique customs. That so many of their buildings survived not only Earthfall but also the ensuing 10,000 years of erosion and decay points to their skills in architecture and engineering as much as to their magical methods of preservation. Most Azlanti ruins bear a lingering aura of magic—sometimes the final remnants of this preservative magic serve to stave off the effects of time, yet in many cases this magic has at last begun to fail.
